  • Great use of Stellarium!

  • Takes 16 - 20 hours just to send a command to the Voyagers

  • Will any thing in the ort cloud hit them?

  • ther is one way to get to alpha centauris or whatever:p ...some genius find a way to trap and secure DARK MATER....and he sad that that whit tis energy we can travel exrtemele fast by spaceships..... hmm i wonder if thath AVATAR movie is true....well atleast the spaceship part...cuz from my opinion it can be dun....if the fucking polititions give some monie for the spacemonkis:D

  • its sad that when i tried looking for this vid the first 10 results were eminem videos. why isn't this #1?

  • wheres the sound

  • BuBBlicious

    o O BloBeria O o

  • this is assuming that the probes don't get destroyed during their travels 

  • its amazing what will happen in the future.voyager 2 will pass by Sirius and i hope that the human race is still around to celebrate this achievement. plus they will have they more futuristic and more modern engineering

    everybody, have faith that we will be here,on this planet,to celebrate this :)

  • We are the hicks of the milky way lolololol. But all joking aside, that would mean other beings in the middle of the galaxy would have a easier time reaching other stars right? So for us to get to other places in the our galaxy we would have to be more advanced.

  • maybe if the megatrillions of dollars our world wastes on WARS against EACH OTHER went towards SCIENCE something like warp drive or hyperdrive or stargates or some other loophole in the laws of physics could be discovered? Science fiction often becomes science fact but our species is STUPID AS HELL

  • @Zurround100 Not stupid, controlled. Get it right.

  • Tony you are my hero for uploading these videos. On a side note... lol @ nobody even bothering to respond to wildthing's comment.

  • and wtf did that cost the tax payers???

  • @invizible2u One hell of a lot less than the wars of choice Bush got us into!

  • @invizible2u Why\at does it matter? These so called "wars on terror" and "wars on drugs" have cost us alot more then astronomy has, and sadly, most likely ever will.

  • @invizible2u A billion or two?

    The US military budget is over a trillion dollars, you moron.

  • The funny thing is in those 40,000 years we would of created better tech and probably overtaken them. I'd love to see the look on the faces of the humans that, in say, 10,000 years overtake the probes we have only just sent into space.

  • dam it i wont be alive when they get there and we all celebrate

  • Thank you for this excellent video.

  • 4:44 of nothing new :/

  • @omma911

    4:41 mins of something new TO ME ( and maybe others )

  • i think we better get it right on earth before we "pollute" another system. Maybe thats why we havent "got" that speed technology yet...We are still funding wars instead....hmmmm, crazy hey.....thank you for being here Tony...Another thumbs up

  • Even when we stumble the idea of how to travel to other stars by traveling fast enough to get there in a persons life-time...how do we intend to slow down this object?

  • @MrAwesomesauce101 plus we would have to travel to the end of the supercluster in order to get dark matter.

  • Our black hole in the center of the galaxy could serve as a worm hole but very briefly in order for it to stay we need to put dark matter in it but there's the problem of randomization. If we do make a worm hole we could end up ANYWHERE in the universe witch could be a bad thing like in the center of a star or near a black hole or a planet near a collapsing star etc. But I still really want to explore other galaxies but the technology for centuries squared will still be to primitive.

  • thanks tdarnell. you make this worth watching. me and my girlfriend are watching every episode here in denmark on our tv. this is real quality stuff. Keep it up. 

  • Dear Tony, I just wrote a full length post, but it didn't post, I'll just abreviate it though.

    How about the antigravity technology that was developed on earth roughly 100 years ago? NASA doesn't need to be concerned that about the publics reaction. The people of our planet, the public, are well equipped for the knowledge that we have had antigravity technology for around a hundred years. Zero point energy/ antigravity technology is and has been known about and has been developed within NASA

  • beautiful tony. especially the bit about the greeting cards...get in!

  • Stellarium!

  • I dont think the speed obtainable with our chemical rockets has by any means reached its maximum. I once read that even with New Horizon's gravity assist from Jupiter, will shorten travel time by about 3 years. The downside is that the craft will travel much faster when it reaches Pluto and thus shorten the analyses time of Pluto considerably. The reason why NASA opted for a shorter flight time is that Pluto's atmosphere may freeze up before New Hor gets there.

  • but then I would never reach the nearest star walking because space expands faster than I can walk lol!

  • So let me try and get this right. If I was able to walk from earth to our nearest star - then if I type 00 these two zeros and put 1 before them - I would have to keep my finger on the 0 until they filled the screen on my laptop to cover the amount of years it would take me?! How bizzarre

  • how far is a ly? is it 50 trillion km from point a to point b ?

  • @sowhatsnew205 a light year is the distance light can move in a year. light moves at a speed of ~3e9 meters per second. so in one year is (60*60*24*365) seconds so one lightyear is ~ 9e15 meters or ~9e12 kilometers, or 9,000,000,000,000 or 9 trillion km.(e=10^x not eulers number)

  • @tuseroni oh...I was close then! lol. thanks

  • Thank you very mcuh for your videos!!! One of my best personal friends are NASA HQ Dr. Adriana Ocampo, Vojagers and New Horizons , Dr. Lawrence Lasher from Pioneers and Dr. Rosaly Lopes from Cassin...Clear Skies!!!

  • I believe that this is one of the factors that will lead us to discovering intelligent alien life existing on other planets. As technology continues to progress, devices that we send out to explore the out-reaches of space, will, inadvertently, signal the existence of these other life-forms, or, be discovered by them. The SETI project has one goal, but, other things that human beings do with this kind of technology will speed up the process of discovery. Stay tuned. :)

  • Thank you Tony, for your excellent space videos!

  • Tachyons, so much faster than light.

  • fascinating, as always!!!

  • The only way we're going to help Earth is to get off it and explore our water supply as well as the galaxy.

  • I predict we will create a faster probe that will overtake the voyagers and get there faster.

  • again a great vid tony

  • One mistake in the video. New Horizons does not carry any sort of greeting, unless you want to count Clyde Tombaugh's ashes. Alan Stern really screwed up by not including anything.

  • I'm interested in 'The Great Filter' (you mention at end). Is this a recognised term, or a TD one, and could you go into it a little? GREEEAAAT vid, btw- it does my head in that these objects will just go on and on, deeper into space for ever.

  • To think over tens of thousands of years needs a very fast thoughts if average thinking time is confined only 70 years. What might be the speed of a thought? No, not the speed of a reflex but the thought itself. Does the light which origin is unknown pass an eye without raising a single thought? Or if the thought has only one end of the line it can not be understood? If thought is not faster than the all directions spreading light then it can not be seen.=Thought is faster than light :)

  • Man! Your vids make me feel so humble and so grateful to be alive. 

  • Great video man..that’s why i subscribed. It never fails it seems in every channel regarding space and science and what not there will be religious fanatics coming out the work. You all should go to a street corner and preach your garbage. once again love your work tdarnell....

  • @djbb975: V'ger was Voyager VI in Star Trek: The Motion Picture.

    @tdarnell: You keep referring here to Pioneers 1 & 2, when you're actually trying to say Pioneers 10 & 11. The longest-lived deep-space probe we launched was, if I recall correctly, was Pioneer 4, which orbited the Sun between the Earth and Mars. Pioneer 10, although considered dead, is the furthest probe out. The Voyagers are not the fastest probes- New Horizons is presently the fastest probe. (Might even be a Mariner probe that

  • @dmfalk Whoops, meant 10 and 11. Need to pay attention to detail more. Thanks for letting me know. I should only have said it once though, not repeatedly.

  • Voyager 1 returned as "V Ger" on the 1st Star Trek Movie..

    then those bastard Klingons blew up Voyager-II as target practice on Star Trek V

  • @djbb975

    The Klingons actually blew up Pioneer 10, not Voyager 2.

    It will be done by Captain Klaa with a Bird-of-Prey in 2287.

  • @KKM121 Shooting space garbage is no test of a warrior's mettle!

  • I grew up with the Voyagers. After almost 34 years, they are both still alive, although Voyager 2 has a history of close calls:

    * Its primary transmitter failed within the first year. It has run on its only backup for 33 years.

    * At Saturnus, instrument platform jammed. Mission-Control unjammed it.

    * Just before Uranus a cosmic ray damaged its computers.

    *Last years another Cosmic Ray damaged its computers.

    Luckily, Mission-Control reprogrammed the computers to work around the damage.

  • we need those generational ships!!

  • Excellent! I often wondered how far the probes are currently. The timescale is mind blowing.

  • I think we're more likely to catch up with them in the future and recover them before anyone else gets their hands on them

  • Comment removed

  • Hi tony, I was wondering if these man-made objects will take so long to arrive at our neighbouring stars, will they degrade in space? Or is space so element-sparce that they will arrive in pristine condition? I'm referring to the shell here, not the battery life/electrical equipment etc.

  • @peha2 Yes they will. There's a lot of dust in the interstellar medium, along with other tiny little rocks floating all over the place. That debris, coupled with cosmic ray hits, slowly degrade the spacecraft and electronics.

    No matter what, the voyagers are slowly dying.

  • @tdarnell They say both will be around in 1 billion years but as of now all the electrical in them both are dieing

  • I so believe life out there. I even believe they visited Earth too~

  • What is the maximum speed we could achieve using gravitational slingshot within our solar system?

  • Does New Horizon also carry a greeting card?

  • If anyone does find the probes, I suspect it will be humans, or some descendants thereof.

    And they will likely have LONG forgotten about it by then.

  • We are still in the 'chemical' age of space exploration, which makes interstellar travel currently impractical, buy once we develop efficient pulse fusion and/or mini-magnetospheric plasma propulsion (M2P2) drives it is estimated we could reach speeds of up to 10-20% light speed, meaning we could reach Alpha Centauri in just 43 or 21.5 years respectively.

  • We humans seem to exist in a sped-up hyper-reality next to the slow pace of the universe. 40000 years seem like an eternity to us but it's not even a tick of the universal clock. Also consider the possibility that by the time these probes reach the stars, they may well find them already colonized by our distant offspring.

  • @Danny77uk If you go to the very small scales, we are at the slow pace.

    But that is a nice thought you had: we being merely a sparkle in the vastness of time and space.

  • One thing that really bakes my noodle is the Pioneer anomaly. I wonder what's causing it, as I bet many others do.

  • @jozeer88 what is the Pioneer anomaly pls?

  • 3:39 You've used some Dutch text in your story, nice:). Thanks for using my music again Tony!

  • Anyone else going to start a Mass Effect playthrough after this? Heck im going to have a Darnell marathon then jump into a new playthrough!

  • It kinda sucks that we don't have this technology to go faster and farther. What we are missing out on sucks. It's kind of depressing.

  • Did we construct Voyager 1 to be the fastest object ever, or did that happen 'accidentally' (due to natural causes/gravity assist, etc?)

    D'you reckon we could catch up with Voyager 1 if we were actually trying at speed? Half the speed of Light sounds good enough to me! :)

  • thats awsome man

  • The intro background seems incredible to me. Just because when you look in the sky all the stars are right beside each other and you can't really picture them so far away. But in intro, it just shows me how far the closest points we can see really are.

  • Amazing to think that if the human race becomes extinct we have these spacecraft as our legacy and they will probably be floating around long after we are gone,perhaps they will eventually be the only evidence that their was ever life on earth.

    I doubt anyone out their will ever find them though,just a speck of dust in space.

    Ive read about the canceled project orion which was a nuclear powered spacecraft that would reach a star in a few decades,kinda like a star trek voyage.

  • @amurphy245 I read some time ago in 4.5 billion years when this planet dies providding it is still in one piece the Pioneer probes will be 6,000 light years away, and the Voyager probed will last about 10 billion years, and will be 14,000 light years away.

  • "VGER!"

  • Thank you again for an informative, fascinating video.  :-)

  • Kinda like a message in a bottle, you never know who will pick it up - let's hope it won't be the Borgs ;-)

  • @detersgumig I think it will be the Klingons, shooting space garbage

  • I want to cry .....but am at work

  • Yes, moar! Great stuff.

  • This is the kind of stuff that got me to head to my local university today to apply for a physics major.

  • i love how you got subtitles incorporated into your videos. It makes easier for people whose native language isn't English to follow what is said. Even though your voice is as calm and comprehensive as it gets. Cheers.

  • Just beautiful. 

  • So beautiful! So wellspoken! I aboslutely loved it!

  • Lisa may be able to help Voyager.

  • Great vid :]

  • how does the probes move in space? do they have jets push them or just gladeing?

  • @kiwiterran1 There's very little aerodynamic drag in space so they used their rockets to leave the earth, then used gravity to speed them up going around Jupiter, so they just keep going and going

  • @kiwiterran1 i think using the inertia principle

  • @HiMootjeuh wat is inertia principle?

  • I know one of the space projects, Nasa collected 10,000 signatures to be placed on the probe so at least my signature is out in space,

    Great video, I watched it twice right away.

  • Our space technology is too young like 60-70 years. Annihilation reactor can b huge hope in future to achieve speeds like 1/3 of light speed but we have develop a shield to displace near by objects coz at such huge speed a small stone can crash a huge space ship

  • @Muralidharan001 like star wars ? xd

  • @Aladoniss Every satellite has array of solar cells. U may think from where it gets much EMR well may b combination of EMR from star surrounding us and may also cosmic EMR. Remember motion is not powered by this, space has no medium and so no resistance so speed will not change until there is significant gravity over it or hit by space particles

  • @Aladoniss I think they are using solar energy to power themselves and should keep recording and sending data as long as nothing else smacks into them and knocks them around. Or at least that's what I think, do not quote me on it.

  • Another great video! keep up the great work Tony! =D

  • 4:20 "every probe we've launched outside our solar system carries one [greeting card]"

    Does this mean New Horizons is caries a greeting card as well????

  • another great vid Tony!

  • Everything is strange. And the core of every atom, everything we see must also be infinite..

  • ET needs to get over his/her shyness and break some bread with us. We could use some new technology to visit other rocks.

  • Thank you Tony for another wonderful video; really appreciated the work you do.

  • superb

    

  • Very nice video tony

  • You know we dont actually have to travel places to get there if we stopped being so silly. Objects do not exist in space and time. Space and time are properties of the objects.

  • That computer interpretation of Voyager 1 showed all kinds of little scratches and nicks on the dish. Since space is a subzero vacuum wouldn't the prob be as pristine now as when it left Earth? Unless of course it can into contact with debris such as tiny bits of rock and the such but at the probes speed and the speed material may be flying through space wouldn't it just destroy the probe? The way I look at it that thing is either spotless or it is a multibillion dollar cluster of shrapnel.

  • @Napalm13092 Empty space isn't really empty. Any probe passing through our solar system will pick up hundreds if not thousands of minor dings from dust or ice particles. And that's before you consider the rest of the crap flying around our sun. So hopefully in a few hundred years when we have the technology and we send a ship with a crew to salvage Voyager 1 and place it in a museum, we can look at the damage caused to it and wonder how the hell it ever survived for as long as it did.

  • @TacticalAtheist I can just imagine our ancestors thousands of years from now with the technology to travel interstellar space finding Voyager out there. "Hey Dan, I think I found something!". "What the hell is it?". "I... I think it was on of those record players you hear about in history holodisk on the 20th century. Here look it even has a record attached to it and judging by the naked couple on the cover it is some kind primitive form of porn." "Meh, prob isn't worth anything scrap it."

  • what gives it speed? is it just momentum? like you push something in space and it keeps moving?

  • @sarkerm2 Newtons Law: An object in motion will stay in motion unless acted upon by an outside force. Since space is a vacuum there is nothing to slow the Voyager 1 down unlike here on Earth where you have to contend with the atmospheres friction and gravity pulling you down (That is why automobiles and aircraft are aerodynamic and space craft are not). It will keep it's course through space at a steady speed unless it comes into contact with another object or it's gravitational field.

  • @sarkerm2 Yes. Moving objects continue to move unless acted upon. Down at the bottom of our gravity well on the planet surface everything we see or experience in some way gets acted upon by drag or friction, in space those forces are infinitesimal.

  • @sarkerm2 To add to what others have said, all of these spacecraft used gravitational slingshots to build up speed. As they whipped by the planets they got a boost that increased their speeds to the point where the Sun's gravity couldn't hold and they were flung out into interstellar space.

  • @tdarnell Hi Tony, I don't get it, how can these probes get speed from the planets? Any speed they pick up from a planet when they approach it, by trading in 'height' for speed, they will loose again when they are beyond the planet, where they will trade their speed in again for height (potential energy its called?). That way, all a planet could really do is change the course of the probe right? Or am I missing something here?

  • @gjvdkamp The probe already has to be at a high speed when going in for the gravitational slingshot, when slinging in toward the planet at the right trajectory, it picks up speed, but doesn't loose too much of it afterward, since it would be above escape velocity. I think :P

  • Just started some heavy reading on the Fermi Paradox, so I find this video well timed!!

    Thanks for the top videos TD, I love every one of them :)

  • my favorite Youtuber strikes again!

  • What did you mean by saying "surviving The Great Filter"? @ 4:32

  • @19Tranc3r92 Well, currently us humans don't know how likely it is that the are other lifeforms out there. The precise events that unfolded on our Earth, may be something relatively common to planets lightyears away, or it may be a totally perculiar thing, perhaps we are the only sentient life in the whole galaxy? Or who knows? The whole universe? The great filter refers to something that next to no evolutionary life can pass to survive, we survived it, but we are not sure what exactly it is.

  • @19Tranc3r92 It may be from the time that the meteorite struck earth and contained living bacteria. Perhaps it is incredibly unlikely that something like that would of ever happened, and if so, That is the 'great filter'. Maybe other things such as a certain path of evolution that allowed us to be who we are, is a very unlikely path and perhaps there is only a 1 in 1 trillion chance of that happening. That again, may be the great filter. Maybe there is many great filters, and therefore other

  • @19Tranc3r92 Lifeforms out there are extremely unlikely. Does that sum it up? =)

    

  • @19Tranc3r92 Check out Life in the Universe #3: The Great Filter. I try to explain it there.

  • Being a probe is a lonely job :(

  • =D

  • Kewl

  • its impossible to leave earth and travel through space with the speed of light. keep dreaming we all gonna end here. you probably watch too much science fiction movies ;-)

  • But the problem with this is that none of those probes have a propulsion system to increase their speed. If they had had a large ion drive which had been operating since they had left by now they would be a lot further than they are now. It will go a lot faster if we actually have constant propulsion.

  • There's gotta be a way to break the speed of light cause warp speed is just kid of impossible, to warp the space and time you need more power than a blackhole.

  • @dante2k8 There's no point in braking the speed of light, anything travels faster than speed of light will go boom boom.

  • I want my warp drive, damn it!

  • Generation ships are an unsettling idea to me. Imagine being born, and dieing of old age in a space craft.

  • What is "the great filter"?

  • @tsjoencinema

    Look up the fermi paradox.

  • @FlowCell thanks

  • @tsjoencinema I also made a vid about it, Life in the Universe #3: The Great Filter.

  • @tdarnell oh yeah... Sorry. I remember now.

    I love this subject. Interesting as it is, thanks so much for making it more interesting. Can't wait for your next video.

  • "Send more Chuck Berry!"

  • the crazy thing is for all we know probes like these could have passed near our solar system before we had the technology to detect them

  • I wish more science fiction writers would learn to accept this, we could tell fantastic stories using our own solar system. But it's become a norm to chuck relativity aside and jump on a starship to a distant alien planet.

  • Comment removed

  • In a couple million years an alien will open the "greeting card" and laugh at the size of the man's package.

  • In this there was the constellation canis major. Just wondering, is the hypergiant "VY Canis Majoris" in this constellation? If so it would be much easier to find (I can't seem to find it online)

  • @Aresftfun Yes it is. I promise to make a vid on this topic soon as I've gotten many requests.

  • However, it's those same hopeless distances that give room for life to spring into existence and develope freely without being harmed by the hazardous space it evolves out of.

  • There must be a very strong radiotrasmitter in voyager , to send signals that far?

    Is the Voyager 1 equipped with a camera to send pictures also?

  • How come the Pioneers stopped functioning?

  • @TheDivineWinds Deterioration and power loss. They just burned out.  They lasted well past their design lifetimes though.

  • Humans need to stop killing each other and explore the universe (inner and outer).

  • I love watching your videos !

    I check every night for any new videos

  • Gotta love Voyager, making history every moment :) Tony I want to hear you on pbs or something!

  • I makes me feel kinda sad....

  • always love your videos!

  • Mr. Darnell, I really enjoy these videos! Thank you for making them. If I may say so, your voice is perfect for your videos! It makes the whole atmosphere. Keep up the great work and Keep Looking Up! :)

  • a message in a "Bottle". great video. Thanks

  • I like to dream.

  • that really interesting and awesome, i never knew that scientists put information about earth and humans inside the spacecrafts for other beings that may exist out in the universe :D

  • at the same time humbling and frustrating that to reach those very close stars

    i hope i can live to see men stop spending so much resources in weapons and nukes and wars and start to work together in a way to travel a bit closer to the peed of light,

    we can do it if we joun our resources

  • @StraussBR Why would you want to do it? Don't slap me down for this ultimate heresy, just answer the question: why bother?

  • @MartinJWillett to boldly go where no man has gone before. for the simple joy of the act of doing something noteworthy. space exploration is the collective symphony of our greatest scientific and engineering minds focussed on one ultimate yet indescribable goal.

  • @SuperHighFiveGuy All very orthodox and as you have been programmed to respond, and to expect validation and approval for, but it doesn't begin to answer my question.

  • @MartinJWillett ok to debate on other channels is it martin ? but any debate on your channel gets people blocked .

  • @sausage4mash This isn't my channel, my rules don't apply here. I don't impose my rules elsewhere, when in Rome and all that.

  • @MartinJWillett

    because it is the next step torwards human evolution

    you and me might not live to see anything of that, but that should not demotivate us

  • @StraussBR What makes you think that you know the next step for evolution or that evolution has plans? What makes you think that evolution is a good thing or that your interests coincide with it?

    I'm still waiting for an answer.
