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
@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.
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.
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?
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
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.
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
@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)

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. :)
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 :)

@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.
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.
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.
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.
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.
@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
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
@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.
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."
@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
@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
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.
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.
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)
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.
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! :)
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,
@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.

* 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.

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.

@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

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

@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
Muralidharan001 11 months ago
@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.

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 11 months ago
@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 11 months ago 2
@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."

sarkerm2 11 months ago
@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.
Napalm13092 11 months ago
@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.
MartinJWillett 11 months ago
@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 11 months ago 3
@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 10 months ago
@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

19Tranc3r92 11 months ago 2
@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.
GamingGuru96 11 months ago
@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

BigLouieLittlePhilly 11 months ago
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.
