Stephen Hawking's Universe Time Travel Starship part 2 of 10

[playbonb3]

The other question is what kind of spaceship and what kind of fuel/energy would be able to burn continuously for 4/5 years straight. This looks good on paper but we're years away from realization.

[playbonb3]

What they fail to mention is "and it would take another 4 years just to slow down safely". Thanks Stephen!

[MrKoffeeKup]

Yea, so it goes to the future, but how would it get back, and how would the future be in the middle of dead space? What would be the point, other than hoping that your future kin had an empire that reached out that far, was willing to find you, and had the means to send you back home with a little going away present of advance technology?

[MrShaziman]

Stephen Hawking = 1 excellent 'snakeoil salesman'. Nothing he says can be proven and he uses Maths to discover the nature of reality. Only 'reality' is 'reality', nothing else. maths is an expression of what is discovered, you know, to codify everything, and a little grease here and there. One cannot use maths and theory to discover, and to get attention, to make money and to talk nonsense. hawking is a big misleader in the astrophysical (or cosmological) sciences.

[dunnono00]

@MrShaziman

...you had a rough time in math class, eh?

[MrShaziman]

@dunnono00 Maths is not the problem. The problem is; the place it holds in understanding the nature of the universe. It should not take first priority, or have infinite extrapolation. Maths is Maths. The universe is the universe. The two should not be confused. Theoretical Physics is just like religion. Take it on faith.There are other (much better and easily proven) ways to explain data (can't find a better word) coming in from deep space.

[dunnono00]

@MrShaziman

Yet the universe seems to be mathematically sound to a point. Again if you don't understand the physics and math behind much of it, you would think of it like magic. Let's be honest here, you probably only have a high school level of education at most, right? I'm not criticizing you for it, but let's face facts:

A random guy on Youtube blindly attacking an accomplished man like Hawking without any compelling ideas of his own. You are not looking good in comparison.

[PureWarrior]

how could you slow something down at that speed to prevent collisions? dumb question perhaps...

[llparasitell]

@PureWarrior that is kind of a dumb question because galaxies even though they hold trillions of stars they are so hollow that not even a single solar system collides when 2 galaxies run straight into one another.

Meaning you could fly blindly at light speed and literally never come even close in contact with a whole solar system.

[Slyer089]

1 dislike are U an Alien sir

[avmf8]

Parts seem to thin to take stress like that.

[mrsglennadiabiase]

people should make real life battecruisers and vikings lul

[kn1b1s95]

where are the other parts?

[Deonflame]

wouldnt it hit something

[AClarke2007]

Someones been doing maths on thought development!

[TheWolfDogMoon]

Planet Hopping with some kind of Terraforming might be more realistic. Use each planet as a staging ground to move to the next world. Over and over until we stretch across the galaxy.

[themanso08]

@TheWolfDogMoon lol that sounds like an invasion

[sean55719]

wait how are u going to guide something that big at that greata speed and miss all space debris??

[thesecrete1]

@sean55719 traveling at this speed we must modify the laws of gravity so if something werent to big it would hit it and possibly not phase the "spaceship's" path or speed.

[juki0h]

one little partical dust, and BOOM! dead

[SkateLikeABoss]

If you get lost, then that is a bummer...

[Wailot6]

yay and the chinesee would build it and we would exploit it

[417truthfinder]

First Skatelekeaboss I appreciate you vising my video/channel & I realize some people have the need to express themselves with profanity. I would ask that you remove this from your comment as I have viewers of my channel that do not appreciate so either remove this or I will delete your comment and access to my channel nothing personal

[Et3rnalRain]

so you'd only need enough fuel for 6 years to travel close the speed of light? wow. simple way to put it. But where we would get that much.. idk. We need to like.. come up with a way to get light to push things through empty space. since whatever traveling through space can only accelerate. it would eventually go the speed of light. Its just we as humans wouldnt be able to travel with whatever the object is. I think this could be possible since light is a particle as well as a wave..

[thesecrete1]

@Et3rnalRain light is a wave not a particle like a wave

[Et3rnalRain]

@thesecrete1 wave-particle duality look it up.. there are ways to get light to push things

[thesecrete1]

@Et3rnalRain i see what you are saying i misread what you wrote, i apologize

[GeorgeChar95]

of course this raises another question mr hawking.... you have the same place in Cambridge as Sir Isaac newton, so am sure you know about newtonian mechanics..... since there are no forces in space, you cannot stop that thing so you will keep going forever unless, you use gravitational pull to intercept the speed of the object or use rockets to the other side so it will take the same time to loose the speed as the way it got. Oh and the inertia is VERY high at such a big spacship

[thesecrete1]

@GeorgeChar95 you would have to use rockets because traveling this fast you would be able to over come gravitational field so i believe, so traveling this fast the laws of gravity will not be the same

[GeorgeChar95]

@thesecrete1 all of this are just theories my friend..... we have a loooooong way until we can prove any of these things. Take quantum mechanics as an example. It's very hard to understand them. I know that it applies as an explanation to the subatomic phenomena around us, but it might be more complex than we think. Remember than physics is not always correct. it can be a slight approach to truth. And the use of mathematics in these fields are very prevalent and i believe that this is incorrect

[Helge129]

@GeorgeChar95 "Just theories" do not exist in science.

Also, time dilation is proven. In fact, it has to be taken into account with GPS sattelites, or they'd give wrong possitional data.

[Mttgangster21]

yeah, earth is gettin borin and over crowded...if i had the money for it, i would give all to space travel.

[MrSoulTracker9]

time travel probably not, but it could be a means to more easily get to nearby inhabitable such as gliese 581g 30000 years away at current spaceship's speeds , 20 years at light speed make in-habitation much more likely

[gomezpiro]

Wow thats was nice !

[therasmet]

yeah but the prob is how will they calculate that they wont ram into a star? They can't change direction at such speeds!

[Et3rnalRain]

@therasmet why couldnt you change direction? the ship would only need a short burst in a different direction to move. Because once energy is applied in.. say left.. it will keep going left without any further boost. there is no resistance in empty space.

[thesecrete1]

@therasmet they shouldnt if they stay within a certain range

[tonyg445]

Now I want to live to see the future!!!

[killerbee04x]

STUPID....STUPID LASERS WILL PUSH and COLLECT ELECTRONS. LAERS ARE THE FUTURE. YOU ARE JUST STUPID.

[randomperson63758]

why don't we just use these space crafts to go to Gliese 581 :)

All we'd need is to build enough for the people who want to go, and we'd be ready :)

[thedragondragon4]

@randomperson63758 I want to go to Gliese 581 :( I give up on life here and this fucked up society.

[randomperson63758]

@thedragondragon4 i know ever since i heard about it, i wanted to go I mean, we can start new and maybe have a normal society that isn't obsessed with war, money

[thedragondragon4]

@randomperson63758 Me too :c too bad it takes like 70 something years to get there with the fastest most expensive space craft that hasn't even been created yet. *sigh* guess we're stuck on earth forever.

[randomperson63758]

@thedragondragon4 yea, but 70 years, thats still an amount of time that we stand the possibility of living. Ok, i'm 18 now, in 70 years, i'll be 88, and maaayybeee still be living. I mean, my grandpa is 90, and still kickin, so ya never know, some people might be able to survive the trip to Gliese, even if they were still in their late teens, or early 20s.

[dunnono00]

@randomperson63758

Or perhaps more feasibly, their offspring would in a carefully monitored "generation ship".

[thesecrete1]

@randomperson63758 could you imagine spending 70 years in a space craft that would be themajority of your life you would miss alot

[randomperson63758]

@thesecrete1 i know, and when you get to Gliese, the rest of your life is probably 5 to 10 years from ending anyway. But, at least whoever decides to go, will at least live 10 years on Earth..... :D

[thesecrete1]

@thedragondragon4 what is Gliese 581 

[GhostofTahok]

where is pt 1 & 3?

[tonyg445]

We should put robots in space so we can blast them at this speed!!

[serpentphoenix]

This is such a BS ship, how the hell does a spaceship NOT have radiators in space? Google Atomic Rockets to learn about realistic starships and how they would be built IRL.

[TheBahram203]

not possible, If something travels at the speed of light it would melt

[Dinoboy05]

@TheBahram203 thats why it said 90% the speed of light

[thesecrete1]

@TheBahram203 it would not melt

[Alfredox314]

Now, How you stop it?

[Greev84]

@Alfredox314 Easy ,, you hit Break, and wait another 6 years for it to stop =)

[Helge129]

@Alfredox314 you turn the ship around and fire the main engines. Simple as that.

[thesecrete1]

@Helge129 put rockets on the front then you dont even have to do that

[Alfredox314]

Now how you stop it?

[Desmonddd2002]

The sad thing is i think no-one watching this video would be on board that ship..

nor with Dr. hawking.

[takeoff108]

its chuck norris's private airplane

[5000mahmud]

unless we find a worm hole that leads to Gliese 581

[5000mahmud]

we wont be going to any other star systems in are life time feels bad :(

[SteadySkill]

And what happens when you hit head first into asteroid while traveling at 0.8 FTL?

[averyfatsnail12]

I love the music!

[shivanajames]

I love videos like this

[DevilMayFry]

Unfortunately, if you think realistically about it, there's no way we'll be able to get that much fuel for the sake of science. Corporations and governments like money way too much.

[Specopleader]

@DevilMayFry Yes, but the situation of society is much different right now then it may be 100 years fom now. Priorities between governments and society itself may change drastically.

[thesecrete1]

@DevilMayFry when "time travel" was first brought into existence by i believe it was by einstein im not sure it was never ment to be accomplished i was just to be known

[MegaSTARLIGHT19]

Its amazing tp think in just a few generations time that this, conolizing mars and the interstella spaceship could be a reality

[PalmyBruce]

If the craft accelerated that long over that much distance, wouldn't it be likely to collide with things like meteorites and planets etc. on the way? Is it steering in any way, or able to avoid things?

[paldesic2009]

How on earth would that slow down

[xRieZx]

@paldesic2009 parashute

[Specopleader]

@paldesic2009 Lol, true. "Sir, we have sighted a potential planet to colonize"-"Deploy the air brakes!"-"Sir, the ship does not have brakes, and no air in space"-"Dammit we missed our only chance! Fuck!...I'll be in the cryo-chamber, wake me up in 2 years"

[paldesic2009]

@Specopleader will smash into an asteroid way before it got there.

[Dalekdanceparty]

It's beautiful to me that we have all these sounds that we associate with rockets in space.. i mean we all know that sound doesn't yadayada in a yadayada.. but still..

[HarveyPriceFTW]

We are not fit to visit other worlds just yet

[rickythepitbull]

Wresnix we only need to figure out how to control gravity..

[wresnix1]

no one can travel in the speed of light coz space ships and human body will be melted. in my very opinion before we travel in light speed first we (human and spaceship) must be transformed mater into energy and reform again into mater. in other words we must find teleport technology  (like star trek movie).

[Stijning]

if in any way alien's would atack us in the future, there is only one way to stop them.. attack them first

[Dalekdanceparty]

@Stijning has somebody read Ender's Game?

[lukeveijk]

if their was no such thing as diplomatic issues. trading.

competition of what country is the best is what..

and ofcourse no war...

we could really achieve stuff like this.

[ThePengwyn]

and then it has to slow down again haha :p

[0Th3CastOut0]

its not so much time travel as it is bending their perception of time a few years for them would be a few decades or more for us

[mysistersfister]

how would we handle the g force



[natsukage123]

@mysistersfister we'll look at that later :P

[Acrimonator]

What's with the narrator voice, it's like something bad is going to happen...

[armorhide406]

is the space controller voice provided by the same dude that does hawking?

[armorhide406]

thats a huge plume

[kevin212122]

How do you stop a ship that big going that fast? :D

[armorhide406]

@kevin212122 brakes :D

[kevin212122]

@armorhide406 ...Oh ha ha ha. :D

[Superdude899v1]

@kevin212122 With a cosmic fishing net (jk)

[kevin212122]

@Superdude899v1 ... Your braking ideas are really creative.

[Tropicsca]

it looks like a void ray

[Tropicsca]

why do these videos have to be 3 minutes long in ten parts??

[verzeda]

man, this seems like the sort of program trekkies watch while on LSD.

[OrionHeights167]

I wonder what would happen if that craft hit a spec of dust going that fast?

[prana19]

i love how this is so far in the future, yet the guy is worried about the amount of fuel; as if they're gonna be using gasoline.... ha...

...no but seriously, im happy to be apart of this generation and not in with those idiots that thought the world was flat.... yep, we know everything now... all things. us. yeeaaaaah.

geez.

[goalieborn]

@prana19 well you need an infinite amount of energy to reach the speed of light because light is the speed barrier and all energy is calculated by the speed of light

[geniemist]

1:57 wouldn't it hit one of those?

[kevin212122]

If only Albert Einstein, Stephan Hawking and all of the other great minds of the world both past and present were able to meet and discuss there ideas and to experiment. There is no telling were our intelligence would be now.

[ZachRose88]

@kevin212122 Or if religion had not held back the progress of science and humanity for so long. The middle east used to be the center of all progressive thought in the world before the advent of Islam ruined it and stifled countless brilliant minds therein.

[kevin212122]

@ZachRose88 ... I am assuming you arn't religious nor am I self. But religion in my opinion is only an excuse and an answer to questions that humans don't have the answer to yet. That is why religion now is being threatend because they know that "science will win because it works" Stephan Hawking quote.

[Narftaxaku200]

@kevin212122 TRUE!

[masteruploader1998]

@kevin212122 mad science ;D

[661Sunshine]

@kevin212122 Very true, they should discover some sort of immortality pill for these people

[Superdude899v1]

@661Sunshine Scientist are currently looking into this chemical that slows the genetic decay to a near stop, in other words, near- immortality

[661Sunshine]

@Superdude899v1 pretty interesting man :)

[julianlava]

1:22 it sound like popcorn XD

[TheXenoChemist]

I hope this actually happens someday.

Why?

Simple. Because the lights in the sky are stars.

[newtownlegends]

@TheXenoChemist

This show is a bit of a bummer for me. I can't see the discoveries that changed the world, and nor can I see the discoveries that will. Will there be discoveries as monumental as of other solar systems when I'm gone? Probably. I won't see anything even close. I won't find out if we can get to Gliese 581. I love Earth and everything on it at this time, but it's a whole lot of bum that I can't time travel (:D) and see what happens when we do.

Stephen.H is da freaking bomb :D

[TheXenoChemist]

@newtownlegends: I know what you mean, but chin up. Awesome discoveries are being made in the present. If you want to see a future where humanity can achieve something like the project in this video, then study hard and advance science. You don't have to become an aerospace engineer to make a difference. You can work in the life sciences to advance human health, or study ethics, politics, and/or economics to figure out how to build a better society where a project like this can happen.

[maskscraper]

USS Hawking???

[Alistarb25]

the best part of this is it gives me HOPE

[PlaneAU]

@Alistarb25 but you wont be there when it finally happens

[777lucifero]

@Alistarb25 every thing leads to another.. naturally. it's like the inventions of leonardo da vinci.. they were incredible for his time, unthinkable... yet, they served for nothing, as they werent discovered until centuries later. meantime, other minds had (re)invented his things. what i mean is, if einstein hadnt discovered about relativity.. the next genius would have.

[leopoldvs]

@Surfaholic96 Thank you Sir! :)

[khimeraslayer]

pilot: "oops.. asteroid!"

[leopoldvs]

...for ex.: when we think of a place (say Paris), our flesh is not there, but my thoughts are, in a matter of micro seconds. If only we could find a way to materialize our thoughts we would be in different places no matter distance/space or time...

[leopoldvs]

If we had asked ancient Egyptians who the world would look like in 4000 years in the future, they would have answered: "Well, it will be full of Piramids but much bigger and taller!"...I think, in the future we won't be travelling using terms of "SPACE" and "TIME", there must be something else, something we don't know yet; for ex...

[TimeTravelTruther]

O.K. what about the micro meteors. At that speed the micro meteors would tare that ship up :)o*o

[carlsm95]

@TimeTravelTruther well it is assumed that if a ship could travel at nearly the speed of light, wouldnt it have the technology to protect against space debris? Think about how many years and all the tech it would take to develop a ship travelling near the speed of light

[cr4yv3n]

how can  one NOT like this? :S

[TimeTravelTruther]

@417truthfinder Are you really seeking the truth. I wrote a book how to time travel and teleport your body to any time and space. (Dot Training) The truth is you don’t need a machine to travel in time & space. All you need is within you :)o*o

[shaunnoob]

What what what is the soundtrack played during the start of the clip called? anyone? please...

[CaptainAndrew1991]

@shaunnoob "Moving Mountains" by Two Steps From Hell.

[cr4yv3n]

@CaptainAndrew1991 sounds a bit better than the actual track - know where i can find this exact one? ( without voice ofc :P )

This sounds more...technical :D

[Ascari7738]

@cr4yv3n Hey again, bud.. I wanna ask which one u mean in this vid? The piece of music at the start of this vid or the one starting just after halfway? 

[teraflop122]

@Ascari7738 I don't know about him, but I'd sure like to get ahold of the piece starting halfway through.

[Ascari7738]

@teraflop122 I'll try my best 2 get u that piece of music, bud :) And the starting one 4 cr4yv3n..

[Ascari7738]

@teraflop122 HEY WAIT!! WTF is wrong with me?! LOL i already HAVE that one on YT! lol check it out, it's called Alien Ocean XD

[teraflop122]

@Ascari7738 That's hilarious. I totally skipped that when searching for it earlier. I was all like, "Nah, this can't be the song. What do alien oceans have to do with starships?" Thanks for the upload, these are some great songs.

[cr4yv3n]

@teraflop122 yeah me too.

I was like : "well it must be the one with time travel and all that astronomical info" O.o

[shaunnoob]

@CaptainAndrew1991

Thanks very much! jesus trying to find it AGES!

[CaptainAndrew1991]

@shaunnoob It's a bit of a coincidence that I just happen to be an avid listener of TSFH and watched this at the right time... lol no problem.
