Neil deGrasse Tyson - How long until humans get to another galaxy?

how long do I think humans get to another galaxy until we get to another galaxy you want to go there okay so here's final and I will end on this question you had the final question of the night okay you want to go to another galaxy you don't like the Milky Way apparently it's oh she said it's average hard to please women here I guess okay there are bigger galaxies than the Milky Way all right we'll make a list for you later the guy the guy here says size doesn't matter lady disagrees apparently so you want to also galaxy Google in 87 that's it has a trillion stars trillion you know what we'll take the count to a trillion 31 thousand years you cannot count the number of stars of that galaxy sounds like that galaxy is made for you alright as an awesome black hole in its center that's gobbling up all the matter clouds and stars that come by it so you want an interesting galaxy to visit so here's the problem here's the problem the fastest spaceship we've ever launched fastest it's now on the way to Pluto there's a rule in astrophysics if you do an experiment you need the experiment to end before you die okay so to get to Pluto they got a very light space probe and put it on the biggest engines rocket engines we had so that way you have low I trust you have high speed and that's me and I forgot the exact speed some time she got to the moon in six hours when it took astronauts three days to get there all right and pass the moon in six hours after watch it book getting out there if you if you hitched a ride on that and said aim for the nearest star not Pluto because it was going to get to Pluto in just two years two or three years and it's go take it to the nearest star this fastest hunk of hardware that humans have ever launched when would you arrive at the nearest star to the Sun fifty thousand years from now that's the nearest star to the Sun now if two bumblebees that's really tubes here I'm not use my probably says two stars out of 100 billion the new stars for light-years away I just found an earth-like planet around that star by the way take you fifty thousand years to get there how about across our galaxy we are a hundred thousand light-years across even if you could travel the speed of light and we launched you said goodbye you will arrive at the other end of the galaxy 100 thousand years later to us and then by the time you got back we will all forgotten about you all right if there's civilization at all now in Star Trek they got around this problem they invoked the warp drive what they said was we're here the edge of the galaxy is far let's warp the space between there and here okay so there's the galaxy and then you warp it and then you take a bridge what's essentially a work ball but the concept didn't exist at the original Star Trek later on they were introduced it you go cut through the space you've warped this things go a bridge and then you run warp it so that way you don't actually keep by going faster than right you cheat by taking a tunnel through the fabric of space and time end up on the other side of the galaxy during the TV commercial see that's how that works so you get across there in two minutes rather than a hundred thousand years now the nearest galaxy to us big galaxies Andromeda two million light-years away so at the speed of light two million years so we're not going anywhere the distances of space are heat commensurate with the longevity of our biological form so either we find a new understanding of the fabric of space-time or you give up this dream of marrying the fig galaxy okay and I'll leave you with the following consideration I will not preclude the possibility that someone might one day invent a warp drive okay I suppose that could happen and then you warp space and we go anywhere in the universe we want but you know it's cool if you go to a faraway galaxy let's say one that's m100 is the name of the galaxy Hamlet 100 I told you to look up 1087 there's another goddamn 100 it's 65 million light years away you know it's cool right from the asteroid that is making the dinosaurs extinct is only just now we change that galaxy that is awesome so in fact if you read space when through wormhole came out the other side you would have beaten the light you get there in just a few minutes you could go to that galaxy without your telescope and watch the extinction of the dinosaurs that's Time Machine you see things not as they are but as they once were and once you can travel back and forth among them we're in a way traveling in time and I don't know if we're mature enough to make that happen and to not end our civilization in so doing you'll have the Time Lords so I would just be careful about what power you wish for because who knows what will necessarily come of it I'd like to see would be all used for peace and kindness but the people say we want space for one peaceful use of space it stays I don't want anymore and I think this completely unrealistic effect immature I think they'll be plenty of wars in space you know why because we have wars down here on earth right and you can figure out a way to not have gorman space then why did you bring it up here under ok why why you're not going to space some gonna kill each other do that here then I'll have confidence that we can go in space you can find whatever galaxy you want thank you all

In October of last year, scientists found a galaxy 13.1 billion light years away, meaning they can see what the universe looked like when it was only 700 million years old. If a life form in z8_GND_5296 were to look towards Earth, they wouldn't see anything. It will be another 7-8 billion years before Earth would be visible to something that far away.

So does that mean if we can find ways of travelling faster than light, then we could view the earth like this too? For example we fire a satellite that goes really far away, and then use this "new" technology to then view the other as it was years and years ago.

Don't get me wrong, this is hugely farfetch'd, but a hugely interesting subject!

Step one: teleport to M-100

Step two: wait 65 million years

Step three: find out if there was a guy on the grassy knoll.

M100 checking in, can confirm. Dinosaurs are getting fubar'd right this second, in real time.

[u/Reubarbarian]

So...it's 65 million light years away? ;)

[u/Fannybuns]

Wow that's like 1/500 the way to the furthest visible galaxy!

[u/terrymr]

Did anybody else think galaxy m100 was a samsung product for a minute ?

[u/Bomil]

Yeah M100 will take a long way, we're just at galaxy S5 right now

[u/imnotmarvin]

So reversing the perspective, it's possible this galaxy no longer exists, right?
