The prospect of interstellar travel is no longer sci-fi. It COULD be achievable within our lifetime! But, how would an interstellar rocket-ship work? On this week’s episode of Space Time, Matt talks options for interstellar travel – from traditional rocket fuel to antimatter drives, could we travel to other star systems? Watch this episode of Space Time to find out!

  1. Of course you are mentioning Alpha Cen a lot on this video which is making me think Alpha Centuri which is actually a whole different galaxy……………..so I have knowledge of! So why travel to a different galaxy when there are more solar systems in our own galaxy to explore right here to start with? After all we can't see what is 180 degrees around our own galaxy and who knows what planets are hiding out of phase with our own solar system within our own galaxy, to begin with! Heck we don't even know what older solar systems lie in wait between us and the super massive black hole in the very center of our galaxy either for that matter as well! Who knows maybe only 30 light years away is the planet Vulcan in that case, because we have only been able to "observe" a very tiny slice of the night sky in our own neighborhood to be totally honest here, and even the whole mass of our own galaxy has billions upon billions of stars without ever even leaving our galaxy to try to explore as well that nobody ever seems to really talk about!! And instead of jumping to theory about traveling to a distant galaxy first, lets just try getting across the street as it we to begin with in our own Milky Way!

  2. I like the fact that alpha cen is 4.4 light years away but an astronaut going at 0.8 of the speed of light would experience a 3.3 years trip. Crazy to think about.

  3. I think pulsed fusion offer the best story for humanity, us repurposing our most awesome ad awful creation for exploration. plus the inevitable alien contact "are those fucking mammals shooting bombs out their ass?"

  4. You got to stop thinking about travel as a need to move matter across these distances. Information can be moved some day once someone figures it out from quantum processes instantly . And information or knowledge not solid stuff is reality, . ideas like worm holes , have a much better chance .

  5. I think the solar sail will fail at some point.. cause when it leaves our solar system, our moon will keep on orbiting around the sun and maybe swirl away from the solar sail…

  6. Man, we live in awesome times! I love hearing about this stuff. I tell my sons all the time that they are growing up in a totally different world than I did. The future REALLY is now, but just imagine how much different it'll be in 30 years.

  7. why do we need to visit alpha centuary ourselves ?? we may shoot concentrated high power gamma rays at every corner of the alpha centuary, and map the terrain by looking at the light thats reflected back towards us in
    earth / the space station.

    I am talking about active telescopes, which work like a radar . Our current telescopes are passive and they capture only the existing natural stimuli . We must artificially enlighten the object of interest in space. Once we enlighten them, we may get to know more stuff, that will let us design our future inter space travel vehicle.

  8. it's always about "money" it's the bane of our existence while being nothing more than a retarded religion. we have the resources, we have the people, we have the motivation, we have a lot of knowledge to accomplish these things. but we all buy into this religious bs that you need "money" to do anything. THIS IS SO PRIMITIVE. civilization my a55…. over 7billion controlled by at most, a few hundred cult leaders. in a resource based economy we'd already be on our way to the stars. in this anti-economy we have going on, we'll go nowhere – ever

  9. Problem that I see with these scenarios is that the G-Force on the occupants of the rocket ship would likely be too great. I have not done the math (I know how, but my disability makes it a risky proposition). Getting to 0.5 c in a few months (10^8 m/s) would require a rather fast acceleration (ditto with any other discernable fraction of c).
