A Journey to the End of the Universe

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

  • Guys, I've made an album inspired by your work. Halo Drive concept is so cool and futuristic that I called my last EP Halo Drive. I think you, Mr. Kipping and your team are dancing sometimes, so enjoy! indive.bandcamp.com/album/halo-drive P.S. support with likes, guys, so Cool World team see it! Thanks!

We just have to unlearn what we have learned and give it a crack. Burt Munro from Invercargill would try it.

  • as a phys grad i think people need to realise this... because everyone thinks that the speed of light means you cannot travel great distances within your life time... wrong.... you can due to time dilation :) in fact... you can theoretically travel millions of light years in just a few years or less. !! But i would hope if you ever did do that then within a few centuries you'd be overtaken and met by a few super luminal velocity ships and brought back to earth... rather than finding humanity was gone. strangely though.. this is a general relativistic problem.. and not special,. since its not the velocity difference, but the energy invested or the acceleration that has cause the perm time dilation. This is actually the same as being in a grav field.

  • The point you were making about 100 millennials for humans to come back here. So that means another species perhaps completely different than humans that they have inhabited the earth first could be on that very same objective and could have left around 100 millennial's ago and could return it any moment? Where we've actually went through an extinction and have regressed as far as technology according to their society. That could very well possibly be a scenario correct?

  • Okay, rather depressing, but maybe we have our alternative universes to pop through to. Or maybe our science is more primitive than we give it credit for, and there are other surprises along the way. Remember, we are only 300 years beyond the industrial revolution, when Newtonians thought we had it all sown up, and then came quantum physics. Socrates said knowledge is only a model, or stepping stones to build more knowledge. What next?

  • There's a much bigger picture forming than just 'us' ... We basically are a speck in the scheme of things, a mere wisp of breath, a blip, we are only significant in our own world, which itself is but a tiny drop in a incomprehensibly huge ocean... Not only is their life out there, they are so far away they will never know if our existence, and the same will go for them with other life, and so it will go on..... We are but a single heart beat, a faint miniscule blip on a radar....our entire existence is no more than a single beat of a pulse. So live life....stop wasting it. Everything you do, no matter how great here, means zilch in the scheme if things... We are but dust. Right, pizza and a beer, playstation and a bucket of ice cream it is then. :-)
