    Any one here thinks that another universe actually exists? I do, for one...Imagine freakish aliens from another universe visiting us...

    I think it's reasonable to think we were not the only 'big bang'... I can not get my head around this being the only thing that exists full stop. If this really was the only big bang, then it worked out miraculously well didn't it?

    As for aliens visiting from other dimensions... I seriously doubt it. I would even suggest that if other dimensions with life existed, that it would be impossible to travel to another universe outside their own space and time.

    I think in the distant future, say the next 200 years or so, we'll be lucky if we get to Alpha Centauri. Even that's pushing it a little for future space travel for humans. Anything beyond that is probably to distant to consider. Aliens visiting us from another universe? I hope there is a gas station in Zeta2 Reticulae

    Space travel is impossible. There will be no technological innovation to prove me wrong. We are stuck in this solar system. I think it's presumptious to think of having technology in any manner 200 years from now. We'll probably be deep in the throes of absolute barbarism by that point. And then probably something catastrophic will happen in x0,000 years and we'll be extinct. At least that's what seems obvious to me.

    I think the Voyager probes disagree with you on this point, so it may be possible to build manned probes to leave our solar system, although we wouldn't see much just outside, so it's rather pointless, and you are kinda right.

    This often comes up, but the only reason it does is because people abuse the word 'Universe'. There cannot be another Universe, because everything that exists, is part of this one. The only way another 'Universe' can exist, is for it to have a completely different set of dimensions, that we cannot interact with. That said, we will never be able to detect said extra Universe, so it will never be more than a hypothetical.

    If there is someway to interact, it is part of _this_ Universe. There really is no way around this.

    I wouldn't be quite so sure. If civilisation keeps progressing, how do you know what technologies we will have or not? Did anyone seriously think that we could go to the moon before the invention of powered flight?

    There could be many methods usable by a seriously technically advanced civilisation...

    It is impossible for man to travel at speeds of over 20 miles per hour
    A heavier than air flying machine will never work
    The atom bomb will never work - I speak as an expert in explosives

    Any of those sound familiar? How good is your knowledge of technology? On the evidence presented here, I'd say limited.

    But I don't believe that man will ever travel faster than the speed of light.
    The claim " Space travel is impossible" is wrong. After all we did go to the moon.

    Wright brothers flew in 1903, the same year Konstantin Tsiolkovsky published "The Exploration of Cosmic Space by Means of Reaction Devices." and Tsiolkovsky had been working on his rocket ideas for some time before publication. Of Course, Jules Verne wrote "From the Earth to the Moon" in 1865, which inspired Tsiolkovsky so yes, people had seriously considered going to the Moon before powered flight was possible.

    Reaction engines, whether rockets or ion drives, have been our only solution for space travel for a very long time, and will be into the future, and so far, there is nothing else on the table.

    Motion is about action and opposite reaction. What else can you use in space but a reaction engine? Therefore we might get better engines, but they will always be reaction engines, and that idea is nothing new or 'seriously technically advanced' really.

    the universe means everything that exists, so there can't be another universe.

    I prefer to use the word multiverse to describe everything that exists. I am sure that most of you have already heard the theory of infinite possibilities. (Everything that can happen will happen) For example, lets go all the way back to the big bang. Not long after the big bang a hydrogen atom could have existed at some point in space in this universe. That atom could have traveled from point A to point B within this universe. In another universe it could have traveled from point A to point C. That minute difference could cause a chain of events that could make the point A to point B universe different from the Point A to point C universe. The laws of physics in some universes could be very different. Try to imagine what existence would be like in a universe of antimatter.

    If existence is a multiverse of infinite possibilities, then it is reasonable to believe that an advance alien race could evolve to a point where they learned to travel to other universes. Some of you may think that the existence of other universes is ridiculous, but some physicists that are working on string theory believe that gravity could be a force in this connected to all of the other universes. It could explain why the force of gravity is so weak compared to electromagnetism. The theory states that the force of electromagnetism is confined to this universe; while the force of gravity is weaken because it is distributed through out the multiverse. BTW, parallel universes are not the same thing as multiple dimensions. You can read more about string theory in the links below.

    As for the debate about us traveling in space, I believe that we have the potential to evolve into gods or we can continue to live like primitive apes. I have no way of knowing what will happen in the future, but I hope that we will use our technology to rid ourselves of our genetic flaws. I hope that we will use our technology to improve our cognitive abilities. I hope that we will evolve into a race / entity that will continue to gather information about the laws of physics within this universe for millions or possibly billions of years. I hope that we will use this information to obtain more control of the space in which we exists. If we do accomplish all of these things, then perhaps one day we will learn how to travel to other universes.

    Yes well, by the same reasoning if worm holes one day prove viable then people will look back and say that the 20th century realized it's potential. But what I mean is that it is still generally inconsiderable by science because there is no such technology to acheive it... Just as there was no such technology in 1865 to attempt a visit to the moon.

    You are still thinking present day technology and current understandings of physics. I don't think we can realistically guess what we will be using to get around Earth and Space if our technology continues to grow uninterrupted for say... the next 10,000 years or so.

    I am a man. This being said I don't think we will evolve into godlike beings in the near future, mainly because any being that could exist wouldn't be godlike since god is not a being.

    Now as for another universe, well... as far as we're concerned this is the only one. I do however think that there can be another universe because in reference to space-time there isn't really a location for this one, and if this one does occupy some sort of area which we are unaware of existing then others can occupy their own as well. Each could be like ripples in a pond with a single mechanism for the bang.

    Anyways, multiverses sound good too. Maybe each possibility is omnipresent, but then again who cares. I mean listen we're all dead now anyway, in 100 years everyone that uses this forum will be ash. The logical conclusion is that consiousness cannot exist without a body, but who will be here to argue when it's dead? So in essence you would be a god, free from your mind.

    The multiverse is pretty much mainstream now. There are infinite universes. Just ask Stephen Hawking. Don't expect to understand what he's saying or anything but trust me he'll agree.

    I was repairing a post the other day on this very topic. If we mere humans can hypothesise on it then surely others have done it. Universes have come and gone. Travelling out of a universe is relatively easy. It's knowing where you'll end up thats hard. I think if a universe was dying then many species would risk a leap into the unknown. Where would they end up?

    Maybe here.

    Are you planing a trip outside of this universe in the near future? Keep us posted.

    Such a useless question. Yes, other universes exist. No you will NEVER have any proof of it. If we are to survive long enough to travel even to the next star system(where we probably can't live anyway),we would have to start conseving all species of life now. The reason is food in the future.

    What makes you so sure other universes exist, if you can never find any proof of that?

    Nothing at all, and there can never be any proof either way. So it's all gut-feeling for anyone to believe either way.
