Re: The ultimate q.
 

How do you find the end of a circle? I think that the universe is circular in shape, so that rather than hitting "the end", you just keep going.

It cant possibly just end. Space is not a liquid, solid, or even really a gas, so over time and a distance, it doesn't just thin out and disipate.

Too bad we will never know. It would be interesting to place bets on who is right ;)

Re: The ultimate q.
 

Well, the problem I have with the circle theory is that you usually need at least one point outside of the circle before you can think about one.

Re: The ultimate q.
 

What do you mean by this?

Also, each Galaxy (which there are millions of) are flying around the universe (this being the big sphere thing)!? In between these Galaxies there (put simply) is nothing!

Just as there is nothing between the Earth and the Moon, that is what would be between Galaxies, just in a bigger space and lasting longer. Anyway, getting back to a previous point. If the 'universe' is expanding, that does not answer the fact as to why the stars in the sky are disappearing. it's the universe expanding, not the galaxy.

Re: The ultimate q.
 

I meant that to imagine a circle you need a two-dimensional space with one central point and several points which have the same distance to that central point. If the Universe is a circle, where is it's central point and all the rest of the two-dimensional space which usually surrounds a circle?

I'm not sure what you mean with disappearing stars at the sky.

Re: The ultimate q.
 

The centre point would be in the middle... Would it not!?

Scientists believe that the universe is growing, their proof of this is that the Stars in the night sky are slowly disappearing, thus proof that the universe is expanding.

However, the starts we see at night, are not that of other galaxies, but that of other Suns in other solar systems.

Re: The ultimate q.
 

I think the point Ash is trying to make that if the univeres is expanding, as if we are on a converybelt, with everything moving furthur away from the start but staying the same distance from one object to another eg. the earth and a star. They would both be moving away from the centre of the universe at the same rate so why would the star appear to get furthur away?

The answer to this is that is gravity, gravity of our solar system keeps it together, the earth (and other planets) stays the same distance from the sun becuse they are all constant masses (well not quite but close enough during our lifetimes). However other galaxies or solar systems are not bound by our sun's gravitational pull so after the intial bang they have accelerated away from the starting point, as have we but a different mass affects our speed. Basically anything within the gravitation field of an object will stay the same distance relative to it but things outside this gravtional field will not.

Re: The ultimate q.
 

I don't think we will ever have the technical knowledge to figure out the true answer to this question. However, there are some that might say that if the universe is endless, we are the center. This would be true if everything went on for an infinite amount of time in every direction.

Next time someone asks you if you are the center of the universe, you can tell them, "Of course!"

Re: The ultimate q.
 

This I did think of, however would not have thought it an effect on our galaxy. The black hole in the centre of our galaxy is keeping all Suns at a rotation, these Suns keeping the planets, and planets keeping the moons.

I could not figure out what effect the growth of the Universe would have on a Single Galaxy.

Something from the past? it is a well known fact that we are not in the centre of the Universe as we know it. This was a belief at some point in humanity, though no longer.

Re: The ultimate q.
 

If the universe is endless, everything is the center.

Re: The ultimate q.
 

Essentialy, if there were nothing outside of the universe, it would just be apart of the universe as open space. Beyonde this dimension there is another dimension, another possibility. We are one possibility, in an array of infinite others. We see a fraction of the world, one possibility, where the dice roll an 11 here they roll a 7 in another possibility. So beyond this fraction is the next. This makes up the multiverse, the sum of possibility. It is possible that our multiverse is but a fraction of a larger mass, and thus is a possibility. In theory this could result in multiversal bonding chains and supermolecules, and since that is a possibility then that possibility is may or may not me true in this universe, but in this or another multiverse it may be true. But then again if this is possible then really, all things are possible in one way or another and this chains and groupings go on infinitely building structures, the basis of the atom even and thus the beginning and end are the same, Alpha and Omega. The endless angles and projections of the infinite shape, the sphere, from which all things are built and all things end. Possibility Infinite- Jacques Heyer
