Too finite to understand... But of the infinite essence to apprehend?
I love the cosmic very much, so as the theories and hypothesis of recent cosmology.
Is the universe infinite or eternal? No one can tell.
Or both?
About the eternity of the cosmos...
Physicists believe that protons and electrons are the most stable things. Normally, they don't think they will decay. But if they really will decay one day, this physical universe will have an end.In some grand unified theories, physicists propose protons will decay, and various experiments and observations are carrying out in many places of the world. But, to date, all attempts to observe these events have failed....If one day "proton decay" would be observed, that means the universe will not last eternally.
About the eternity of the cosmos...some cosmologists propose that the shape of the universe is closed, while others think it is open. If it is closed, sooner or later it will change from expansion to contraction, and eventually becomes a point, just like the state in the beginning. If the universe is open, it will continue to expand until infinity...some say these.
Multiple universes...if so, it would be interesting! Some cosmologists says there was only one universe originally, since it started expanding rapidly, phase transitions occured in its interior and many bubble-like spaces were formed, and eventually they divided into more and more "bubbles", just like cell division. I'd really like to think one "bubble" is an independent universe, yeah, and have no frame of reference outside themselves. And no fixed dimensions, you say?
