Chronos: I agree with you completely. An expanding universe could not be infinite. That makes a lot of sense to me. Also, the way I see it, the big bang really should be called the "big expansion." The universe was once a finite singularity, and to me, it still is a finite singularity...

Hi Radrook, My original thinking is that in a finite universe, the boundaries at its edges, would serve as markers by which every moving object's speed, in such universe, would be relative to the "boundaries." In other words, each object's position would be special, in relation to the...

Collinsmark, That is an amazing brief on relativity in regard to light. Amazing to me, but perhaps mundane to you folks of the high digit IQ variety! Thank you for taking the time. I shall cut and paste that into my personal notes. I am not studying toward a degree in astrophysics, but merely...

Oh, and Collinsmark- if the Big Bang happened everywhere, then it stands to reason that the universe is still a singularity, just a larger singularity.

Collinsmark, Thanks you for such a well thought-out reply. Interesting, the notion that the big bang happened everywhere. I can comprehend that. I think by referring to the big bang as a big "expansion" rather than a violent bomb-like explosion, it's easy to understand that our known universe...

That makes sense to me. Good explanation. Okay, so let's forget about open or closed universe for a moment and stick with the idea that no matter what, there are no 'special' markers, start or stop points. I still can't get my head around the idea that speed can be measured without a...

I say it is finite. That is, if we agree that the speed of light is constant irrespective of its surroundings. Let me explain what I mean. A car traveling 60 mph is only doing so relative to its surroundings on earth, such as trees and homes along the roadside. But what if the car had no...

I think my above post is straying from the original topic. I'm going to start a new thread with it.

Good clarification. I recall learning that before, but had forgotten. That suggests that speed is not relative to nearby objects, but is relative to the entire fabric of the universe, which suggests that the universe is finite. Let me explain what I mean. A car traveling 60 mph is only...

If time is faster closer to the sun, then why would you not age slower the further you go from the sun? And if you kept going, eventually reaching the void of absolute space, outside the influence of any star, then would you not stop aging altogether?

That's interesting. I guess it's in line with how jets at high altitude (hence, further from the earth) will lose a second or so on their clock. Just thinking out loud here, I could be off my rocker, but I wonder if that means that time may come to a stop altogether for an object drifting...

No. Gravitational pull is governed by mass, not density. Earth is far more dense than Jupiter. But Jupiter's greater mass makes its gravitational pull much stronger.

Do I believe there is life elsewhere in the cosmos? Absolutely. Do I think they have radio, nuclear fission, space-faring vessels and maybe even technology far beyond our comprehension? Yes, but they are likely so rare, it's inconceivable that we will ever cross paths. Why? For...
