Perhaps an easier explanation is available, premised in GR. In General Relativity, space is dynamic. It can expand, shrink and curve without being embedded in a higher-dimensional space. In this sense, the universe is self-contained. It needs neither a center to expand away from nor empty...

Perhaps we can offer an easier explanation. Using the most powerful telescopes, we are capable of observing galaxies 10 to 13 billion light years away. But the "horizon" of visibility in the cosmos streches more than just some 20 to 26 billion light years because space itself is expanding. So...

I would like to propose another possibility. Perhaps a long established law of physics may be extended to construct a rudimentary pre-Big Bang cosmology. This principle to which I refer is the law of the conservation of mass-energy. If mass-energy cannot be created or destroyed, and if the...

Kudos to you, gentlemen. You have certainly provided me with a better understanding. Chalnoth, I believe the distance for galaxy formation is about 13.2 bly, and therefore created when the universe was only about 500 million years old. I just have to throw one more inane one out. My high...

Hello everyone! I'm new to the board, so thought I'd take a moment and introduce myself. I have a degree in Liberal Arts, but like so many of us, the first time I gazed upward on a dark night and wondered in amazement, I was hooked. I have enjoyed perusing so many of your contributions, and...
