Is the time since the Big Bang the same for every point in our universe?
If so, does that imply there really is a "present" moment everywhere and
not just in my immediate locality?
We keep hearing that "It all started with the Big Bang" and how "Everything was compressed into an infinitely small dot" and suddenly it expanded. Personally, I've wondered if this is more of a misinterpretation of distance, just as the headlights of heavy traffic on the highway looks like a...
Is there a fundamental difference between the (speculative) understanding of a singularity arising from the creation of a black hole and the singularity which we think may have been at the origin of the Big Bang?
Noteably, would there be two basic theoretical types of singularities...
Is there a reason the Big Bang would be a private science (like time travel would be). Is the creation of a universe dangerous? Would there be any reason to this?
Supposing that the total mass + energy content of the Big Bang was 100 in energy-equivalent terms. What would we consider its energy-equivalent mass to be today? If the universe is today accelerating and that acceleration is not abating, then (naïvely perhaps...) its (dark-energy) potential...
This may seem like a naive or obvious question, which is why I posted it here.
How do we know the cosmic microwave background came from the Big Bang? How can we tell how old radiation is?
The big bang supposedly originated from an infinitely dense singularity of space/time. The concept of infinitely dense is an artifact from our current perception of how immense our universe is today and how spread-out space/time is. However, if I were present in the reference frame of that...

It has been proposed by Edward P. Tryon that the Universe may be a large scale quantum mechanical vacuum fluctuation where positive mass-energy is balanced by negative gravitational potential energy, as a consequence of the early inflationary launch of the expansion of the Universe, in which...
As I understand it Georges Lemaître, upon learning about Hubble's discovery that space is expanding, came up with the big bang theory. He thought that if space is getting bigger, then it must have been smaller at one point, and if you go back far enough you get an extremely dense singularity...
Hello,
If the speed of light is the maximum speed limit in our universe, how was the big bang event possible because surely the expansion would have been constrained by the speed of light?
