Can the predicted White Hole (general relativity) exist? If they exist, can they be the "big bang" that expanded energy-matter, light and others?
Neil deGrasse Tyson
In the 1970s, when white holes reached mathematical maturity, we started onlooking for them. Could it the be the quasars that are so small, bright and distant? Might every Black Hole have a white hole connected on the other side, emerging in some other corner of the universe.
None of these ideas found data to support them. Also, the properties of a white hole are clear and present. The early universe does not look like them either. So for now, it's released to science fiction.

Can you explain, if the universe is expanding from the point where the Big Bang occurred, how can the light from the objects (now) X billion light years away just now be reaching us? How did our slow selves physically get "out here" AHEAD of that light, while we wait patiently for it to arrive? In other words, how is the expansion of space faster than light?

In a four dimensional civilization(assuming the fourth dimension is time) would it be possible for lower class citizens to all share the same house at different times? in other words people would not rent their own apartments, they would rent a time slot at a communal apartment and simply commute back or forward to that time slot. Additionally could this concept also be the case for offices?

I've been reading "Project Hail Mary." OK, it's science fiction, but there was a part when a character didn't know anything about relativity and was surprised that he had extra fuel at the end of his relativistic travels. That doesn't seem right. OK, there is time dilation, so the trip doesn't take as long as he thought, but doesn't his mass get bigger as he goes faster--needing more fuel to accelerate his ship?
