We have no theories working at those conditions. Wiki says > General relativity also predicts that the initial state of the universe, at the beginning of the Big Bang, was a singularity of infinite density and temperature.[6][obsolete source] However, classical gravitational theories are not expected to be accurate under these conditions, and a quantum description is likely needed[7]. https://en.wikipedia.org/wiki/Gr…

> [6][obsolete source] I didn't know but apparently wikipedia treats old sources as obsolete, doesn't matter if there's new information or not that would make it obsolete. I wonder if any sources supporting the notion that the earth is round must be updated every couple of years with a new source or study.

Interesting read, but even if we assume the author is correct, and the cosmos formed as a black hole in a larger universe, the question remains, how did this larger universe formed, then? Might just be impossible to know.

It’s turtles all the way down

Black holes all the way up.

Am omnipotent being is a necessity for making observations. A lot of religions considers consciousness as God.

I don't see how this is. It seems eminently reasonable that observation can simply be performed by sub-omnipotent beings.

Life is one omnipotent being. It's just ego, thoughts and social identity that creates the illusion of multiple beings.

But ego and names are made up. Separation just thoughts. The more life believes in thoughts it becomes divided.

But the waves and ocean are one.

If universes can exist in black holes and obviously black holes exist in universes, doesn't that smell like infinite recursion?

What reason do we have to believe that every universe can support black holes? We only have a sample size of 1 here.

What reason do we have to believe that there is more than one universe?

Which God? Vishnu? Ra? Amatarasu?

Assume God exists. Various isolated cultures are going to come up with different names for God. This like saying which Sun? Surya, Ra or Helios? All are different names of sun. But there is only one sun.

On the other hand, there are a lot of stars and different cultures might give them different names and yet there really are many of them.

Furthermore, assume God doesn't exist. Lots of cultures might invent god for various reasons and they'd naturally have different names and attributes for them, which in fact seems to be the current state of affairs.

In fact, if we assume God exists and is actively in communication with humans, its actually a bit weird that different human cultures would have different conceptions and names for that being. Why didn't it just give everyone the same name and information?

Yeah, wow. That was great. His solution seems so simple and clears all the previous model's problems. I guess every black hole could contain its own universe.

Too bad the author didn’t explain more the concept of the “parent” universe and how our own (contracting & expanding) universe got created. Nice things to read/consider/ponder late at night :-)

Unfortunately, it appears that the universe does not care very much about human satisfaction. Fortunately, other humans do.

This brings to mind something I keep thinking about for years (mostly from watching too many physics videos).

- Gravity "slows" the time down, gravitational singularity should bring the time to a halt

- Suppose there is a quantum process that makes the true singularity impossible, so all black holes immediately expand right back

- Looking at it from our time scales, even if the singularity existed for a moment, it would appear that "infinite" time has passed while from the black hole's perspective, the expansion was instantaneous.

- From earth's perspective, if the singularity ever existed in a black hole, it stands to reason that when the time "resumes" from a black hole expansion, it won't fall into any of our known timelines since infinite time would have passed.

Than why do we need a beginning if there was always something.

"beginning" is a misnomer, since time itself started with the Big Bang. There is no such thing as "before" the singularity, as time and space were curved together.

There are many theories that portray time as existing before the big bang.

First define consciousness such that the definition differentiates you from a computer with a webcam.

You cannot define consciousness. You can only experience it. In fact consciousness is the only thing you will ever experience.

Perhaps you should use 'sentience' or something more precise to mean 'qualia-experiencing'. The word 'consciousness' is quite overloaded and thus trips people up who haven't thought about this as extensively as you have. In particular many people take it to mean "self-awareness" (whether correctly or not), but it seems obvious to me that there are many sentient beings which lack self-awareness but still have an internal experience.
