Suggested hard sci-fi light reading: "Cosm" by Gregory Benford, 1999. A universe the size of a bowling ball created in a laboratory. The scientist responsible for it, keeping it safe and on the run from gvt spooks. They want to protect it for as long as it lasts, and since its time is as relative as its size, they won't have long to wait.

Rick and Morty episode (season 2 episode 6, 'The Ricks Must be Crazy') where it turns out rick has created a whole universe inside his spaceship battery who's whole purpose is to produce energy to run his spaceship. A scientist within this microverse creates a miniverse ....

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.

But who would be as cruel to put us here without giving us those answers? Who? And where did that entity come from?

Maybe there was no cruelty, and we were just plain matter that fell into our encapsulating black hole. Like what happenswith our own universes black holes.

Cool article!

I can hear Sean Carrol saying, though, that:

1. We know general relativity isn’t complete, because it doesn’t take quantum mechanics into account.

2. We can’t say whether this is right because we don’t know the quantum theory of gravity.

But I don’t actually know what I’m talking about.

Big bang theory no longer excites me. As long as we can't explain consciousness all these theories are pointless. All theories mere appearances in consciousness including the universe and everything we experience. Consciousness has the property to render infinite universes and theories. But we have no clue how universe creates consciousness.

Consciousness is a specific biological adaptation which is primarily focused in the management of social relationships, status, and the prolonged adolescence of children. (and their required care) There's no reason to think that consciousness is an important question in the objective sense; it just matters to people. (and rightfully so) People wondering about consciousness in the universe might be akin to dogs wonder…

Are we both talking about the same thing?

Oh I have so many questions on this topic. I've often wondered about this. I don't have any direct physics training, but it's something that felt really plausible after I learned that the mass of a black hole is linearly proportional to its swarzschild radius. As the size of the black hole goes up, its overall density must decrease. Combined with the other observation that our universe has uniform density at large sc…

You really want to be thinking about this in terms of entropy and not matter.

Arguing semantics is rather boring when it's obvious you understood the point he was trying to make.

None of that precludes uniform density at large scales.

Added. Opinions: A) I love all the scifi book recommendations that cone up on HN B) i wish you’d all stop recommending great and amazing books. My queue is so backlogged and jammed I'm never going to catch up.

Same here. My interest in the Sci-Fi genre started with an HN comment recommending Blindsight, by Peter Watts.

Several comments and sci-fi series later, and I’m currently reading about spacefaring sentient spiders.

Earlier quoted context omitted.

You can measure various aspects of a computer. You can't measure consciousness.

That's not a definition. Depending on the definition, it may be possible to measure it.

You cannot measure consciousness. You are consciousness thinking of itself as the human. Measurement is an event appearing in consciousness done by humans.

It's like persons inside GTA talking about measuring the Samsung monitor. It makes no sense cause they can never see the monitor or locate it. They appear in the monitor.

I sympathize with Lee Smoolin's cosmological natural selection hypothesis, which would require that black holes give birth to new universes within

I seem to remember a similar Star Trek episode; DS9, IIRC.

So many books, so little time...

If only we had an even bigger universe, we would have more time... is that how it works?
