I'm not a scientist or astrophysicist but i do believe in science, is it ok to believe that we as humans and all our scientific development still very very far from proving anything remotely close to how the universe got created? I feel this subject is for humanity in year 2600 to start discussing it. Scientist still can show their theories and search papers and i can't understand a shit but i don't believe in any th…

It's not about belief, it's about observing, collecting data & evidence, and proposing possible explanations. As new observations and evidence are found the possible explanations are refined. No one credible is claiming hard proof of anything at this point.

Agreed, people often mix that up, but you have to adopt a probabilistic mindset, you can believe the coin with land on its head, but you also know that based on the weight and curvature of the coin it will land on its tail 68% of the time you flip it, etc. Then choosing tail is no longer a belief, it is simply going with the choice that is backed by prior observation, experiments, models, etc.

You might still lose, and so you might choose to also believe it will land on tail this time, but the rationale for choosing tail was not based on a belief system, but the going information and where it points too.

I think it's neat that this summary is written by an author of the scientific manuscript. Oversimplification is a risk, but this approach eliminates the possibility that the writer did not understand the underlying science.

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.

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.

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.

So many books, so little time...

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…

That is a very interesting idea… the equation and its assumptions doesn’t seem to have any exceptions so it does strongly suggest our universe is a black hole, inside a black hole?

Earlier quoted context omitted.

Might as well believe in God if you’re going to believe in spontaneous accidental creation…

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.

> The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. It is indeed "often described" in the media as such. However, that is _not_ the currently accepted theory. "What if there were no space and time before the Big Bang" is just Stephen Hawking's pet theory.

You're confusing belief with accepting the current scientific consensus.

Belief is acting as if something, for which no evidence has been given, is true. Imagination, taken too far. No one is telling you to believe anything here, they're suggesting we search for clues to support or disprove a theory. Or don't, it's up to you.

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

I remember that, and the enormous plot hole that they could move the thing in a transporter!
