The Universe we know and love - with Einstein's General Relativity as our theory of gravity and quantum field theories of the other three forces - has a problem that we don't often talk about: it's incomplete, and we know it. Einstein's theory on its own is just fine, describing how matter-and-energy relate to the curvature of space-and-time. Quantum field theories on their own are fine as well, describing how particles interact and experience forces. Normally, the quantum field theory calculations are done in flat space, where spacetime isn't curved. We can do them in the curved space described by Einstein's theory of gravity as well (although they're harder - but not impossible - to do), which is known as semi-classical gravity. This is how we calculate things like Hawking radiation and black hole decay.

There is still much we don’t know!
If absolutes are a problem for you.
That is an understatement.
Simple answer...Get a big enough ball of string and it makes its own gravity.
David Bohms holographic universe. The observed evidence points this direction. Many have trouble dealing with its implications. Don’t ask me any more. There are probably less than two handfuls on the planet that can halfway grasp its implications. ( David Bohm was Einsteins protege at Princeton)
Black hole decay.
obama. Unprotected sex. Just sayin'...
Back in the 80s, I remember talking to a physics professor along with a fellow student. As I recall, our Dr. Wersinger talked about the possibility of time being quantized and how it would mean that calculus wouldn’t be quite right since calculus assumed a continuum.
Knock knock knock Penny. Knock knock knock Penny. Knock knock knock Penny.
NERDS!
Numerical approximation is a Good Thing.
What I’d like to know is...
with all the countless stars, all the planets, all the inhabited planets, all the intelligent life that should be in the universe, how come nobody has blown it up yet?
Who is always standing by to say, “Hold on there buddy, you don’t want to touch that switch.”
I could go in to detail, bit I don’t want to hog the thread.
