The universe encompasses all that exist. To say there is
something outside the universe is a contradiction to the
definition of the universe. There are things outside only the
observable universe.

Another thing I try not to think about is what came before infinity, and what comes after and beyond it, in space and time?

I like to sleep at night...

When I was 12 or 13 I had trouble falling asleep trying to figure out time and the universe. I gave up a few years later and started sleeping better. A joint before bed also helped.

In physics, the idea of black holes and the event horizon takes up far more thought. So does Dark Matter and Dark Energy. The topic of the OP is pretty much just philosophical as physicists know they have no way to gain evidence to answer the question.

It's an interesting video though.

The universe came into existence at the beginning of time when
its entropy was at its minimum.

In the big bang model space and energy of the entire universe is
squeezed into one infinitely small point. at time zero.

Evolution of the universe will eventually reach its end at the point of
maximum entropy. At the end of time energy of the entire universe will
have been dissipated; black holes will all have been evaporated by Hawking
radiation; all matter if they still exist will have reached zero temperature.

Nothing came before the beginning of time. Nothing will come after
the end of time.

Except for the other universes.
To the best of my knowledge all evidences so far
point to an undivided universe. Multiverse is a subject
of speculation. Non-observable universe outside the
observable universe belong to the same universe.

What’s outside the universe ?
Isn’t it God?
Many think so. Many don't. I'm a "don't".

Mind you, if I saw a burning bush that wasn't consumed by the flames, and Yahweh spoke to me, I might start to wonder...

Does not that make you think about it even more until you think you solved it then you come out of your stone and laugh at yourself?

I hope I'm not wasting my time in those other universes like I am in this one.

I know I don’t know what’s beyond the void, and how long it’s been around, and what comes after, in a time and spice manner of speaking
I believe we’re a microcosm of a percent on a spec smaller than an atom, and that’s an exaggeration. As the song says, “not here for a long time, so have a good time”.

Religious, fanatical, spiritual, humanist, nihilist, if you live w meaning and purpose, or believe your existence is meaningless and just go through the motions, I believe the bottom line is be cool to everyone, or try; karma’s a bitch.

Thanks OP! One of the better, thought provoking, and hate-less threads in a while.
