The most mind blowing problem in all of physics

[xmontrealer]

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.


This kid has one of the best mottos for
“L-I-v-I-n”:

I read somewhere that the odds of one of us being a human on earth, out of all the matter in the universe, is something like 1 in 400 quadrillion or more.

Someone likened it to the the odds of flipping a quarter in the air and having it land on its edge, and stay upright, 100 times in a row. Well, at least that's what that person said lol...

This sounds like SPs trying to explain their various STD safety protocols.

A lot of the right words but mixed up in a blender.

Or infinity will occur after the end of time.

You may argue there is no end of time in which case infinity
will occur. But if you accept time is to end at some point in the
future then there is no infinity to follow.

But how can time possibly end?

Time flow in the direction of entropy.

At least for a finite universe entropy cannot be
infinite. Time reaches its end at the point when
entropy of a finite universe has increased to its limit.

The odds of a God coming out of nowhere to create a human
on earth is even higher than that.

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 is on the other side of a Black Hole?

 

[shack]

This sounds like SPs trying to explain their various STD safety protocols.

More like explaining their rate structures. Like how a 1 1/2 hour booking cost is a higher rate than a 1 hour rate.

will occur. But if you accept time is to end at some point in the
future then there is no infinity to follow.

I am of the "there is no end of time" philosophy.

 

[shack]

What is on the other side of a Black Hole?

I was going to say white hole, but I think that pink hole is a better answer.

 

[oil&gas]

What is on the other side of a Black Hole?

Try this thought experiment.

You were space-walking in interstellar space. A massive black hole
came out of nowhere into your vicinity. You were getting pulled into
the black hole.

There are two possible outcomes.

You either

a) became of nothing

or

b) emerge from the other side of the black hole to land in
another universe.


Gravitational force of the black hole would be so
strong you would be ripped into pieces well before
you reach the event horizon. By the time you
are absorbed into the black hole not even any
atoms of your body would remain intact.

As such outcome b seems extremely improbable.

 

[oil&gas]

I am of the "there is no end of time" philosophy.

The universe appears to be finite. I would look to
scientific evidence not philosophy to decided what
the more probable answer is.

 

[Adamxx]

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.

vKindly explain your perception of what time is, and when it began, what cased it , and what will be cause of the end of time.

In your mind, is time a constant or relative, or only a means of measuring the existence of something which can be “observed” or “measured”.

 

[oil&gas]

At the beginning all the energy of the entire universe was contained in an
infinitely small volume of space. If there was a cause of the beginning of
time just convince yourself it is implausible for time to stay frozen at time zero.

That point of infinitely small volume had to explode for the energy contained
to transform into matter and to drive expansion of the universe. If the
amount of energy trapped at time zero was finite time has to end at the point
when all energy is dissipated and all matters reach the end of their lifespan.

 

[Massivo]

Philosophy has wrestled with this question from the very beginning...Then Ludwig Wittgenstein came along and said there are limits to what language can express. Inter alia, language cannot express the unfathomable. I think this is one of those things language has difficulties with and when we try to answer the question, we run into paradoxes...

 

[shack]

At the beginning

When was this beginning? And what was there before?

You talk about the energy in the beginning. Where did it come from if there was no universe? And how did it enter into the universe? Did it appear all at once or did it build gradually.

They say that the amount of energy in the universe is a constant. It's a sum zero situation which must bring up other paradoxes when discussing how the universe acquired this energy..

amount of energy trapped at time zero was finite time has to end at the point
when all energy is dissipated and all matters reach the end of their lifespan.

Can such a point exist without the empty space that contains it, and are there other points packed with similar energy
and waiting to explode when the time is right?

 

[oil&gas]

It is inconceivable something else other than space can exist while
space itself is non-existant. In the absence of space neither time or
matter can exist.

The volume of space that contains all the energy of the universe
at time zero is all the space of the universe. That point wasn't
suspended in space. When that point exploded to kick start
the beginning of time it wasn't exploding into space. To this day
expansion of the universe since the big began isn't an expansion
into space outside the universe. It is an expansion of the univese
into the universe itself.

Things become tricky at the end of the lifespan of the Universe when
all energy is dissipated and all matter disintegrated.

All that remain will be subatomic particles, protons (only if proton
does not decay which is not certain), free photons in a vast space
of darkness.

I presume death of the universe marks the end of time unless the
supreme being creates an alarm clock that keeps ticking into time
infinity on his throne.

Actually understanding the end of time is more tricky than time zero.
According to certain model quantum tunneling will not die down entirely
at the end of the universe. So in a sense time will continue flowing with
no end or until the universe is resurrected.

The universe is as infinite as human stupidity.
