Time, death and the universe

[thir]

According to Hawking, though, black holes do NOT remain. They eventually evaporate. I don't claim to understand the physics, but there is one thing that does escape a black hole: gravity.

The biggest known concentration of stuff just evaporates?

But we already know that energy cannot be lost to the material world. It can be changed and dispersed, but not lost.

And so I cannot understand how the universe (or anything else) ran 'run down' ?

Try this.
Still pretty hypothetical, but Hawking radiation has been observed.

Imagine striking a match in a large room. The heat around that match is pretty high, enough to burn you. As the match burns out the heat dissipates. Eventually, the infrared radiation will spread throughout the room, leaving the same amount of energy, but spread over a far larger volume. Pretty much the same as the universe. The energy remains, just much more spread out.

As I understood the theory, they meant no energy left. This is what is so weird.

That doesn't sound right. There would be no FREE (as in usable) energy left. All energy would be bound up in small particles of matter, which would require an input of energy to release, or spread out so thinly throughout the universe so as to be useless. A homeopathic universe, if you will!

there is no time ... time is something we've created to measure the years we live cause we are scared of death .and we think death is the end .
so no there is no such thing as time . we separate day from the night , we separate our hours in a day . we think those are different because we are doing something different .

I think death is just a beginning . I believe we all are one . in different bodies . but our souls are pieces of a big puzzle one united ball of energy called Universe.
not just us humans we all are one as In the Universe and we are one we all are part of it . we are universe in a shape of a human when we die we dont actually die we go back to our basic form . we reunited with what were were once . and I think our souls keep coming back until they are complete . until they learned that everything is nothing ...

As for what started the Universe .... I dotn think anyone knows but I have myh own theory that The Universe is unlimited there is no end nor no start to it . It always have been here and always will be . I know believing this theory is hard cause we have a tendency to find things starts and ends because out minds are limited its trapped in a bone shaped skull . we know there are other planets except for ours but what happens to them do they stop existing after a certain point > then after that what will it just be space ? still space is something so you know what I mean when I say Unlimited ?

A rather simplistic view. What you're talking about is a construct of humans, yes, but time is a fundamental part of the universe. How we measure time is not. And we measure it, not to mark the hours to death, but to regulate our lives, so we know when to plant, when to harvest, when to hunt (the earliest developments of measurement).

so no there is no such thing as time . we separate day from the night , we separate our hours in a day . we think those are different because we are doing something different .

We are doing different things because there are certain things you cannot do during certain times of day. Though with artificial lighting, those differences have become much smaller.

I think death is just a beginning . I believe we all are one . in different bodies . but our souls are pieces of a big puzzle one united ball of energy called Universe.

Nice thoughts, and you're entitled to your beliefs, but do you have any evidence of this? For starters, I'd love to see evidence for the existence of the soul. Mankind has been searching for that since - well, since the beginning of time!

we all are one as In the Universe and we are one we all are part of it . we are universe in a shape of a human when we die we dont actually die we go back to our basic form .

Well, in some sense you are almost right. We are all made from the same materials, and many those materials were once joined in the center of a star, so technically we are a part of that star. And when we die our bodies will revert to those component atoms and molecules again. But believe me, we'll be dead.

I think our souls keep coming back until they are complete .

Complete how? And again, evidence for these souls?

As for what started the Universe .... I dotn think anyone knows but I have myh own theory that The Universe is unlimited there is no end nor no start to it . It always have been here and always will be .

Well, we can agree here, at least. Except that the universe as we know it now did have a beginning (the Big Bang) and, as near as we can tell, will have an end (heat death), but there is no telling what other universes may be out there, or whether all that makes up this universe will merge with those other universes, somehow.

(our) minds are limited its trapped in a bone shaped skull .

Without that skull it's doubtful we would even have minds. Getting into really deep metaphysics here, but our minds are an emergent property of our brains. Without the skull, it's doubtful our brains would be able to develop sufficiently to produce what we think of as mind.

we know there are other planets except for ours but what happens to them do they stop existing after a certain point

Some of the planets in our Solar System will be absorbed into the Sun when it expands into a red giant. Others may wind up being either sucked in or pushed away, doomed to wander between the stars. But eventually, many trillions of years into the future, the universe as we know it will probably be a cold, dead, expanding cloud of dust and debris, expanding into infinity, with nothing to show that it was ever more than that.

Yes your right but I'm not talking about science here you want scientific facts and evidence I can not give you that but as for the evidence for our souls .... I don't know if you've ever heard about astrology and out of the body experiences and how you can be in different places at once . I have experienced this and I still do . Or your past life and who you were before . I can't say here are the evidence you are looking for and for this reason they exist but you can experience them yourself to see that not everything is based on evidence something's you have to feel and touch .

After seeing this thread revived after two years, I had to go back and reread all of the comments. I'm amazed at how intelligent (and how stupid, sometimes) I sounded back then.

I've missed these kinds of discussions. They seem to have dried up since the Big Crash.
