Heat Death Of The Universe And Other Cosmic Extinctions.

Threads I don’t read? Which ones?

Who said anything about nothingness? I did say something on the lines of nothing matters in the big scheme of things. That’s about it.

No, I was speaking about the destruction of the universe and everything in it. Hardly entails nothingness. Please try again.

Joker, don’t be a fool.

The Fool.
Aka the Joker.

Joker, reason being is they want to make tech so they can escape the sun exploding. After 5 billion years of tech, they will figure out how to escape the heat-death as well. Most Life-forms have inherent instincts of self-preservation.

For example:
The Absolute Impossibility of Nothingness - Ever

Well okay. You then mean the theory that the entire universe would become merely a field of EMR (uniform “Affectance”). That too is entirely impossible because particles and black holes spontaneously form as depicted below:

No tech is going to stop the sun from going red giant when it does. And nothing can survive heat death. There will
be no stars to generate light or heat and the temperature could be only a fraction of a degree above absolute zero

And the reason that heat death can never actually occur is the following eternal, unavoidable process:

Bob, its about moving to other regions of space.

Bob, it’s about creating machines to generate our own heat.

That part would be largely true, but…

… that part isn’t an option.

Nice videos. Well done.

Looks like we still have a lot of exploring to do :stuck_out_tongue:

Thank you. They still run a little fast and you really have to see all of it to fully understand how it all fits together, but … gotta start sumrs.

Does this “boil” down to God not being able to off himself?

The most popular view among physicists is that the universe goes through a cyclical phase of every Big Bang being
followed by a Big Crunch and so on. And so while heat death can last for a very long time it is not actually infinite

Einstein, among many others disagree. But one serious issue is that such would imply a center to the universe. And that implies an absolute frame of reference, which refutes Relativity entirely.


There are other models : The Big Rip - The Big Freeze - Death Bubbles

All bogus.

The universe merely keeps changing as if an infinitely large cloud of black holes and galaxies absorbing each other, exploding, drifting, reforming, on and on, never larger nor smaller.

What happens when maximum entropy has been reached and there
is therefore insufficient energy available to perform any more work

Also once black holes stop absorbing matter they evaporate into radiation
They do not carry on expanding forever. That would be a violation of entropy

“The Law of Entropy” is not THE LAW.

Black holes would grow until all floating matter surrounding them was absorbed and then, if not sooner, they migrate toward each other gaining speed. When they eventually collide, they create more galaxies in a different location. Of course, they don’t all have the same timing, so some are still growing when others impact them.

The free radiation that they emit doesn’t make up for all of the matter they absorb (obviously, else they wouldn’t grow).

Dark energy is causing the space between galaxies to expand away from
each other in all directions so black hole collisions are far less probable

No. It is causing it to appear that way because light bends while going through uneven “dark matter” as well as gaining more red shift. You can’t tell how far things are apart merely by looking at them, nor simply by measuring from year to year.

Specifically, the galaxies cause a depletion of the matter between each other. And that causes a thinning of the energy/matter in those regions. The effect of that is that they appear to be further apart as the light is less and less affected. But eventually, they gain no more mass and merely drift toward each other. Actually they were always slightly drifting toward each other as they were absorbing matter.

And that is why you see some black holes spinning around each other and some merely drifting through space.

Particle physics. Ah the reason scientists tend to be androgynous. Its the notion of being surrounded by balls.
