The end of everything

[Owen The Wise]

Hello all, Here is a rather depressing realization I came to one day in class

Alright so every thing on earth that is alive gets its energy from the sun (excluding ocean vents and molecular splitting, Im just saying like how plants convert sunlight and animals eat plants etc.)
So the sun is the main source of energy in our solar system, and releases its energy in the form of light, and heat(and all that other stuff). Organisms use the energy and then release it back into space as heat when carrying out activities in order to sustain life. This leads up to my main point. Energy is basically always moving from higher concentrations to lower concentrations, until it would eventually be evenly dispersed around the universe, possible in a form that could not be used to sustain life anywhere.

Now I realize this wouldnt happen for an unfathomable amount of time, but one the basic laws of physics is energy can not be created or destroyed, only changed in forms. So if Humans do exist for all eternity lets say, wouldnt are race be eventually destroyed because of the inabality to create energy to sustain any life?

(I am not the educated about everything such as advanced physics. I just completed high school biology. The main point is well run out of energy)

Which leads me to wonder, Say everything goes right, and we dont kill ourselves all or become extinct by some act of nature. No matter what happens, Are race is bascially doomed. No matter what we do in our life times, eventually no one will look back at it and nothing would care.

Food for thought eh?

Yep. This scenario is known as the Heat Death scenario.

It's not for a looong time though.

[Owen The Wise]

And here I thought I was being so original

Well now I know what to call it for future cases

thanks for the link

Well, it's pretty good to come up with that without having had thermodynamics.

[Owen The Wise]

Well energy is behaves like matter, a molecule,and after being drilled with diffusion for 2 semesters I just made a connection

Indeed, diffusion is a classic example of the 2nd law of thermodynamics, the primary culprit behind the heat death scenario and something you'll learn about if you ever do take physics.

Here's a great quote in regards to the 2nd law:

"The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation." — Sir Arthur Stanley Eddington, The Nature of the Physical World (1927)

Take joy in the holy darkness that is to come; Our oblivion will be the only mercy we are given.

[Ulyaoth]

Yeah, it's the common science thing to believe for the end. Personally I don't buy it, just seems as ridiculous as religion in having to believe existence was created and will end. The way I see it it only seems to make sense that eventually whatever force is spreading the galaxy will weaken and we will all compact back into the singularity that becomes the big bang.

[MaximiIian]

Probably a Big Crunch when whatever force that's causing our young universe's rapid expansion (whether it's dark energy or something else, I don't care) runs out, and it starts to fall back inward from massive gravitation. Eventually, it'll coalesce back into a concentrated point, and blast outwards again. Rinse, repeat ad nauseam.

Or the maximum entropy thing. Maybe a combination of both.

[Chaigidel]

Im pretty sure we dont really have a solid idea yet; we have lots of good guesses but who knows what happens between now and then?

[Sebdeas]

We'll all be dead before this happens so it doesn't matter that much

[MaximiIian]

We will be, but we're not sure that humanity won't.

[Ummagumma]

This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang, but with a whimper.

humanity will likely die out as well; that is the hope anyway.

[Amorphos]

i did this idea in the ‘must all things come to an end’ thread.

ah well... i don’t think we can have an end, as it causes the paradox that once you arrive at the end-space then nothing could have ever happened.

down to earth, existence continues, where we see ends are where beginnings exist. we will die as will the world, but there will be other worlds and other lives.

rule; ‘all things must continue’. seams contradictory because nothing stays the same, but a transformation is a form of continuance.

this may or may not be so in personal terms [e.g.with reincarnation], but in universal terms it is.

[MaximiIian]

That's a bit of a twisted viewpoint. Why would you wish your species' destruction? Why not do something to make humanity better?

[Thanatos]

You first, pal. Be an inspirational example, if you think we should all die out so badly.

[Phalanx300]

I don't really believe that the Human race will die out, it might evolve or something but die out?? I doubt it .
