Who cares how short you live. A person who lived 30 years of quality life (eg: ran for president, became a billionaire, did something for the world etc) is exponentially better than a normal faggot who lives up to 80 (wagecuck).

Time is decay. Time is the byproduct of decay in a process of energy going from highest concentration to the lowest concentration.
This decay affects everything. including space. Space expands as energy inverts. And since all matter and energy has a setting from highest concentration to zero, all things in the universe are subject to interacting and moving in this blank void.

after the heat death of the universe, everything will just be motionless and turn to nothing.

This is what normalfaggots think. What do you think happened after the big bang? Yes, it was also motionless and nothing. If the heat death does occur, another bigbang will happen and the rest of our lives will repeat. It is a never ending cycle.

It's an illusion. The future, past and present all exist at once.

>>9756115
But if they exist at once why do we perceive only one time instead of all times?

>>9756881
Nobody knows.

I'm assume your question is limited to physics as you are posting this on /sci/. Time is just a parameter that let's you register events. That is time is a pure kinematic concept and is independent of whatever physical theory you are using as it's just a way to differentiate between events.

>>9756039
they both amount to nothing

.....No. How did you concentrate the entire universe into a singularity after it’s been spread as thin as possible you fucking retard?

>>9756030
There is no such thing as time there is only cause and effect. We invented time as a way to measure some cause and effect scenarios.

>>9756030
A unit of measurement characterized by the moments between the passing of the sun.

What's the time?

>>9757154
Maybe the force pushing the universe apart will grow weaker than gravity at some point

>>9756030
It's how we apes take note of entropy/

I believe time to be an expression of the dielectric and magnetic field.

>>9756030
Time is the effect of the clock created by massless particles traveling at the speed of light, trapped in groups of interactions incapable of doing so as a whole due to the mass they create in that interactive process. This leads to measurable entropy, and eventually, perspective to measure it with.

As for why we perceive time the way we do, fuck if I know - probably something about all having developed in the same gravity well, and it's "good enough".

Maybe more of a >>>/lit/ question, but I sometimes wonder how fundamentally our perception of time has changed over the years. You don't, for instance, see any literature about anyone going back in time to change events said until the last 300 years or so. You indeed don't see any form of time travel at all, in any fiction across the world, save for folks falling asleep for centuries and waking up later. It almost suggests we had an entirely different view of time until recently, even at the layman level. Then again, in most civilizations, there's usually a thousand years or so before you see the mention of any color other than red in its literature, yet they are generally making multiple colors of dyes before then, so may be neither here nor there.

>>9756030
Time is something that our society created to keep track, and to determine the difference between past, present and future. We the people are the only mammals that suffer from >Time< because we created it and we are who we suffer from

Shitpost. Make some kind of statement.

>>9757454
Already too late for that, much of the universe is beyond the hubble and observable boundaries. Gravity propagates at the speed of light - none of that matter is coming back.

There's some thought that the "big rip" may result in a quantum vacuum event similar to the big bang, but there's no reason any such universe created would be identical to our own (QM dictates it pretty much can't be). Then again, there's more fringe theories suggesting this is happening all the time, only we don't perceive it, as the universes so created are effectively moving away from us at faster than the speed of light.

>>9757514
The vast, vast majority is beyond the boundaries. The actual universe is at minimum 200 times larger than what we can observe.

Based on what?

>>9757891
Fortieth post best post.

Can someone explain to me, how in theory there can be a room without time and how it could make logically sense? Thx

>>9757904
CMB

>>9758003
We don't even know if the universe doesn't repeat inside observable universe.
How can we know size of whole universe from CMB?

>>9757904
Is there any way of calculating how big the universe actually is based on the rate of expansion and time since the Big Bang ?

>>9758044
>>9758101
The observed density of mass in the universe is roughly is about 3 x 10^-30 g/cm^3, the observable universe is about 14 billion light years in any direction, do the math, and ya get 3 x 10^55g. All those red-light shadows at the edge of the observable universe from galaxies that have long left the hubble sphere continue this density.

Though the sphere appears almost 28 billion ly in diameter, it is far larger. We know that the universe is expanding. Thus, while we might see a spot that lies 14 billion light-years from Earth at the time of the Big Bang, the universe has continued to expand over its lifetime. If inflation occurred at a constant rate through the life of the universe, that same spot is 46 billion light-years away today, making the diameter of the observable universe a sphere around 92 billion light-years.

We get these numbers from the baryonic acoustic oscillations that fill the cosmic microwave background. In addition to standard candles, such as type 1A nova.

If the universe expanded at C during inflation, it should be 10^23, or 100 sextillion ly across, but of course the cascade scenarios indicate a burst.

So, instead of taking one measurement method, a team at the University of Oxford did a statistical analysis of all of the results. By using Bayesian model averaging they found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across. Which seems big, but is actually more tightly constrained than many other models.

Granted, the universe is flat, which gives it effectively infinite size, but as it has a finite age, all we can truly conclude is that the universe is much larger than the volume we can directly observe.
