Why is the universe so young?

[Anonymous No.10115885]

because this early era is the one with the highest probability for life to evolve in any of the galaxies present

[Anonymous No.10115957]

relative to what?

[Anonymous No.10115960]

>>10115957
Time, obviously

>Why is the universe so young?
Where did this anomalous and arbitrary seeming increment of time, 14 billion years, come from?
good question

Infinite number of years possible. We are born in the first 16 billion. Literally zero percent chance of this happening.

[Anonymous No.10117963]

>>10117890
you're probably wrong, the first 200-300 million years it was too hot for stars.
And persuming heat death we will have 10^106 years before there's only photons and leptons left
Therefore it's a closed interval [2E6, 10E106]

As for OP's question, if we're not completely hegocentrical, we can assume that humans aren't special and that alien life does exist.
Maybe this is the golden age of life?
Or maybe humans actually are a statistical fluke, and that it's only luck of the draw.

Not sure how this train of thought works. Several problems with it actually.
Is it really logical to talk about the probability of things that have already happened? Doesn’t seem so, but how come it is logical to talk about the probability of things that will happen in the future?
Is it really an infinite number of years possible? Isn’t it possible that the birth of life is improbable before of after a certain point in the lifetime of the universe?
Does probability even exist in a universe in which every single event is governed by the laws of nature on any scale we can scientifically make sense of, i.e. disregarding quantum physics?

[Anonymous No.10117974]

First life to evolve and create super-intelligence takes over the universe. After that, nothing can evolve. Therefore, if you find yourself as evolving life, you will find yourself at around the time when life first starts to evolve.

thx for thoughtful responses. is the heat death really supposed to be not for another 10^O(10^2) years?

[Anonymous No.10118124]

>>10117890
Then literally any other year also has 0 percent probability

[Anonymous No.10118131]

>>10118124
if years are distributed evenly then us happening in the first 10^10 of them seems really unlikely

There is no uniform distribution from 0 to infinity

[Anonymous No.10118321]

>>10118131
>>10118316
And if there were, then the likelyhood of us happening in the first x years, where x is any natural number, is also probability 0

[Anonymous No.10118325]

For complex life to evolve there needs to be enough heavy elements around while also enough light elements to create relatively large stars such as our sun because red dwarfs are a meme.
That time is around now.

The President of GT got a raise from $700k/yr to like $1.1M/yr immediately after I got expelled.

[Anonymous No.10118369]

>>10118316
im not thinking that there is a time infinity, but as another anon suggested the heat death may happen at time 10^106 years, and if the years between thay are distributed evenly then it's practically probablity zero a.e.

Nonsequitor. Unless you're trying to say he got a raise for getting rid of you, but you're not that significant.

[Anonymous No.10118392]

when was the last time the universe changed radically and are there any predictions about when this "era" will end?

[El Arcón No.10118400]

>>10118385
Non-sequitur means "does not follow." I think you were probably going for "post hoc ergo propter hoc," but yes, I am suggesting that he go this eccentric 50% raise in a time of sharply tightening state budgets because he made some unethical choices.

[Anonymous No.10118406]

>>10118400
why were you expelled?

[Anonymous No.10118413]

>>10118400
His raise does not logically follow from your expulsion. There may have been unethical decisions which brought in extra revenue that he pocketed, but expelling you did not bring it in, hence non-sequitor. What did you get expelled for?

Nor did I claim it did. I claimed it happened shortly after my expulsion.

>Is it really logical to talk about the probability of things that have already happened?
How on earth would it not be? You can examine the logical probability of a happening by constructing the past case before it happened and evaluating the probability. You find a coin on the ground faced heads up. Assuming it wasn't consciously placed, what is the probability of it landing that way?

[Anonymous No.10118850]

Stand the question, its cause and effect, on its head. The reason why you asking the question is because the universe is young (a variant on the anthropic principle, you're goldilocks, etc).

In a sufficiently old universe, there's no life both due to entropy and also (same thing) conscious/animal beings coming to realize that there's no point so either they do the usual petering out competing over resources, or they do the higher thing of self-delivering upon realizing the pointlessness of it all.

[Anonymous No.10118963]

>>10118850
The point is that if life doesn't prevail the universe dies, if life succeeds -some form of it- will devour any resource available to make new shit, unless for some reason this applies to everything but the universe itself. Maybe if you then go bigger and further in time you'll find another situation like ours. I mean if life doesn't give up; the only thing it can do is consume and grow, eventually reproduce. Alternative is death, at least in this reality you have one fundamental choice, live or die.

Well you have to be careful. If you want a chain of events to happen just right, you can make the probability of an event happening arbitrarily small when it doesn't need to be that restrictive. Also, you have to be careful of the question asked. For a simple example, if you are going to flip a fair coin and ask the probability of getting a heads, that's 1/2. After you flip and it comes up heads, you ask what's the probability I got heads, that's 1 because it's measured to be so. If you ask what's the probability that I could have gotten heads, that's 1/2.

You always have to be careful asking things expos facto because you can skew the probability to be small and think there was some extreme luck on your side when there either was a cause you don't know of or you've put yourself in a box.
