genetic damage preventing cellular reproduction from environmental factors

>>8684592
1000 years ago the question was "why do 100% of us die in under 100 years? why aren't there occasionally people making it to 112 years or something else instead?"
1000 years from now the question will be "why do 99% of us die in under 200 years? why don't the ruling class of plutocrat immortals make their healthcare plans more affordable for the rest of us?"

You think I want people to know I'm 355 years old? Why would I want that?

(Continued)

Let me explain. If you went back in time, the atoms, molecules etc. that make you, don't suddenly cease to exist. Just like in the real life version of being able to travel slightly into the future, two you’s don’t exist, you don’t suddenly split in two, you can’t meet the future you because the future you and the you of now are the same. The universe doesn’t gain or lose atoms/information just because you’re travelling through time.

So the real reason why you can’t go back in time is this: The atoms etc. that are ‘you’ are scattered, and are not in the form of ‘you’ when you go back beyond the point of your birth. Also, your brain can only perceive going forward in time (this is apparent by every day experience and no known cases or perceivable cases to prove it otherwise.) Therefore, even if you WERE travelling backwards in time, you would perceive yourself as going forwards in time.

Another way of putting this, is that travelling to the past could never happen, because it would only be a ‘reversal’ of time, that which has already happened. For you to travel backwards in your forward state, there would have to now be a bending of time only for you, and you couldn’t exist in the same universe because ‘you’ already exist in there. There is no reason or mechanism to suppose that there can be two you’s existing in the same universe. Even if ‘you’ are just scattered atoms throughout the cosmos, your double existence would theoretically displace the entire universe.

And in the other half the ‘you’ who left the present, would leave a vacuum of ‘you’ for the entire present to future universe. ‘You’ would have to POP out of the present universe, and cease to exist, in order to exist in the past in your present form.

(Continued below)

And if you could bend time and exist in the past, as a double of yourself, how could you possible interact with the past universe? How could you touch it? As mentioned before, in order to travel to the past, in your present form, and not as a reversal of your present state (in a second time stream in other words) you would have to have time bent personally for you, if that was the case, you’d be moving in the opposite direction in time as the rest of the universe. Etc. etc.

You get the point. Real going backwards in time, is time reversal, and beyond your birth you’d be an unintelligent mass of scattered atoms. And any point where you were alive, you wouldn’t even be aware you were going backwards in time. Freaky, but I think, possible.

We could in fact be timeless right now, and only experiencing time because of the brain, who knows, I don’t.

(OP finished.)

We can't travel back in time because traveling back in time implies literally >traveling< to place XYZ. XYZ doesn't physically exist anywhere.

My best guess would be that it has to do with humans evolving as hunters who chased prey over long distances. Less body hair may have produced an advantage with respect to heat evacuation, meaning that humans could run for longer without overheating. But I dunno, that's just a guess.

But they doooooooooo. And I benefit from that, so fuck you.

They just don't give a heck, especially fucking India.

Ok true, but I'm sure they're just the Ramanujan shills and nothing more.
Most of them are at /g/ because of the IT thing while posting memes.

I can't think what they would do on /sci/ desu.

nice try troll, you almost got me to go outside and exercise

How to calculate your jump time:
Stand outside with a stick
When the stick stops casting a shadow, take the current time and add 12 hours. This is your Base Jump Time
Take the time of the sunset, this is your BJT base offset
Every evening, offset your BJT by the change in BJT base offset, if the sun sets 2 minutes later, move your BJT by two minutes
At your BJT, go outside and jump up and down for 1 MINUTE
Repeat until we reach the sun

The sun is 150 million meters away, each jump pushes the earth 9.8 meteres closer to it, it will only take about 16 million jumps to reach the sun. Please help

Neither of those hard. If you want a major that is actually intellectually challenging and stimulating, try Women's Studies. Women are the one thing men will never be able to understand.

>>8685541
What if I'm an Applied Math + Applied Applied Physics double major? Which area of studies do I apply my double applied majors?

>>8685541
why not both at once?

>>8685497
Like the monkey thing and typing out Shakespeare, all permutations can happen due to inherent physics. Thus, looping occurs, but only to a certain point. Past that, nothing that exists now may have never existed before and may never exist again.

If you want a scientific answer go google the "past-eternal Universe". Models of the Universe are still being debated today and you are going to have to get away from /sci/ and do your own research. The topic is pretty complicated and I sure me and the rest of /sci/ won't give you anything sufficient. If you want to argue about the eternal return /his/ might be a better place, just make a thread on Nietzsche or something.

geometrically

>>8685427
You mean categorically

>>8685422
>If multiplication is just addition
The multiplication of two positive numbers can result in a smaller number (e.g. 9 * 1/2), whereas the addition of two positive numbers will never result in a smaller number. So argueth Euler.

You could never hope to understand fundamentals with a brain like yours. You are still welcome to try reading a book on category theory.

The trick is understanding what each part of the fraction means.

The denominator is the size of piece you cut each whole number into.

The numerator is the number of pieces you have.

When combining fractions, or converting from mixed fractions to improper fractions, the pieces need to be the same size. Think of 1 1/10 as 1/1 + 1/10. In order to combine them, you need to chop up the 1 into 10 pieces. If you chop something into 10 pieces, you get 10 of them (hence multiplying by the denominator).

So 1 1/10 = 1/1 + 1/10 = 10/10 + 1/10 = 11/10

>>8684857
>How come multiplying the whole number of a mixed number by the denominator and then adding that to the numerator gives you the correct mixed number?

You have 1 which is 10 tenth. You add 1 tenth. that gives you 11 tenth, that is 11/10

>>8684891
Ah that makes much more sense.
Thanks.

this isn't funny. it was never funny. it never will be funny.

It's not a theorem of analysis, where the infinite sum is defined using a limit (of partial sums), which in turn is defined using a long expression involving the metric over the reals.
In Ramanujans theory of infinite sums (one of many), it's just some result and has applications in quantum electrodynamics and string theory.
No theory is morally better than others, but some are more commonly used than other, and the inconsistent ones are used particularly seldom.
