"Why" is a pretty hard question OP. Far as I've seen in my education, we don't have a good explanation why our current model seems to be the way things are. Maybe things aren't actually this way and we're dumb. But we only know more or less how things work, not why they do.
>>7795614 >Why does the speed of light have a speed limit?
tl;dr: if our universe is causal and local, we should expect a maximum speed at which events can cause other events.
Let's play God and imagine we're designing a new universe. The universe is some space, occupied by things, and stuff happens in it, to be very, very vague. What fundamental guiding principles should we use to build our new universe?

hi, i wanted to ask /sci/ a question about linear algebra.
i'm new to this board, and i cheecekd out the /sci/ guide page (which was really good btw), but i couldn't find anything on linear algebra. my professor said that the book we will be using for linear is not very good, so i was hoping some of you anons could give me some linear algebra textbook suggestions.
My wife is under the impression that she needs to squeeze out any kids she wants by or before age 30 ish as, she believes, the likelihood of birthing an autist increases by some percent every year she waits longer.
Have you ever heard or seen anything of this nature? I can imagine why this might be the case but she has shown little evidence to support the claim.
>>7795511 I know, and I appreciate the input, I know you guys aren't my personal research team, just curious if anyone else actually took those statistics seriously or if it was a bending of the truth.
Is there a particular reason for this though? Should we all be reproducing at a younger age? It makes me wonder because women and men can donate eggs and sperm for later use, do those facilities take age into account?
Again sorry, don't know who else to discuss this with.
>be NASA >only been to the Moon once... 40 years ago >most people still think moon landings were fake to this day >be Elon >wants to go to Mars and terraform it >suddenly there are actually millions of people right now who believe Elon can pull it off
>>7795467 >Has lots of money >Has hired probably the best talent in the field, next only to NASA and even that is debatable >Is actually doing shit with the money and engineers he has, and well documenting all of it to increase support for his company both from the public and investors.
I think that he won't be able to do it in his life time but one day we will get there, it is obvious.
Btw, there is no majority who think the moon landing was faked. The only people are the 3 guys who browse /x/ and their friends.
>>7795470 Statistically (based off the average 2015 US life expectancy) he has until about 2052 to get to Mars. With life-extending treatments that he'd easily be able to afford / get in line early for, I think he's definitely going to get his wish of dying on Mars. Terraforming obviously won't be achieved this century.
How the hell do you guys keep up with all that terminology in probability theory? Namely, how do you tell apart and remember those: Probability distribution, probability mass, probability density, probability distribution function, probability function, cumulative density, cumulative distribution function
>>7795379 It might help if you disregard the word Probability in all those. If a probability theory question pops up, you just imply it includes that and not just ordinary "mass, density, distribution" etc
>>7795249 Considering that any knowledge that I could impart requires 3500 years of preparation, so simce I have a basic understanding of metal working I'd forge some iron and conquer the world, then I'd just try and bang as many Neolithic bitches as possible.
