/sci/ - Science & Math

Just finished an astronomy class, learned about nebulas and shit, but I've got a question.

If you had a suit on for live preservation and another astronaut in a suit next to you, in a nebula, nix the radios, could you hear each other? Would the particles and atoms be close and dense enough for sound to carry?

heh, smart ass

Greetings /sci/,
I propose to you a project to solve one of the biggest unanswered questions of this century : What would happen if a sun made of lava and a sun made of ice collided?

The project, which hasn't been named yet, will consist of creating a computer simulation of such event. I will personnally contact all major universities and scientific organisations to get CPU time on a supercomputer. The computing time will be used to run a modified version of The Powder Toy. The simulation will consist of creating a sphere of radius 100 of LAVA and a sphere of radius 100 of ICE, separated by 100 units and then let gravity do the work.

I appreciate your feedback

feel free to explain why you think so(though you obviously aren't obligated too.

Now, I'm not a clever man, and I don't know anything about science, but I have a question.

In theory, if we had a super telescope and could move faster than the speed of light, could we send the telescope thousands of light years away from Earth and watch the history of the world unfold through it?

Similarly, if there were really advanced aliens thousands of light years away with a super telescope looking at Earth right now, would they be looking at the Earth's distant past?

I know light speed travel doesn't exist, nor do telescopes of that strength as far as I know, but hypothetically speaking.

We all accepted the fact that dark matter is increasing the universe radius, but eventually the universe will collapse in black holes anywya, that will pull toward each other. There has to be a bigger one, and it will eventually, in the course of billion years, pull everything inside it, thus effectively "eating" the whole universe. Isn't this the Big Crunch? There has to be a big bang after such a thing, and isn't this a proof of the Big Crunch?

TL;DR: If everything is black holes, in a fuck ass long time everything will be pulled together again, thus another big bang

Also, what the fuck happens when 2 black holes meet?

Sorry in advance for any error in my english.

I plan on studying economics so that when I am rich, I can fund space exploration missons and development of space technology.

But the problem is: Do I really become better at making money if i study economics?

Also: how do I make money? I really want space exploration to grow.

Reality is boring OP, especially when dealing with the dreadful astronomical facts about distance and lighting.

That's why almost every photo of space stuff is false coloured and pictures are exaggerated or take so many liberties. Space is a lot less beautiful than one would imagine it has right to be.

If I have two action groupoids A//G and A'//G', is a full functor between them an equivariant map?

What is the effect of Dubstep on the humain brain?

Is there any theory proving this?

Who else agrees that, in the God debate, it's not that one cannot really know whether or not God exists, it simply is about him being a human creation. We create almost everything there ever was, identity wise. A mythical creation such as God is simply impossible to actually exist, therefore impossible to ever see. No one has been him, no one has communicated with him, he is nothing. He is a story thought up by the time's greatest minds, minds that used it for some tyrannic benefit.

Humans are arrogant. The universe was not created by their image.

bumping with science

Oh here it is, that there was the Eagle Nebula

>>2484329

i was under the impression that the hydrogen in the nebula was emmiting light as a result of electron cascades due to incident radiation from nearby stars. this does not occur in all nebula, but hte ones in which it does are known as emmision nebula.

Pic related, the pillars of creation are an emmision nebula

I'm doing some self studying over the break between my courses this Christmas. My interest is astrophysics, so I'm wondering, what math am I going to be needing? Calculus I, II, and III?

Any recommended textbooks? The only one I know of is Introduction to Modern Astrophysics by Carroll and Ostlie.

tl;dr title of book for astrophysics please and what math

What is a good documentary on Astronomy? I'm looking for something to further a new found interest of mine.

The most beautiful image ever.

Hey everyone.
I would actually call myself an atheist because I most certanly mean that the bible and the coran and all of those books are bullshit. It's also prooved.
But I've been thinking about it for a long time, browsing google, reading a whole lot about it.
And what I've come up with is that even though the bible etc is bullshit, there has to be a God.
I wont believe that all of this is some random creation from a huge explosion, because then it would not be such a perfect "invention".
And if there was something special exept from a certain amount of LSD in Jesus' wains, there would NOT be any way that mankind, especially back in those times, to write down, and explain that one high human being can conquer all of naturs laws.
The universe can't last forever, and it can't just end into nothingness eighter.
When we die we can't magicly from a rotting body, transfer our soul into an unborn fetus in someone's tummy.

I know you also have thought of this, and I'd like to know what you think of this.

tl;dr All religions are lies BUT there is a God.

Wutup /sci/,

so let's say i want to buy a telescope...around $2,000.
so what would I be able to see with it? i know that alot of the cool images are pretty much photoshopped or taken with a hubble telescope...so what will I be able to see...post pics and links...thanks.

Pic shows what I won't see through my telescope.

I dont know quite how retarded you are but does this picture look like part of a brain to you?
Or does it look like clouds of gas in which stars are born?

>>1106945
I have much more.
I'll post some, If there's any demand.
