sup /sci/

i was linked a really cool thing a couple days ago
it was i think a hubble photo that you can actually zoom in a shit ton and see incredible detail in one tiny square u zoom into

can anyone help?

>I don't think Sagan ever prescribed such a thing. What you're describing is a Malthusian view, Sagan was a Cornucopian.

Alright, I found the quote to prove you wrong.

Carl Sagan's <span class="math">Cosmos[/spoiler], chapter 12 (page 257).

"No civilization can possibly survive to an interstellar spacefaring phase unless it limits its numbers. Any society with a marked population explosion will be forced to devote all its energies and technological skills to feeding and caring for the population on its home planet. This is a very powerful conclusion and is in no way based on the idiosyncrasies of a particular civilization. On any planet, no matter what its biology or social system, an exponential increase in population will swallow every resource. Conversely, any civilization that engages in serious interstellar exploration and colonization must have exercised zero population growth or something very close to it for many generations. But a civilization with a low population growth rate will take a long time to colonize many worlds, even if the strictures on rapid population growth are eased after reaching some lush Eden."

My name is Yahweh.
I am the unelected perpetual dictator of the entire cosmos.

Ask me anything.

Hello /sci/,

What is the vacume of space made of?

In the universe (not in math land) since there is a smallest possible distance and unit of time, does that mean there is a smallest unit of velocity? Like a Planck Velocity? And does that mean the velocity everything on the macro level is finite?

Your mother's so dumb, she watched nothing but The Oreilly Factor for five months straight, thinking she could find a Higgs boson in his "no spin zone".

Then she became even dumber, because she was watching The Oreilly Factor all the time. It was a vicious cycle that could only end in tragedy.

Your mother is so dense, a black hole's Roche limit with respect to her would be smaller than its own Schwartzschild radius.

Your mother is so fat, she can see the redshift of her own toes. (Or would be able to, if they didn't reside outside of the light-cone of her eyes.)

Your mother is so flatulent, the accretion disc of her intestinal gases forms the powerful X-ray source at the heart of our galaxy. (It is also home to many brown dwarfs, as her rectum is the location of a gigantic stellar nursery. When she's constipated, she shits compact stars.)

Does anyone have the picture of a robot with a solar system map in his hand?

Let's discuss our favorite things about the heavens.
Galaxies, Quasars, Black holes, Nebulae, Anything of the sort, Post pictures as well, they're beautiful.

What literature conveys immense proportions best? Poems, words, phrases, I'm looking for anything. The human mind is very poor at imagining distances between stars. I need to create a short sentance that really puts the point out there. Any suggestions help.

Since every point of the sky contains stars, why is the sky not white?

Sup /sci/, I have to pick my major soon and I want to pick something scientific, however, I'm terrible at math (I failed Algebra 2 in high school and had to take it as a senior...although I get it now that's pretty pathetic). I would really like to try and get better at math but I was wondering if you guys could tell me some options for scientific majors which math doesn't play a HUGE role.
Or should I just suck it up and take a ton of math classes until I get it?

Pic unrelated.

Battery powered cars are neat but you're essentially replacing fossil fuels in petroleum with fossil fuels in coal which is the #1 way we receive electrical power here in the US. If I want to purchase a rechargeable battery powered car in the future what is a viable way to power it without using fossil fuels?

Picture related, it's the Sombrero Galaxy.

So, I went to a nearby community college and got my associates degree, a few years ago the state funded it to be a state university so I reapplied to school. Easily got in of course but asking around they don't have a regular geology department and they can't offer a geology degree. Instead they have 'earth sciences' which is meteorology, hydrology (people study that?), and geology sort of mashed together.

I don't think it's worth it to get an 'earth sciences' degree but maybe I'm wrong. Maybe I can use it to go on to graduate school and get a real geology degree? My grades aren't so great from when I got my old degree like 7 years ago so I don't know what to do at this point.

Using science only.
Prove to me that the world wasn't created last night while we all slept.
That we are not brains in jars being fed information for scientific experimentation.
That scientific principles we observe now are the same as they were 2,000,000 years ago.
That scientific principles we observe here are the same as they are in the Sombrero Galaxy.

We all have faith people, some people simply accept that we do.

Is this picture artificially colored?

Sombrero Galaxy.

Do you believe in aliens /sci/?

Let me get this.

If we were to try and go to another Galaxy at the speed of light, it would take hundreds of millions of years.

Would we experience any of that time at all? Wouldn't it be instant due to special relativity and time dilation?

If we kept getting closer to the speed of light, we would feel like we were moving further further beyond it, right? Even though from an outside viewpoint, we would appear as though we were moving at 99.999% then 99.99999%.

I'm asking this because, if we moved the earth near the speed of light, it wouldn't matter if a million years went by because we wouldn't experience a million years right? It would be less due to space time warping or something like that?

Come to /sci/
there are 4 threads on the first page about God.

That's it /sci/ you had your chance but some months in I see that this is all you're capable of. Goodbye.

And nothing of value was lost ... yeah, well, enjoy your /sci/ - Philosophy & Religion board. Everyone who may have contributed something better will leave or has already.
