He's probably talking about the absolute reference frame created by the cosmic microspace back wave radiation because he's retarded.

wat

Shouldn't it be 1/4?

Hey /sci/, i need help with my high school homework. Our teacher asked us to prove that P != NP.

How can i prove that?

okay, hear me out. my physics teacher back in high school couldn't answer this back in the day.

from personal observation, it seems that the colors of daybreak last much shorter than those of sundown. what I mean is that when the sun goes down, there seem to be many more colors, and for a longer period of time. When it comes up, it has less colors, it seems to go straight from blackish to blue.

I thought about it, and is this because the rotation of the earth is fucking with our perception of the sun's visible light? when the sun goes up, is the light going with the direction of the earth's rotation, thus making the light look like higher energy wavelengths of blue and violet? which would explain the lack of "different" colors, the blues and violets would blend in more easily.

and when the sun goes down, is it working against the rotation, making it look like lower energy than it is, producing the brilliant reds, oranges and yellows of the sunset because the rotation is warping the light?

If not the earth's rotation, is SOMETHING making that happen?

>Xenobiology

"Aliens, if they exist, must have the same bodily chemistry as us, live off of water, live on a similar planet orbiting a similiar sun, and the planet must be located in a tiny range of distances from the sun called the habitable zone (which Earth happens to be in the center of lololol)"

The only interesting thing to come out of xenobiology is the Drake equation, which is something that anyone could come up with after 5 minutes of thought and its worthless scientifically because we won't ever know the parameters to any kind of precision.

What are you trying to to? Is it something to do with the ponies I keep hearing about?

I don't like where this is going.

>and there's nothing after it
Not necessarily. You know we might very well live in an universe where time has no ending. We can't tell but we do know that it's tending towards entropy. A timeless universe like that would be in a high-entropy state most of it's time but sometimes there would be low-entropy pockets of varying sizes. One pocket might give birth to a molecule. Another time a few molecules might even assemble to form a microscopic piece of dirt. And another time a whole galaxy exactly like ours might just pop into existence and with it the rest of our known universe. An event like this would be extremely unlikely and rare but time is meaningless when there's no observer.
The scary part is that it's much more likely that our universe just assembled out of nothing instead of being created over time with a big-bang at it's beginning. It would happen endless times in an endless universe.

Thanks to the above for informing me of where my post was reproduced. Having visited their /new/... wow! That place is a racist shithole, moreso than 4chan can be. Which leads me to a point...

How on Earth has it come to the point that huge portions of the population can come to believe outright lies about policy, science, religion, etc?

HOW, AMERICA?

What's your favorite thing about the Universe?

Mine is the sheer power of the stars.

Blows me away.

What happens if a dark-matter galaxy collides with a matter galaxy?

For me, it is far better to grasp the Universe as it really is than to waka waka waka

>scientific reason

Uh, yeah, genetics.

I really love to teach people about things. Scientific literacy is something I want to spread to as many people as humanly possible, especially to children.

So, I ask you: Are there any kind of volunteer opportunities available for me to teach kids about the universe, either in schools, public libraries, museums, anything like that? I tried looking up volunteer opportunities for my local schools, but all I could turn up is helping out with canned food drives and shit. I just want to be able to go to a room full of kids and tell them about all of the stuff they probably are never going to learn in public school, and to answer their questions about the universe.

How could I, as an amateur astronomer, go about doing something like this?

Pic related. I started wanting to do this when I saw that segment in Cosmos where Carl's in an elementary classroom passing out pictures of celestial objects, teaching kids, inspiring future generations to look towards the sky. I was amazed and inspired to see that children could become so excited and genuinely interested in learning about the universe, and I would like nothing more than to do this myself.
