General Science Discussion Thread!

How...how do they no that without getting close to it?

Science.

Because of behavior of objects near a black hole, and all that radiation that black holes spew are the best indicators.

 

[Dr. Javelin]

tbh we really don't know that much about black holes

i doubt they'll discover what's inside one in my lifetime

Can't we just send some monkeys inside of one?

 

[Dr. Javelin]

sure, but how are we supposed to know what happens to the monkeys after crossing the event horizon?

 

[DragonFreak]

You attach video cameras to them.

 

[Ray Trace]

The nearest black hole is about 1600 light years away. Good luck reaching that.

 

[EctoBiologist]

let's not forget that the stars we see in here might as well be dead right now.

 

[Lakituthequick]

You attach video cameras to them.

If light and radio signals can't escape a black hole... you know the rest of the question.

 

[Iggy Koopa Jr]

We then send more monkeys.

 

[Dr. Javelin]

You attach video cameras to them.

and you plan on getting the video cameras back...how?

remember, they can't transmit any data back because all the electromagnetic waves they emit would be pulled into the black hole

 

[DragonFreak]

I was joking. I knew I should've put a [/joking] tag there.

Dang is there anyway to keep the camers from loosing signal at all?

 

[Lakituthequick]

Dang is there anyway to keep the camers from loosing signal at all?

There is a short answer and a slightly longer answer.

Short answer: no.

Longer answer: since black holes' gravity fields are strong enough to prevent radiowaves from escaping, no.

 

[ernesth100]

Is a black hole different from a wormhole?

 

[Lakituthequick]

Yes.

 

[LeftyGreenMario]

A wormhole, or the Einstein–Rosen bridge, is basically a tunnel that connects two different part of the universe while a blackhole is simply a gravity well created from inconceivable masses. Think the universe as a long sheet, like the space-time fabric. The wormhole is basically a tube that connects different parts.

It's conceptual right now, but at least it has some scientific validity.

 

[Rise Up Above It]

Well ants are smaller...then there are microbes...then atoms...then...nothing. So we're actually kinda big.

no you're still extremely insignificant

Well, nice to see you have such an upbeat attitude.

But really, yes. http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html

 

[Iggy Koopa Jr]

I like the subject of the subconscious.

 

[banjonator1]

atoms...then...nothing

quarks and bosons would like to have a word with you

(and prolly some other sub-sub-atomic particles I can't remember)

And what's nothing? A perfect vacuum can't really exist, you know that? In space, it's just matter being more thinly spread.

 

[banjonator1]

ELECTRONS

electrons are one of the three elementary components of atoms

i'm quite sure ernest knew what an electron was; we're talking about the components of subatomic particles here

 

[LeftyGreenMario]

What about neutrinos?

Millions of them phase through neutrino detection machines unnoticed, so only 10ish are studied.

"About 6.5×1010 solar neutrinos per second pass through every square centimeter perpendicular to the direction of the Sun in the region of the Earth."

Dang.
