The dedicated Science/Space thread!

[anonymous-user]

Seeing as we don't have one...
First things first then, what do you know about Space?

I don't know THAT much but I'm really interested in general science and space as a topic so let this begin.

[GroundEffect]

I know calculating orbits sucks.

[Use Psychology]

Space. There's a lot of it.

[anonymous-user]

Moved already.
Damn.

[y2blade]

it has been moved

[Fearless Egbert]

Space is really, really big.

And mostly empty.

Boats, planes and trains in space?

Well, techically have planes I guess.

This was supposed to be in the lounge though.

Really good article in the Times yesterday re the universe, especially Kepler 22B.

Good idea you have there - send it over to the powers that be and see what they say.

I prefer discovery news for my geeky stuff in the morning.
Was reading this http://news.discovery.com/space/mars-life-habitabi...

Usually some good reads get thrown up on there daily.

Gravity is a pathetic force!

You need something as massive as the earth to give a force of approximately 10 newtons.

[Eric Mc]

There is more space on a space forum than a space thread.

If only we had one

[Big Al.]

It will happen just as soon as the revamped classifieds is out of the way.

[central]

[NismoGT]

Is this a place to post geeky facts/theory?

10 newtons on what?
It's not the same for everything.
the 10 (9.81) newtons is per Kilogram.

[HowMuchLonger]

Is there an equation for multibody gravity (more than two bodies)?

Yes, it's called the n-body problem, and it involves a lot of maths.

I assumed that would be obvious.

The way I heard it described is that a gravitational pull from something the size of the earth can be counteracted by the electromagnetic bonds of a bit of ground.

IE, imagine falling out a window. You're being accelerated due to the gravitational pull of the (huge) earth, yet the electromagnetic bonds between the concrete on the ground stops you almost instantly (and painfully).
