An interesting little science fact

Actually, the REAL effect here is density. The earths core is far more dense, and thus gravitates more strongly, than the surounding rock. Thus, closer to the core, you get the greater density gravatational field, due to closeness, however, at some point, the gravity lost due to having less total mass counteracts that.

This is not to say that any other posts were wrong, just that they aren't relevant in this instance.

Oh, come on... some of the other posts are wrong!

Yeah, well....

Why did you edit to a blank post?

haha

I wrote something, went to edit it to add something, then hit the delete button while it was highlighted

Anyway, the OP's fact IS interesting because it points out that the earth is not a perfect sphere with constant density.

Stop editing after I quote you!

Ctrl-Z next time.

Hahaha, I was make grammar mistakes or want to add something after a post. Instead of posting 10 more times, I just keep editing it.

Going back to reality guys, would it be obvious that a person will be killed instantly when he/she is going to be enveloped by a molten iron core ...unless they are superHEROES

You are affected by it on the moon. Just not a whole lot.

wow...he got that right. Cheers man :beer:. So the moon is still falling towards the earth in some way ??

Yeah; everything that orbits another body is actually falling towards it. It just has enough velocity that it keeps missing the planet as it falls towards it... given enough time, all satellites will spiral into whatever they orbit (EDIT: That assumes totally solid bodies and no outside influences).

Do we really need to explain orbital mechanics in this thread?

What does that have to do with this thread?

Yeah it makes sense now (remembers about satellites =D)

The Earth's mass still warps the spacetime around it, and their combined gravitational force keeps the moon at a relatively fixed distance. (The moon is very, very slowly receding away from the Earth) We feel the moon's gravitational force here on Earth as well. Tides? The moon pulling water towards it.

Yeah, but were talking about orbital mechanics, not the effects of special relativity on astronomical bodies.

Man...you guys are smart. We need ppl like you educatin' . Totally dig Discovery Science channel...I wish I can have it back (dang you bills ! "shakes fists")

This was probably already answered, but the reason for that is that the core of the earth has higher density than the outer regions. At least I think that's the reason.

Do you not understand the concept of not wanting to read 60+ posts?

 

[Powermoloch]

you got that right Argo

Really? We're not talking about gravity on the Earth? (Special Relativity is ALL gravity) Boy, you really fooled me, with the topic summary saying "Gravity related" and all, and with the discussion about the reduced pull of gravity at farther distances. When did the discussion turn to orbital mechanics? What's that? You left your brain in the fridge and haven't been using it for awhile? Good, because you need to chill.

At least Argo has his heart in the right place. Turn the caps off and calm down. Are you a pre-teen by the way? I hear they have nasty tempers. (just like yours)

Edit: Tick got ticked off. Funny.
