 P: 69 Suppose, I become twice as big as the earth. Then Can I have my own Gravity!
 P: 51 yes. u do even now.
 P: 251 That's pretty damn big. You're going to have to eat a lot of ice cream. (That's what Vin Diesel *forgive the spelling of his name* did to gain poundage fora movie).
 P: 5,641 Human Gravity! As Gurkha pointed out, you already have your own gravity. You exert just as much pull on the earth as it exerts on you. If you went into space, you might carefully put some little speck of something into orbit around you and could thereby have your own moon.
 P: 1,409 Gravity is only a theory. Using the logic of Intelligent Design, how do you know it even exists?

Not by yourself. It takes two to gravitate towards each other.

How strong is your force of gravity? About this strong:

$$F=\frac{Gm_1m_2}{r^2}$$
where F is the force of gravity, G is the universal gravitational constant, one of the m's is your mass, the other m is some other mass, and the r is the distance between the two of you.

Notice that being smaller in mass than the Earth might make your own force of gravity smaller, but it's always greater than zero. Notice, also, that being further away might make the force of gravity smaller, but the force of gravity will always be greater than zero.

Every star you see in the sky is pulling on you at least a little bit. You're affected by everything in the universe - even the things so far away you can't see them.

Likewise, you are pulling on every star and every planet that exists in the universe. Your presence in the universe affects every other single thing in the universe.

Or, as Emerson, Lake, and Palmer said, "It is perfectly clear.... you were meant to be here ......... from the beginning." (I like that song )

Tee hee. (At least, I presume you jest.)

Edit: just stumbled across this, probably the seed for Skyhunter's comment.

Whether or not there is any other object, he still has a gravitational force. If he has mass, he has gravity.

Challenge: What size object, at what distance, orbiting at what speed could be a moon for a 50kg person (assuming a spherical person)?

Gravity is not non-local; it moves at the speed of light, so if something's light hasn't reached you yet, neither have the effects of its gravity.

No it wasn't but it is hilarious.

Now I understand what's the whole worldwide famine about!

That's priceless.

Only if you are good...
 P: 69 That means all I have to do is get that big
