Hi the brilliant SpazzyMcgee i wnt ask to you u said that energy also generate gravity , then what is gravity?

Question

i think that mass curved space thats why gravity, energy effects mass (photoelectric effect ) , mass effects enery thts why the light bends near a massive body . the reason is that both effects space and things always trying to go in straight line but due to curved space it seem,s us like that bending circulating etc. and give the answer is space ia form of energy or what is space its what my previous question

Answer 1

Gravity is a force associated with matter.

  Light does bends around a massive body but it depends on mass and size.

  A 2 solar mass star  1 million km in diameter would have a rather benign surface curvature.

  A 2 solar mass sphere 3km in diameter would have a curvature so extreme that light could not escape the surface it would be invisible.

  If a black hole could exist this is what it would be.

Answer 2

Gravity is actually a curvature in space-time, not just space.  Distance is the measure of space, so a curved line in space changes distance in at least one direction, i.e. it changes direction.  Speed is the measure of space-time, so a curve in space-time is represented by a change in speed in one direction, i.e. it accelerates.  Mass produces a curvature in space-time locally, so anything entering a gravitational field will accelerate, just like drawing a line on a curved surface will follow that curve.

Answer 3

Matter warps spacetime in its vicinity, which is what we experience as gravity.  Technically, all matter IS energy, so you could say that energy also has gravity.  However, matter is composed of fermions, which have mass and therefore gravity.  The particles associated with the energy you're talking about (light) are bosons and exhibit different characteristics than fermions.  For instance, bosons don't take up space and have zero mass, and hence, zero gravity.

Space is not a form of energy.  There is a latent form of electromagnetic energy, called the Cosmic Microwave Background, which permeates all of space, but that energy is not intrinsic to space itself.  The best explanation we know of to describe space is that it's sort of like the framework upon which the universe is built.  If all the matter and energy in the universe were lines on a chart, then space would be the grid.  It's just weird because some of those lines would bend the grid!

Answer 4

E=MC2 that shows that energy can be converted into mass or the reverse. Gravity is just the attraction of 1 mass to another...

Answer 5

Shery, the spin of the earth would fling us out, not pull us in.

And sorry, I don't have an answer for the main question.

Answer 6

i saw some very simple experiments on the history channel,

they had proved electricity produces magnetism and magnetism produces electricity.  they showed the experiment with diamagnetism (due to temp i think) where a frog usually not highly magnetic could be suspended in air.  they have also used 2 chemicals and produced a plastic magnet.

i think our (the earth's) magnetic field shields us from too much solar radiation. is it possible the center of the earth is plasma and that with the spin produces gravity?  and if plasma is considered energy then gravity could be produced by energy.

Answer 7

space is not a form of energy! god, either youve asked this question 3 times today or for some reason people have this retarded notion that space is energy. go away!

Answer 8

Gravity is a force associated with matter.

Light does bends around a massive body but it depends on mass and size.

A 2 solar mass star 1 million km in diameter would have a rather benign surface curvature.

A 2 solar mass sphere 3km in diameter would have a curvature so extreme that light could not escape the surface it would be invisible.

If a black hole could exist this is what it would be.
