If I understand everything correctly, gravity affects particles with mass/energy. How can it possibly affect spacetime? Doesn't it have to "grab" something?

That right?
What about neutrinoes? Or other non realistic particles that matter!Originally posted by Tail

When doesn't it? Can you mention at least one case?Originally posted by pmb
Gravity *can* curve spacetime. I doesn't mean that in all cases that it does.
Spacetime includes space.And it can curve space as well as spacetime.
That I cannot agree with, even though I don't know much about this.matter defines spacetime (loosely speaking)

There's a story about gravity and relativity that is not told as often as it should. It goes back to Newton and is quite revealing of how physicists think.Originally posted by Tail

I can give you three examplesWhen doesn't it? Can you mention at least one case?Spacetime includes space.[/B]
Obviously. However I think you missed my point. It's possible for space to be flat and spacetime be curved. In fact that's exactly the case for a flat universe - I.e. in a flat universe space is flat = however spacetime is curved.
Spacetime includes space.
Hello DOC, I am thinking virtual particles.Yes neutrinoes have a little mass as they say.Condensed high frequency powerfull points of energy are always full of something.Originally posted by Doctor Luz
They have mass/energy.
What
non realistic particles are you talking about?

Sorry,New here! Should the anti-matter be attracted to ant-gravity?Originally posted by LURCH
I believe the situation you are describing reffers to negative energy, not antimatter. Nagative energy (and whatever negative matter might be created from it) is gravitationally repulsive. Though I've not seen experimental data, it has been side several times here in the Forums that antimatter is attracted by gravity.

Gravity is a force of attraction between objects with mass. It is the result of the curvature of spacetime caused by the presence of mass or energy. This curvature causes objects to move towards each other, creating the force we know as gravity.
Mass and energy are the sources of gravity and they affect spacetime by curving it. The more mass or energy an object has, the more it curves the fabric of spacetime, resulting in a stronger gravitational pull.
The relationship between mass/energy and gravity is described by Einstein's theory of general relativity. It states that mass and energy are equivalent and can be converted into each other, and both affect the curvature of spacetime, resulting in the force of gravity.
Gravity affects the motion of objects by causing them to move towards each other. This can result in objects orbiting around each other, falling towards each other, or even accelerating towards each other depending on their mass and distance.
Currently, we do not have the technology or understanding to manipulate or control gravity. However, various theories and experiments are being explored, such as the possibility of creating artificial gravitational fields through advanced technology or harnessing the power of gravitational waves.
