: Virtual gravitons like virtual photons are not constrained by the speed of light.

Hello everyone.

Isn't gravity geometry of space? If so why talk about some virtual particles? Is it for mathematical analisys?

Gravity is a field that is in many ways diferent from electric or magnetic field, but it's still a field.

So what is a field anyway. I thought about that and I agreed with the fact that a field is a PROPERTY OF SPACE. Since space is continuos, that property acts "momentarily".

Electric an magnetic fileds differs from gravitational field in a way that gravitational field actualy curves space and time, while el. and mag. changes it's other properties.

So why don't the electromagnetic waves travel at infinite speed, you may ask. That is, of course, because EM waves are in fact pulsating el. field and. mag field. That's why the speed of EM waves is limited. But you can look at this in a way that lightspeed IS an infinite speed since it's a fastest way to transfer information. You can't send information with fields, it has to be a wave. Wave is actualy A CHANGE OF FIELD which cannot travel faster than light.

So what is the reason for discusion about some fictional vitual particles?
