Hello there.The question is as stated:does light curve spacetime?We know that bodies with mass do curve spacetime but does a massless particle or wave like light curve spacetime?Thank you.
In principle. The energy densities needed to test it are impossible to achieve.universe function said:We know that bodies with mass do curve spacetime but does a massless particle or wave like light curve spacetime?
No.universe function said:Is there any physical body in the universe without energy?
How do you know it is correct?Every massless physical body has energy?If it did not have what would happen?Ibix said:In principle. The energy densities needed to test it are impossible to achieve.
No.
I think that we cannot observe things that do not have energy or experiment with them.But the question just came to my mind perhaps it is wrong.Ibix said:What do you think "without energy" would mean, physically?
If a massless body did not have energy then it would also not have momentum. I am not sure in what sense you could say that it even exists.universe function said:Every massless physical body has energy?If it did not have what would happen?
Ibix said:No.
I would say that these are properties of a physical system, just as energy is.anuttarasammyak said:entropy and distribution function in statistical mechanics,
You might argue that the wave function is the physical body, to the extent that makes sense in quantum physics. Energy is the corresponding eigenvalue, anyway.anuttarasammyak said:wave function or probability amplitude in QM
Light does not actually curve spacetime. Rather, it is the presence of massive objects that cause spacetime to curve, and light simply follows this curvature as it travels through space.
The most famous evidence for light curving spacetime is the observation of gravitational lensing, where the light from distant objects is bent by the gravitational pull of massive objects in its path.
Yes, light can travel through curved spacetime. In fact, it is the curvature of spacetime that causes light to follow a curved path, rather than traveling in a straight line.
No, the speed of light is a fundamental constant and does not change in curved spacetime. However, the path that light takes may appear curved to an outside observer due to the curvature of spacetime.
In curved spacetime, light follows the shortest possible path between two points, known as a geodesic. This path is determined by the curvature of spacetime, which is affected by the presence of massive objects and their gravitational pull.
