im basing my assumption that it is no, because light is energy acting as aparticle and because it creates no mass it has no gaviational attraction on other particles, i need to find proof if my assumption is correct?

turin said:Allusion to light is unnecessary. If you are already willing to accept that something that "creates no mass has no gravitational attraction on other particles," then that seems to answer the original question (albeit incorrectly), as far as assumptions go. However, there are a lot of people around here who would like to say that light (a.k.a. a photon) does have (relativistic) mass, and they are not strictly incorrect. Bottom line:
Energy gravitates.
so light *********s and gathers inside itself
I have only considered the ideal infinitesimally thin ray of light, but that doesn't help answer the above question. If you consider two such rays of light, then I'm pretty sure that they would tend towards each other, but I'm not positive, and that may not be a satisfactory consideration to you. As far as a finite volume of light traveling through space or something, I don't know. The theory says that the electromagnetic field causes spacetime curvature, but the one time I tried to calculate the curvature caused by electromagnetism, I had to abandon the effort because it took too much of my time. Maybe someone has done some kind of numerical calculation and published it.taylordnz said:so light floculates and gathers inside itself due to the gravity it creates?

Stingray said:light is classically a wave.
taylordnz said:ill revise my question again, if you had enough light condensed into each other would it create a small but minute gravity field?
Dors_Venabili said:It's actually the other way around. Photons DO NOT create gravitational fields. Rather, massive objects in angular velocity fields will gradually lose their mass to photonic energy radiation so long as they remain in the field. However, to be able to experimentally detect these effects requires either incredibly massive objects or extremely high rotational frequencies - or preferably - both.
There is currently no scientific evidence to support the idea that energy directly creates gravity. However, according to Einstein's theory of general relativity, mass and energy are closely related and can influence the curvature of spacetime, which is what we experience as gravity.
No, gravity is not considered a form of energy. It is a fundamental force of nature that describes the attraction between objects with mass. Energy, on the other hand, is the ability to do work or cause change.
While gravity is a powerful force, it cannot be harnessed as a source of energy in the traditional sense. However, some scientists are exploring the possibility of using gravitational potential energy, such as the energy stored in a raised object, to generate electricity.
According to Einstein's theory of general relativity, mass and energy both contribute to the curvature of spacetime, which is what we experience as gravity. The more mass or energy an object has, the stronger its gravitational pull will be.
Currently, there is no known way to directly manipulate or control gravity using energy. However, some scientists are researching ways to potentially manipulate the curvature of spacetime, which could indirectly affect gravity. This is still a topic of ongoing research and is not yet a proven concept.
