is gravity considered a light wave?

Question

if the sun were to vanish, would the gravitational force continue for the same period as the light, about eight minutes?

Answer 1

Gravity is not a light wave, but some scientists believe that gravitons (which "trasmit" gravity) travel at the speed of the light, so according to this theory, the answer to your second question is "yes."
However, gravity could also be one of the things in the universe that can "travel faster than the speed of light." Disregarding theoretical particles like tachyons, some string theorists believe that several objects very far apart may be able affect each other instantaneously. They can do this because their strings are connected not through 3-D space, but through another dimension.

Answer 2

Nobody knows what causes gravity only that it is caused by mass. Since light is considered both a particle and a wave i guess it would have some gravity when it is a particle. If the sun were to dissapear all the planets would go frying off. Earth not only is inpacted by gravity from the sun, but by every object that has a mass. The moon bends the earth out of shape and a star millions of miles away still attracts earth, but very insignificantly.

Answer 3

No/yes. The force would continue would according to Einstein's theory of general relativity.

However, gravity is not considered to be a "light wave". It is not considered matter and has no mass, unlike light.

Some scientists consider gravity (specifically the "gravitons" that make it up) to be the long-sought massless particles in nature.

Answer 4

easy is the two a particle besides as wave. It has photon debris with little or no weight. that's been proved in lab that easy ray bends below effect of gravity, for that reason it has mass. it is likewise a wave it relatively is why a easy via a 2" hollow will look extra effective on the wall the place it relatively is projected. besides the shown fact that, laser is a distinctive factor. A laser beam via a 2" hollow will coach diameter of optimum 2" even at a protracted distance. that's because of fact in laser, the easy capability is concentrated with the help of filtering it and scaling down wave amplitudes. easy is an electro-magnetic wave with electric and magnetic waves at perpendicular to a minimum of one yet another. it relatively is confusing to appreciate, yet easy has the two wave and with mass, in basic terms like water waves. when you consider that photon debris are very small, they are able to bypass via paper, yet no longer via wood or wall, which will take up its wave capability. many stuff interior the technological expertise works on some 'information' which no physique knows. as an occasion, no person knows electricity or the way it travels, yet nevertheless we run electric gadgets. Sir Isaac Newton declared in seventeenth century that easy is a wave. combatants asked then the way it may commute in area, in a vacuum? He theorized that inter-planetary area is crammed with a fabric referred to as ether. He extra that ehter is very easy so as that it will no longer decelerate the rotation of planets! He additionally stated that sound is the max velocity any merchandise can commute!

Answer 5

It is not a light wave, but yes it would travel like one in this case. Gravity travels at the speed of light, because nothing can exceed it. It would send out a wave (ripple) in space-time, which is like a trampoline with a wave in it.

It is a complex subject, but it makes sense. Newton's methods proved to be wrong with the speed of gravity, so it is better described with relativity.

Answer 6

Standard experimental techniques exist to determine the propagation speed of forces. When we apply these techniques to gravity, they all yield propagation speeds too great to measure, substantially faster than lightspeed. This is because gravity, in contrast to light, has no detectable aberration or propagation delay for its action, even for cases (such as binary pulsars) where sources of gravity accelerate significantly during the light time from source to target. By contrast, the finite propagation speed of light causes radiation pressure forces to have a non-radial component causing orbits to decay but gravity has no counterpart force proportional to to first order. General relativity (GR) explains these features by suggesting that gravitation (unlike electromagnetic forces) is a pure geometric effect of curved space-time, not a force of nature that propagates. Gravitational radiation, which surely does propagate at lightspeed but is a fifth order effect in , is too small to play a role in explaining this difference in behavior between gravity and ordinary forces of nature.

Answer 7

No

the gravitational force is M1 x M2 divided by r squared............

where M1 and M2 are the masses of the 2 bodies and r is the distance between them.

Answer 8

Gravity has nothing to do with light. (A little in a black hole).
