is light following the curvature of spacetime or is it attracted to gravity?

Question

when gravity curves spacetime light bends into the curvature but could light be attracted to the light rather than following the curvature. Because space if you really think about it it is nothing it is just empty space so when the light bends in spacetime it just looks like it is bending for no reason because you cannot see the curvature. So can you give as many reasons why the light is not attracted to the gravity. Thank you.

Answer 1

Light is following the curvature of Space-Time.

Answer 2

It's actually the bending of light by gravity that shows us that space IS curved by mass. In the Newtonian view, gravity only works on objects that have mass. Light has no mass and therefore shouldn't be bent by gravity at all. Because it is (and this has been verified experimentally: http://undsci.berkeley.edu/article/0_0_0/fair_tests_04 ) then there must be something more going on than was previously imagined.



As it turns out, it's not just light whose path gets bent by the curvature of space around a massive body. EVERYTHING'S path gets bent. In fact, Einstein showed that when an object's trajectory is curved toward a massive body (such as the Earth) that the object is REALLY moving in a locally straight path through curved space. Now if that's not enough to blow your mind, I don't know what is.



So yeah, space is curved by mass. Light travels a locally straight path through curved space, giving the effect (to those of us living in that curved space) of being bent by gravity.



I hope that helps. Good luck!

Answer 3

Light follows the spacetime curvature

Answer 4

The reason I think light isn't just attracted to the gravity is because it causes the light to bend away from the gravitational field, not toward, If the light was just attracted to it it would bend toward the object causing the distortion. Also there is no such thing as empty space, it just seems that way because we can't observe what is going on. Even in "empty space" there are always particles of matter and "anti-matter" popping in and out and wiping each other out on an atomic level.

Answer 5

I have given this idea much thought. When a super giant star collapses to form a black hole the gravitational force of the black hole will be the same as that of the star it formed from. There is a major difference between the two, the black hole will have an event horizon, the star did not. Another difference is size, the star was huge, the black is tiny. With all of that mass concentrated in such a small area I believe that the gravitational force field is so strong that even light follows it near the surface of the black hole. This force field decreases in intensity as distance from the black hole increases, much like the static pressure of an atmosphere decreases with altitude. Gravity fields exist everywhere in the universe, I believe that light propagates through these fields. This can account for gravitational lensing.

Answer 6

Both for they are essentially the same.



Light follows the curvature in space-time. Curvature in space-time is caused by gravity (the presence of matter-energy).

Answer 7

It follows the curvature of spacetime...i can't tell you it isn't attracted to gravity because its hasnt been proven.

Answer 8

firstly gravity doesnt impact mild (or photon) in any respect. 2nd element is photon has have been given some mass regardless of if it is negligible. If gravity impacts the sunshine as you says then Jupiter that's 5th planet from sunlight and that's greater greter in length and gravitional tension than the different planet in our image voltaic equipment can charm to mild from sunlight actual by using his large gravitional tension, yet my pal actuality is distinctive. Jupiter gets very nigligible mild from sunlight while in comparison with earth in spite of the undeniable fact that it has greater advantageous length and gravity. in short gravity does not impact mild (or photons) and photons at the instant are not something yet very small debris that are everywhere in our image voltaic equipment.
