How does gravity bend light if it has no mass?

Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law. Photons can be pulled by gravity not because of their mass (they have none) but because gravity bends space-time.

Is gravity a force or curvature of spacetime?

Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.

How does gravity bend space-time?

Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

Is gravity a dimension?

Gravity is not a dimension. It is a fundamental force which is weakest among all the force. This whole process is called as Doppler shift.

Does gravity require extra dimensions?

This theory requires that the fields of the Standard Model are confined to a four-dimensional membrane, while gravity propagates in several additional spatial dimensions that are large compared to the Planck scale. String theory has one notable feature that requires extra dimensions for mathematical consistency.

Can gravity exist without mass?

The only way to get gravity is with mass. The more mass, the more gravity you get. Without mass, you can’t have gravity.

Does gravity have mass?

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

Is gravity a force?

gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.

Is gravity the 4th dimension?

Gravity, electricity and magnetism are the 4th, 5th and 6th Dimensions of corporeal reality as measured with the right angle rule, plane and solid geometry, and metric mathematics. Note that these unprecedented conclusions are simply renewed recognitions of what was and is already known.

What is the dimension of gravity?

Gravity is not a dimension. Neither gravity nor gravitation are dimensions. An alternative view; Gravitation is a property of all-encompassing universal medium that fills entire space outside basic 3D matter-particles.

What is the definition of gravity?

Gravitation is a property of all-encompassing universal medium that fills entire space outside basic 3D matter-particles. Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth.

Why do objects with more mass have more gravity?

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight.

Why is gravity stronger at a deeper Bend?

The deeper the bend the stronger is the surface tension which implies huge density. Gravity is nothing but a consequence of the layout of space and time like say you define the bending of a rubber string when a mass object is hanged from it. It is nothing like a dimension. Gravity is not a dimension.
