Why does massless light bend near a large mass?

Why does massless light bend near a large 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.

Does light bend space?

Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Can information escape a black hole?

Information, they now say with confidence, does escape a black hole. If you jump into one, you will not be gone for good. According to Einstein’s general theory of relativity, the gravity of a black hole is so intense that nothing can escape it.

Where does the energy go in a black hole?

While no energy can escape from beyond the event horizon around the black hole, energy is released from the material as it falls in. Accretion onto a black hole is the most efficient process for emitting energy from matter in the Universe, releasing up to 40% of the rest mass energy of the material falling in.

What information is lost in a black hole?

At one level, we can describe a black hole as viewed from a distance: the black hole is formed by collapse of matter, which eventually evaporates leaving the quanta of Hawking radiation in space. From this perspective, Maldacena’s insight holds and there is no information loss in the process.

Can a black hole destroy the universe?

Black holes are among the most destructive objects in the universe. There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process.
