Is lighting caused by gravity?

Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time. As for how much gravity, it would depend on how much energy. Once you have the mass, E = M*c2, where c is the speed of light (300,000 km/second), and E is the energy.

Does light ignore gravity?

Light is massless (m = 0), and therefore all the masses in all the Universe can exert no force on it. Anything, no matter how great, multiplied by 0 is still equal to 0.

Does light curve?

Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. Out in space, light rays passing near very massive objects such as stars are seen to travel in curves.

Is Thunder caused by gravity?

Examples of trigger mechanisms that produce gravity waves are mountains and thunderstorm updrafts. To generate a gravity wave, the air must be forced to rise in STABLE air. Why?

Does light slow down due to gravity?

Answer: The short answer is no, the speed of light is unchanged by gravity. If for example light travels from a distant star to Earth and passes by a black hole, the path of the light will get bent as it passes by the black hole, which will lengthen its travel time. The actual speed of light, though, is unchanged.

How does light have energy but no mass?

Light indeed carries energy via its momentum despite having no mass. In contrast, for a particle with no mass (m = 0), the general equation reduces down to E = pc. Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.

Can light bend by itself?

But now researchers have shown that light can also travel in a curve, without any external influence. The effect is actually an optical illusion, although the researchers say it could have practical uses such as moving objects with light from afar. For light to bend by itself, however, is unheard of—almost.

Can gravity cause tornadoes?

If a gravity wave hits a rotating thunderstorm, it can sometimes spin that storm up into a tornado. Gravity is what keeps them going. If you push water up and then it plops back down, it creates waves. It’s the same with air.”

Why is light attracted to objects with mass?

But experiments have shown that in fact Newton was wrong and light IS attracted towards object with mass, as Einstein’s theory predicted. According to Newtonian gravity, light is not affected by gravity, as light is massless. Einstein’s law E = mc 2, immediately suggests that light is affected by gravity.

Is light affected by gravity?

It’s also interesting because there is some sense in which light does have “mass” (and therefore should be influenced by gravity… read on!) In our everyday experience, light seems to travel in straight lines, unaffected by gravity.

Does gravity attract anything?

In simple terms no, Gravity does not attract anything as it’s not a Force. According to Einstein, Gravity is a property of SpaceTime and merely caused by bending of SpaceTime around objects. These objects when massive like a Planet , Star or a Black Hole bend SpaceTime to varying extents in increasing order based on their own mass.

Does light bend in a gravitational field?

But that bending is not gravitational; it’s electromagnetic. However, light does bend when travelling around massive bodies like neutron stars and black holes. This is explained by Einstein’s theory of general relativity. We are all familiar with massive objects being influenced by gravity.
