how does light behave

In daily life, we observe how light travels in straight lines without being affected by gravity. We see how it refracts as it crosses the boundary between two mediums, air and water. This is why objects like straws in a glass of water appear crooked. However, as he explains, it’s a breakout. 24 Channelsoccurs not under the influence of gravity, but under the influence of electromagnetic forces.

But when light passes near massive objects such as neutron stars and black holes, it is bent, as Einstein’s general theory of relativity explains. According to this theory, space-time distortion caused by gravity affects the orbit of objects, including light. Objects, including light, instead of moving along straight lines, move along special “lines” in curved space-time called geodetic lines.

Since light also travels along geodetic lines, even if it has no mass, its path is also bent by gravity. This concept challenges our traditional understanding of gravity as a force that acts only on objects that have mass.

Light can also affect objects

Recent research suggests that light can also distort space-time in a similar way to gigantic objects. This phenomenon is known as gravity of light itself. The idea is that because electromagnetic waves, including light, have energy and momentum, they must bend space-time, albeit in a tiny and odd way.

Consequently, the distortion of space-time created by light can affect the propagation of light, as predicted by the equations of general relativity.

This fascinating concept sheds new light on our understanding of gravity and its interaction with light. It challenges our traditional ideas about mass and gravity and opens up new possibilities for exploring the mysteries of the universe. Scientists continue to study this phenomenon, conducting experiments and observations to reveal even more subtleties of gravity’s effect on light.

That is, although light has no mass, it is affected by gravity due to the distortion of space-time caused by massive objects. Einstein’s general theory of relativity provides a framework for understanding this phenomenon, and recent research suggests that light itself may contribute to the distortion of space-time.
