If you are traveling at the speed of light and you were to shine a light the observer wouldn't observe twice the speed of light? Please explain this phenomena to me
The theory of relativity, developed by Albert Einstein, is a fundamental concept in physics that explains how time and space are relative to the observer's frame of reference. It states that the laws of physics are the same for all observers in uniform motion and the speed of light is constant in all inertial frames of reference.
Special relativity deals with the relationship between space and time in the absence of gravity, while general relativity takes into account the effects of gravity on space and time. Special relativity is based on the concept of frames of reference, while general relativity explains how massive objects affect the curvature of space-time.
The twin paradox is a thought experiment that demonstrates the effects of time dilation in special relativity. It involves two twins, one stays on Earth while the other travels in a spaceship at high speeds. The traveling twin experiences time dilation, meaning time moves slower for them, so when they return to Earth, they are younger than the twin who stayed on Earth.
The speed of light is approximately 299,792,458 meters per second and is constant in all frames of reference. This was first predicted by Einstein's theory of special relativity and has been confirmed by numerous experiments. The constancy of the speed of light is a fundamental principle in the theory of relativity.
In general relativity, gravity is explained as the curvature of space-time caused by massive objects. Light, which travels through this curved space-time, appears to bend when it passes near a massive object, such as a star. This phenomenon is known as gravitational lensing and is a direct result of Einstein's theory of relativity.
