or is it greater (though it may be very small difference) than the normal
speed of light?
'C' refers to the speed of light, which is a fundamental constant in physics. It is important because it serves as the universal speed limit in the universe and is a key factor in many theories and equations in physics.
No, 'C' is not faster than light. In fact, 'C' represents the maximum speed at which any object can travel in the universe. This is known as the speed of light barrier.
According to our current understanding of physics, nothing can travel faster than the speed of light. Some theories, such as the concept of wormholes, suggest that it may be possible to travel faster than light by bending space-time, but this has not been proven.
The mystery surrounding 'C' stems from the fact that it is a fundamental constant in physics, yet we still do not fully understand its nature. It is also a key factor in many unsolved problems in physics, such as the unification of general relativity and quantum mechanics.
'C' is typically measured using sophisticated instruments, such as lasers and mirrors, which can accurately determine the distance light travels in a given amount of time. This is known as the speed of light experiment and has been refined over the years to provide increasingly precise measurements.
