# Exploring the Mystery of 'C': Is It Faster Than Light?

• aby001234
In summary, the speed of light, also denoted as 'c', is a constant value that does not change no matter how fast an observer is moving. This is one of the fundamental principles of special relativity. Whether measured by passengers aboard an airplane, onlookers on Earth, or aliens passing by at a high speed, the speed of light remains the same at 300,000km/s. This value is derived from the solution to the wave equation for E and B fields.

Is it same as 'c'?
or is it greater (though it may be very small difference) than the normal
speed of light?

The speed of light is 'c' no matter how fast an observer is going. That's one of the guiding principals behind special relativity.

Passengers aboard airplane measure it as 300,000km/s (c).
Onlookers on Earth on measure it as 300,000km/s (c).
Aliens passing by overhead at .9c measure it as 300,000km/s (c).

the speed of light comes from the solution to wave equation for E and B fields.
And then number is constant.

## 1. What is 'C' and why is it important?

'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.

## 2. Is 'C' really faster than light?

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.

## 3. Can anything break 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.

## 4. Why is it a mystery?

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.

## 5. How is 'C' measured?

'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.
