Any mass accelarating @ 'c' is light

In summary, the conversation discusses the relationship between mass and energy, specifically when mass is accelerated to the speed of light. It is clarified that mass does not turn into light when accelerated to this speed and that they are two distinct realms. The value of c^2 is also discussed and how it relates to the speed of light. It is noted that in conventional units, c is dimensionless, while in other systems of units it has a numerical value and dimension. It is also mentioned that there is no way to accelerate to or from the speed of light.

""any mass accelerating @ 'c' is light ""

hii everyone, from E=mc^2 I've seen that "When mass accelerating @ c , its simply called energy".


( light speed is constant everywhere nothing can cross that limit. So, c^2 is considered as c , in fact c^2 is for dimensional accuracy)



so, my doubt is :When mass accl to 'C' , can we say that the resultant energy is LIGHT?

If I understand your question correctly, no, mass doesn't turn into light when accelerated to the speed of light. Infact, they are two distinct realms. There are particles with mass that can never achieve the speed of light. Then there are particles, with photons being one example, that are massless that travel exclusively at the speed of light.

c2 isn't a speed. In conventional units, such as http://en.wikipedia.org/wiki/International_System_of_Units" , which are handy for relativity, length and time are considered to have the same dimensionality, so c is a dimensionless constant. In geometric units, c is set equal to 1, so c2 also equals 1. But in other systems of units, c2 has a different numerical value to c as well as a different dimension.

As Pengwuino says, something is either traveling at speed c (as measured in what's called an "inertial frame of reference") or not. There's no way to accelerate from another speed to c, or from c to any other speed.

What does it mean for any mass accelerating at the speed of light to be considered light?

When a mass is accelerating at the speed of light, it means that it is moving at the fastest possible speed in the universe. Light is also known to travel at this speed, so any mass moving at this velocity can be considered as light.

Is it possible for any mass to actually accelerate at the speed of light?

According to Einstein's theory of relativity, it is impossible for any mass to reach the speed of light. As an object approaches the speed of light, its mass increases infinitely, making it impossible to accelerate further.

Why is it important to understand the concept of mass accelerating at the speed of light?

Understanding this concept can help us understand the fundamental laws of the universe and the nature of light. It also plays a crucial role in fields such as astrophysics and space travel.

How does the acceleration of a mass at the speed of light affect time and space?

According to the theory of relativity, as an object approaches the speed of light, time and space become distorted. This phenomenon is known as time dilation and length contraction.

Can any object with mass travel at the speed of light?

No, according to the theory of relativity, only massless particles such as photons can travel at the speed of light. Any object with mass would require an infinite amount of energy to reach this speed, which is impossible.
