Exploring the Possibility of e=mck and h.nu Proportional to mc

[GautamAishwarya]

when theory of relativity declares speed of light to be the limit for speeds of all matter and energy and information. then, how can einstein in his mass-energy eqn talk about c squared. we can't talk about any velocity more than c.
it is possible that e = mck where the value of constant k shall be equal to value(only of magnitude only) of c.
also ,
h.nu is directly proportional to mc, and ratio of h.nu to mc is the constant with value equalling c.

Don't confuse arithmetic with physics. c is a number (with units). It happens to be the speed of light but it is just a number. c² is another number that is NOT the speed of light. In fact, since c² has units of length²/time², it cannot be the speed of anything. If you want to say "the value of constant k shall be equal to value(only of magnitude only) of c", fine (well, not "magnitude only" because you have to take the units into account), but that was what was meant all along.

First of all, it is important to understand that Einstein's mass-energy equation, E=mc², is a fundamental principle of the theory of relativity. It states that energy (E) and mass (m) are equivalent and can be converted into one another, with the speed of light (c) as the proportionality constant. This equation has been proven to be accurate in numerous experiments and is a cornerstone of modern physics.

Now, to address the concern about the speed of light being the limit for speeds of all matter, energy, and information, it is important to understand that this limit only applies to objects with mass. The speed of light is the maximum speed that any object with mass can attain, according to the theory of relativity. However, this does not mean that all forms of energy and information are limited by the speed of light.

For example, photons, which are particles of light, have no mass and can travel at the speed of light. This is why the equation h.nu (where h is Planck's constant and nu is the frequency of the photon) is proportional to mc, as both sides of the equation are describing energy. The ratio of h.nu to mc is simply a constant, and in this case, it is equal to the speed of light.

In the same way, the possibility of e=mck, where k is equal to the value of c, is not contradictory to the theory of relativity. This equation simply shows the relationship between energy, mass, and the speed of light, and does not imply that anything can travel faster than the speed of light. It is important to remember that the value of c in this equation is not a velocity, but rather a proportionality constant.

In conclusion, Einstein's mass-energy equation and the concept of the speed of light being the limit for speeds of matter and energy are not contradictory. They are both fundamental principles of the theory of relativity and have been proven to be accurate in numerous experiments. The possibility of e=mck and h.nu proportional to mc is simply a way to express the relationship between energy, mass, and the speed of light.
