If Nothing Can be faster thab light, then how come energy is the square of light?

Question

There is a fact saying that nothn the universe may exceed the speed of light. But, is this not disproved by the fact that energy is simply matter which is traveling at the speed of light squared? I understand the equations do not technically mean this but then again wat is energy if not extremely velocified matter?

I knw the formula does not indicate that mattr does not travell at this speed to attain the energy coz it is already there but if matter were to travel at that speed, would it be only energy and no longer matter??

Answer 1

You have asked an important question. The answer lies in an abstract thought and then an answer. There is another manner of answering your question but it is too long. Were you to check out http://360.yahoo.com/noddarc "Concepts concerning Gravity, Time, and Energy" you'll have a more complete answer.

To begin we need to consider what the value of c^2 means. This is found three times in the physics trilogy: E = mc2, m = E/c2, and c2 = E/m. The last equation is that for a field of gravity or that of a field of time. The "c2" expression is that of a relationship between energy and mass. There is an interesting thought; Stephen Hawking in "A Brief History of Time," page 92, paragraph 3, states; "Like light, gravitational waves carry energy away from the objects that emit them". Which means that the force of gravity is of a particular from of energy, and itself is derived from another form of energy. So when we consider the value of "c2" it is not just an abstract concept that keeps all things sorta tidy, it is a reality. Along this same thought, consider that our sun expends 665 lbs/sec in form of gravity in order to keep the planets in place, and our own planet expends 0.00444 kg/sec in order to keep us where we are supposed to be.

Lastly is the concept of c^3, which is a cube of physical time. As I remember, were time to be cubed it is equal to l kg. or 2.2 lbs. This should not be surprising when considering the first two equations of the physics trilogy. In the first, the basis of the existence of that concept "c2" is the multiplier, whereas in the second it is the divider. In each of these thoughts we find the basis of their existence to be that of "c2". c^2 is what our universe is composed of. All forms of energy and mass have as their basis this value. There is nothing in our universe that is not totally composed of this value, and nothing is able to exist to us that is not totally composed of it.

Answer 2

This is a really good question. The formula E = mc^2 came directly from KE = mv^2, where v is the velocity. In this case, the velocity is just c, the speed of light. I think that matter cannot actually reach the speed of light. However, energy can. In nuclear physics, it has been observed that matter can be directly and absolutely converted into pure energy, so perhaps this is the only way "matter" can "travel" at the speed of light. So if teleportation or stargates was to become a reality, then that would probably be how it would be done.

Answer 3

Energy is NOT matter traveling at the speed of light.

What does E=mc^2 mean?

It means that an object at rest with mass m has an intrinsic energy E, which equals the mass times the speed of light squared. This rest mass energy can sometimes be liberated and turned into other forms of energy (as in a matter-antimatter annhilation).

c^2 is just a constant of proportionality in that equation. The mass is not traveling at the speed of light.

Answer 4

The speed of light is just a quantity -- that's all it is. In the case of matter, even when it's at rest, its energy is equal to its mass times the speed of light squared. It doesn't mean that the mass would have to "travel" at the speed of light squared in order to attain its energy. The energy is already there.

Answer 5

No, that's not what the formula E=mc² means. The formula means that a chunk of matter has that much energy, whether it is moving or not. The fact that a speed appears in a formula does not necessarily imply that something is actually moving, or is moving that fast.

Answer 6

My Lay mans explanation;

C square means all quantity of light that is propagating in all three dimension of space. (space is squared)

Or in other word, A certain amount of mass (quantity) that turned into light energy is propagating from the source to all directions in space which is a square of the distance. And, the distance is about 186,282.397 miles.

Remember that E=mc2 is a quantitative formula of the mass equivalent to the amount of light. Since the light is propagated in space, We have to measure its quantity from the distance from point of source to the distance it traveled.

So therefore, the C2 in the formula is not a presentation of light speed but just a distance\squared.

Answer 7

No the value of the speed of light in E=mc^2 is a scalar - it has magnitude but no direction. When looking velocities you then consider motion e.g. 0.5c as a vector.

Answer 8

E=mc2

E is the value of the energy. There is a relation between this value and speed of light.

I dont believe light speed is the limit, but this law is only about the value of energy and not about the speed as a velocity but as a natural contant value like plank's and others.
