What do the variables M and C reffer to, in the equastion E=MC^2?
whatzzupboy said:ok well I am basing the equastion out side the universe so... what then is C?
irrehaare said:i thought that it depend on the environment where is the light, so the velocity of light in air is different than in water or glass . see more about diffraction of light

whozum said:Outside the universe? Wheres that? Why would there be light there?

Pengwino said:c = the speed of light in a vacuum, ~300,000km/s
Do you know what "~" means?whatzzupboy said:i thought the speed of light was 299,292.6Km/S
HallsofIvy said:You've been told what c is several times now. (And that "out side the universe" makes no sense.)
Did you mean "outside the atmosphere" (i.e. in vacuum) rather than "out side the universe"?
Do you know what "~" means?
xFlankerx said:Owned. But I thought the "C" was the speed of light in meters which would make it ~300,000,000 m/s. What difference does it make? In multipling, you would be multipling by 300,000,000 instead of 300,000.

Btw, I'm not sure I understand your post. When you say "What difference does it make?", are you saking yourself a question and then answering it, or are you really asking that question? Cuz my answer would be: "In so far as every unit system is as good as any other, it makes no difference wheter you take 'c' to be 300,000 km/s, 300,000,000 m/s or 1 M/s, where I have define the lengh 1M to be equivalent to 300,000,000 m (I heard this is what particle physicists use as the unit of length in their calculations)
HallsofIvy said:Oh, dear! I completely missed the "missing" 000!

The equation E=MC^2 is known as the mass-energy equivalence equation and is a fundamental concept in physics. It states that energy (E) is equal to the mass (M) of an object multiplied by the speed of light squared (C^2).
The equation E=MC^2 was created by Albert Einstein in 1905. It was first introduced in his paper "Does the Inertia of a Body Depend Upon Its Energy Content?" published in the journal Annalen der Physik.
E=MC^2 is significant because it explains the relationship between mass and energy. It showed that mass and energy are two forms of the same thing and can be converted into one another. This led to the development of nuclear energy and has had a major impact on modern physics.
Yes, E=MC^2 can be applied to everyday life in various ways. For example, it is used in nuclear power plants to generate electricity and in medical imaging techniques such as PET scans. It also plays a role in the production of nuclear weapons and in understanding the behavior of stars.
E=MC^2 is definitely one of the most famous equations in physics, but it is not the only one. Other notable equations include Newton's second law of motion (F=ma) and the law of universal gravitation (F=G(m1m2)/r^2). However, E=MC^2 is often considered the most famous because of its groundbreaking implications in the field of physics.
