do you know what e=mc^2 means?

This is the rest energy of a particle. Energy equals mass times the speed of light in a vacuum squared. This expression became famous for its simplicity, even though it's not really all that practical. I read once that even at absolute zero particles will still have some motion. I'm not sure how one would go about proving that since it's impossible to get anything to a temperature of absolute zero. Anyway since there will always be some movement, the more practical version is:\n\nE = mc^2 /(sqrt(1 - v^2/c^2)), where v is the speed of the particle. (sqrt() is meant to mean the square root of the argument inside the parenthesis)\n\nIt's important to note that this is only true for a particle since you have to consider binding energies if you want to look at anything more complex.

I would have to say no. E=mc^2 is a version of einstein's relativity theory. It means that Energy is equal to Mass times the speed of light squared, and that there is an equivalence betwen mass and energy ( it means that no object with mass can go faster than the speed of light). But it has nothing to do with everything being made of nothing in my opinion. (see http://www.drphysics.com/syllabus/energy/energy.html)

The meaning of the equation is "energy equals mass times the speed of light (299,792,458 m/s) squared."

E(sigma) means summation.\nIf it is backwards, then it means "there exists"

E=mc^2 \nEnergy = mass * (speed of light)^2, c = the speed of light (approx. 186,000 miles per second).

E = mc2 states an equivalence between energy (E) and mass (m), in direct proportion to the square of the speed of light in a vacuum (c2). \n\nhttp://www.drphysics.com/syllabus/energy/energy.html\n\nEinstein reasoned that the center of mass of an isolated system doesn't just move on its own. So, the motion of the cylinder must be compensated by the motion of some other mass. Let's assume the light has mass m. Then, Mx=mL, since the cylinder moves x to the left and the light moves L to the right. Substituting the expression for x given above, the equation can be simplified to E=mc2.

The theoretical physics equation E = mc2 states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit specific terms, E (Joules) = M (kilograms) · (299792458 m/s) 2.

Energy = mass x speed of light squared

ja :), that's a good one. E=mc^2 talks about the equivalence between matter and energy; c is just the constant that joins them both ..you won't attain a c ¨velocity¨out of it ; you'll just have to use \n E=mc^2/(sqrt(1-(v/c)^2) ( Is it Lorenz transf?) and I think Xav was pretty clear with his explanation! :)

according to enistin yes\nthats how he came up with the equation e = mc^2 because he asked him self how would light look if you traveled at the speed of light

It means power of 10 (it's a shorthand for scientific notation).\n\nSo your equation is:\n\n(1*10^-230)*e^(0.2682*x)\n\nWhere lower case e is the mathematical constant e (2.718...).

e=mc2 is the Eienstein's famous equation of relativity. This equation only applies to very tiny particles, who can move with the speed of light. 'c' here is the speed of light which is a constant quantity. 'm' is the mass of the tiny parrticle.\nWhen a tiny particle moves with a velocity which is the square of velocity of light, it produces energy.\n\nSo, you might wonder why the solar energy is so poweful that we can even run a car.

the equation is as simple as the elegant and simple universe.the equation means that any type of energy can be converted into mass and vice versa. it means that at speed of light the enrgy becomes infinite(to accelerate it actually)and thus mass becomes infinite(special relativity)provided the generation of light in both the cases. the actual equation is e(kinetic energy)=mc^2/underroot(1-v^2/c^2).the e=mc^2 equation is still applicable for objects moving or stationary meaning that both the equations are true.
