E=MC2: Consequences of Being Wrong

[whatzzupboy]

If E=MC2...

What would be the reprocutions if Einstien's e=mc2 was found to be wrong.

 

[chroot]

Neither nuclear reactors nor nuclear bombs would work. Oh, and the Sun wouldn't work either.

Yea ok nuc plant and bombs along with countless other things wouldn't work but think about it E=MC2 says speed of light is equal to at best 50% the speed of light how is that be? Specialy since light is suppose to move in waves yet some how it is present in a vacume, how? Wouldn't that imply the light is some kind of organized energy?

 

[chroot]

E = mc² doesn't say anything at all about light being 50% of anything -- and I have no idea what makes you think it does.

E = mc² says that the mass and energy are equivalent; that's all. In units were c = 1 (time measured in seconds and distance measured in light-seconds, for example), the equation is just E = m.

And since your poll doesn't make any sense, I have closed it.

Indeed =x I looked at it for like a minute before scrolling down, 'cause I thought there was something I missed =x

E = mc² says that the mass and energy are equivalent; that's all.

IMHO - That has no meaning for me. It'd be like interpreting the equation E = hf as saying that frequency and energy are equivalent.

E₀ = m₀c² says that if a body radiates energy in the amount E then its proper mass m₀ will be reduced by the quantity E₀/c².

E = mc^2 its a general equation. E = hf its not... Its valid for a photon. It says that the energy of a photon is equivalent to its frecuency.

 

[Artman]

If E=MC^2 was wrong, we would not observe predictions from occurring as expected, as in chroot's example, nuclear bombs woudn't work, etc.

Einstein thought long and hard about this equation, basing it on observations and making predictions that have shown its accuracy.

It would be kind of like saying what if Newton was wrong? We couldn't calculate projectile motion or determine ahead of time how fast something will be moving when it hits the ground when dropped from a known height. If Newton was wrong would the object just float there?

E=mc^2 isn't that 'general' either. It is only correct if the momentum of the object is zero. The general relation is:

$$E^2=m^2c^4-p^2c^2$$
