Not trolling, genuine question that I do not quite understand-

Energy equals mass times the speed of light squared. However, nothing is supposed to be able to move faster than the speed of light. Energy exists. How was mass accelerated to the speed of light squared to create energy?

you misunderstand the relationship given. the energy equivalent is proportional to the given mass multiplied by c^2. this does not in any way entail accelerating masses beyond lightspeed

Mass times the Speed of light

how the fuck can you times those two things? seriously e=mc^2 is a stupid troll equation

you can't multiply mass and velocity anymore than you can multiply apples and sound, or happiness and trees...

physicists confirmed for philosophers.

Retard.

Remember the kinetic energy equation from high school?
E = 1/2 m v^2
You're multiplying m (mass) and v (velocity) squared to get E (energy).

THE UNITS IN THE TWO FUCKING EQUATIONS ARE THE SAME.

To conclude, /sci/ is mostly populated by complete dumbasses who have no idea wtf they're talking about.

>> No.3577881

>>3577637
Its just a conversion factor indicating how much energy you can get out of a kilogram of mass in a nuclear reaction. It doesn't imply you've got to get mass to go the speed of light.

E=MC^2 is basically the kinetic energy equation with Einstein's relativistic correction for velocity being equal to zero.

You would understand this better if you were to use planck units.

Mass: (1 electronvolt/ C^2)^(1/2)
Distance: (Gravitational_constant*Reduced_Planck_constant / C^3)^(1/2)
Time: Gravitational_constant*Reduced_Planck_constant / C^5)^(1/2)
Energy: (Reduced_Planck_constant*C^5 / Gravitational_constant)^(1/2)

Using these units E=MC^2 is evident with basic algebra.

>> No.3577939

Here's the best explanation I can offer:

first understand that velocity is a unitless measure. When we talk about spacetime we must use the same units for space and time for instance light-years.

So light travels one light-year in a year hence its velocity is 1

Now any sub-luminal velocity will be a fraction of this, 0.6 etc.

So consider the equation for kinetic energy: k.e = 1/2mv^2. The units of energy are in fact the same as the units for mass.

Now momentum: p = mv. The units for momentum are also mass. Momentum and energy are parts of the same thing, much like space and time are part of spacetime.

It was not. Where are you getting such bullshit from? The equation doesn't imply anything like that.

Hey Teacup, you forgot your tripcode.

>> No.3578078

E=mc^2 doesn't imply that.

E=mc^2 is a formula that shows the relation between energy and mass.

It means, there's a fuckton of energy in mass. Even if it's just a little mass, there's a megafuckton of energy.

The formula allows you to calculate just how much in any given mass.

You left out your constants of c^2 and c^4 :P

Technically, you should be writing:
E^2 = m^2 c^4 + p^2 c^2

Unless you want to have "m" and "p" in units of energy, not mass and momentum.
