If I want to travel faster than light, why can't I just

>>8568580
Also how can a photon travel at all if you can't divide by zero?

>lowercase e for energy

Because that's an equation which is only valid for zero velocity. The proper equation is
[math]\displaystyle E=\frac{mc^2}{\sqrt{1-\beta^2}}[/math]
where [math]\beta[/math] is the velocity relative to the speed of light. Solving for the velocity, you find
[math]v=c\sqrt{1-(mc^2/E)^2}[/math] which approaches the speed of light asymptotically as the energy becomes large.

Excuse my failure to use in-line latex. Beta is v/c.

>>8568587
Again, because you're not seeing the full picture. Mass isn't properly defined for that situation, but momentum is.

Why isn't this taught in schools?
I haven't taken uni phys, but even in AP phys it was always "muh E=mc^2"

>>8568587


According to all known laws
of physics, there is no way a photon
should be able to move Its duvision by zero is too impossible to get its fat little body off the ground. The photon, of course, moves anyway because photons don't care what humans think is impossible

More seriously and mêmes apart, this isn't taught in school because those in charge of school programs think of students a brainless monkeys that should be force fed knowledge (at least where I live)

>Why isn't this taught in schools?
Because educationists and politicians think children are too dumb to understand it, so they remove anything modern from the curriculum.
It is taught in "advanced" classes like honors or AP, however. If you took AP physics at a decent school you probably should have seen this, at least in passing.

Unfortunately, teaching highschoolers about spacetime and Lorentzian metrics is probably a bit too much for the last week or so of their semester, so it's unlikely that a full demonstration of special relativity will ever appear at the gradeschool level. The curiosity at this point is what drives many people to major in physics at uni.

At which point they don't see it until Modern Phys. II Junior year.

Sophomore year for me, and by that time I had picked up a few books from the library and talked with more senior students. Uni isn't what people expect it to be, sure, but that doesn't mean it can't exceed those expectations.

Because e=mc^2 is most often brought up to talk about mass-energy equivalence, not FTL.

How exactly the fuck do you intend to increase energy without increasing mass?

Don't say increase kinetic energy, that will also increase mass as you approach relativistic speeds

>>8568767
>increasing mass
This is an outdated interpretation.

Protip : e = mc^2 is an approximation.

Ah, and also it is not said that nothing can go faster than light.
The claim is that there is a speed limit that cannot be exceeded, which is likely the speed at which light travels.
