Gravity is caused by energy, not mass

E=MC²

Something something energy is mass something. [/troll]

Anyway, it doesn't matter, because light is waves and waves are mass-less. Thus, light moves at the fastest possible in a vacuum and is impossible for something with mass to move faster than something without mass(in a vacuum; chernov radiation is fucking amazing).

That's actually not correct either. Light shows wave/particle duality about as much as most fundamental things.

In fact, the only thing that can really be said as to why is that "gauge bosons that do not interact with the higgs mechanism do not have mass", which light (and gluons) count as.

I could've sworn I've seen this conversation 20 pages earlier...

lol that's wrong, actually E=sqrt((MC²)²+(PC)²), where P = particle's impulse, M - rest mass, E - energy, C - speed of light. That's a formula you get almost straight out of Lorentz transformations btw, so it's pretty goddamned solid.

I'm too tired to figure out what the Particle's impulse actually means. Is it essentially the same as the momentum of the particle or is there a difference?

The hivemind communicates to me through Cherenkov radiation, which tastes like strawberries actually.
Btw through experimentation I have conclusive proof that the hivemind has granted me the power of levitation. However your puny earth science is not equipped to measure the forces involved, something about "no change in velocity outside of the measurable resolution of instrumentation used".

The topic got quantum entangled and passed through time.

Momentum is a property of a system. By applying an unbalanced force you change the momentum.
Impulse is the integral of the applied force over time. I.e., it's the measure of the change of momentum.
Both impulse and momentum have the same unit measure.
It's the same type of relation as between energy(=~ momentum) and work (=~ impulse).

That said, I'm not sure why Sergarr said impulse there - it should be momentum as the equation describes energy content, not how it changes.

[Descan]

Is impulse to momentum how acceleration is to velocity?

[Il Palazzo]

Acceleration is the rate of change of velocity. The rate of change of momentum is force.

As was said, impulse is to momentum like work is to energy.

SEMANTICS, Light's relative mass, and the whole QUANTUM PHYSICS

That's because in Russian language, the word for "momentum" is literally "impulse"

yes I meant momentum here

In glorious Soviet Russia, you do not impart momentum,  momentum imparts you!

(Also reminds me of "water sheep", as seen used in engineering projects.)

Speaking of Russia, President Putin has plans to make Star Trek real. According to the Russian newspaper Kommersant, the Russian government wants to spend multiple billions on a research program that will not only result in the development of a 'patriotic' programming language, but by 2035, is also meant to provide a functional teleportation system.

The newspaper cites Aleksandr Galitski, from Almaz Capital, an investman firm that mostly invests in the technology sector: "About the teleportation; it might seem fantasy at this moment, but at Stanford, there has already been a succesful experiment which teleported molecules over a small distance."

Scientists at the university of Delft succeeded last year in teleporting information carrying particles over a distance of 1.3 kilometers. This technology could be used in the future to send data that cannot be hacked.

Russian scientist are also operating in that field. But insofar, the announcement of the project mostly met with mocking tweets from Russians.
"37 million Russians still have a toilet cabin out in the backyard. And the government wants to spend 10 billion rubles on teleportation?"

They should hire Dahir Insaat.

Still better than Putin's science project to make anime real

'patriotic' programming language

We already have one, it's called 1C. It's exactly as horrible as you'd imagine a programming language where literally every command word from English is replaced with its direct translation into Russian would be.
