The first question that should come to mind when you’ve got a new theory that’s, honestly, is “why didn’t anyone notice this before?” Why is it that the only part of the energy that anyone ever noticed was ? Up until Einstein that fastest things around were bullets moving at about the speed of sound.Here’s the idea; energy is distance times force (E=DF), and force is mass times acceleration (E=DMA), and acceleration is velocity over time, which is the same as distance over time squared (E = DMD/T or something like that, and still have the units correct.It may even be possible to mix together a bunch of other universal constants until you get velocity squared, or there may just be a new, previously unknown physical constant involved.The answer Einstein came up with was , which is time as measured by clocks on the moving object in question. By the way, as measured by every one else on the planet, you’re currently moving through time (t) at almost exactly 1 second per second ().One of the most important, simple things that you can know about relativity is the gamma function: .“Spacetime rotations” (changing your own speed) are often called “Lorentz boosts“, by people who don’t feel like being clearly understood.You can prove that the spacetime interval is invariant based only on the speed of light being the same to everyone.
One kilogram of matter holds the energy equivalent of 21.4 Megatons of TNT, or about 1500 Hiroshima bombs.It’s a bit of a tangent, so I won’t include it here.() Some difficulties show up in relativity when you try to talk about velocity.(This used a slight breach of notation: “” is a velocity of the velocity, or “speed”) The amazing thing about “spacetime speed” is that, no matter what v is, .(Quick aside; it may concern you that a squared quantity can be negative.
