You sacrifice mass to create energy (energy is just mass with a velocity), and the faster mass moves (relativity) the more massive the mass gets, is there some sort of significance to that? I hate riddles.

The question is unclear.
 
E=MC^2. Destroy mass, create energy. -1 mass +1 energy.

Lorenze Transformation equation. Faster you go (sacrificing energy, propulsion), the more massive mass gets. +1 mass -1 energy.

An answer to you riddle.

Energy is force x distance. A stationary mass has rest mass and therefore rest energy. This rest mass used energy to create it - in its structure, force moved through a distance and is stored as potential energy (PE).
When this mass moves it gains kinetic energy (KE).

Now the faster mass moves the more massive it seems to get. Well this is not an increase in physical mass, but is an effect brought about by the effects of force propagating at the speed of light. It's a bit like pushing a child on a swing. As the child moves faster, your hand has less push effect because it moves at the same speed as the swing. This doesn't mean the child's mass has increased, it only means that the effect of the push weakens.

Also when particles change type, ie, big to small, the release of potential energy gives the smaller particle more speed (PE changes to KE).

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...
