Does anyone know the relationship between m, mass and c, the speed of light ? Can anyone draw the graph for me ? Thanks !

Welcome to PF Sunanda!

I am having difficulty understanding your question. c is constant for all frames of reference. Mass can be anything. What makes you think there is a relationship between them?

Oh ! Sorry for the misleading question ! What i meant, is, C is only achievable when m = 0, and when m increases, how does it affects C ? Hope you can understand my question now. I'm bad at interpreting
 
Okay. I'm changing my question. I'm confused with C just now. What i actually meant is, the maximum speed achievable.
E.g. , when m = 0 , highest v possible = C
 
There's no relationship of the sort that you're looking for. Massless particles move at speed c always; massive particles can move at any speed between zero and c.
 
Thread 'Can this experiment break Lorentz symmetry?'

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...

Thread '1-Way Speed of Light'

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...

Thread 'Relativator (Circular Slide-Rule): Simulated with Desmos - Insight'

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)...
