We sometimes hear of things that can travel faster than light. Something called 'the speed of thought' is occasionally proffered. This is an exceptionally silly notion especially since the speed of impulses through the neutrons in our brain is about the same as the speed of a donkey cart.

As the pattern of events is unaltered by motion, the mechanism must be the same when the electron is in motion as when it is at rest. But experiment shows that an electron in motion exerts additional forces which are not the same for all directions in space; if we picture this electron as moving head-foremost through space, these forces surround it like a belt around its waist.

At electric speed, all forms are pushed to the limits of their potential.

to travel faster than a speeding bullet is not much help if you and it are heading straight towards each other

Everything is already moving so very fast, but you need a great deal more speed than this to escape the earth's gravitational pull. Seven miles per second. More fuel, please.

Neither matter, nor energy, nor anything capable of being used as a signal can travel faster than the speed of light. This limitation of the speed signalling to 299,796 kilometres a second seems a rather arbitrary decree of Nature.

60,000 kilometres per second may be the practical (!) speed limit for space travel

The drumbeat of the electrical transportation is accelerating like nothing I've ever seen in my life.

Inflation itself proceeds at a speed faster than the measured speed of light.

if a shower of electrons is shot on to a zinc sulfide screen, a number of flashes are produced - one for each electron - and we may picture the electrons as bullet-like projectiles hitting a target. But if the same shower is made to pass near a suspended magnet, this is found to be deflected as the electrons go by. The electrons may now be pictured as octopus-like structures with tentacles or 'tubes of force' sticking out from it in every direction.

Acceleration is the rate of change of . ...The units are ...velocity per unit time, or distance-per-time per time. ...[F]alling bodies ...near ...earth fall with an acceleration or 9.8 meters-per-second per second ...after the first second ...falling at speed ...9.8 meters per second, after two seconds... 19.6 ...and so on. [T]he units of velocity are length/time... and units of acceleration... (distance/time)/time, or equivalently distance/time² ...[T]he acceleration near... Earth would be written 9.8 m/sec² for short.

It was big, it was heavy and it tended to be slightly underpowered,” Lohrenz says. “You’re coming across the back end of that aircraft carrier, going about 165 miles an hour, and you slam down on that deck and come to a complete stop in just under 1.2 seconds.”

Most people now, when I say particle accelerator, think of... the bohemoth. This is the . It is almost 27 km in circumference, which is why the tunnel looks almost straight. It's about 100 meters underground, over the border between France and Switzerland. ...Inside these magnets here, these big blue long ones it's one of the coldest places in the universe at 1.9°K above . ...[I]t accelerates two beams of s, from inside the atom, in opposite directions at 99.99999% (that's the exact number) of the speed of light and smashes them into each other... [I]t is what I like to call an impressive shiny huge piece of kit that's bigger than everyone else's!

Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.
