Default A change of speed of light

It would improve our ability to space travel because the universal
speed limit would be higher.

There's a knob on the wall in my office that's set to 137. Shall I turn
it and see what happens?


It you weren't supposed to turn it, it wouldn't be a knob.

You've made his point, ****head.

So would changing the conversion factor between miles and kilometers,
since that would enable us to drive as fast in the US as they can in
Europe. 70 mph would be *screamin' fast*.

The German autobahns have no speed limit. Drive as screamin'
fast as you dare and have horses to do so.

Mess with coupling constants at our own peril!


Right. The last time I fiddled with it, we lost an entire planet (poor
Pluto).

xxein: Maybe you should have asked how the 'coupling constant'
converts with the addition of velocities.

That is more than the speed limit in New Zealand.

Your logic is backwards: a higher universal speed limit would make it
HARDER for space travel -- in fact: impossible.

The extreme cases (infinty for Newtonian physics, c for relativity)
clearly show this as follows. At a steady 1-G acceleration, it would
take tens of thousands of years to get around the galaxy in the former
case. In the latter case, with a finite speed limit of c, at a steady
1-G acceleration, it would take about 20 years or so go get virtually
ANYWHERE.

At an even more extreme: if c were almost 0, you could get anywhere in
almost no time at all!
