Infinite acceleration?!

[Troll King]

Be careful when you bring in an example moving at the speed of light. That's when regular thinking doesn't always work.

omg i just changed my mind again!

based on the proofen fact that a(t) is the derivative of v(t) and the derivative of a function f(x) evaluated at x=a gives the slope of the curve at f(a)

if light (or an acoustic wave) emitted in vacuum hits glass or water it changes its velovity. this provedure does not require time and a v-t graph for it would look like the a-t one i drawed above.
the slope of this graph at the time of contact is infinite so the acceleration is infinite (or goes toward infinite, whatever).

Apparently you're not. Why in the world would the slope be infinite? You're just not getting the simple fact that infinity is not a number, but a concept.

[Fluffz]

so what is it?

[DoTheFandango]

A concept of all the numbers can never end, and won't.


Also if you just smack the thing with a baseball bat as its excellerating, more than likely it will slow down.

No one ever heard of the Improbability Drive?

I love you, Nailed.

Nailed did you get that from HitchHikers Guide to the Galaxy? hmm...

What are you guys talking about? How to achieve FTL (Faster than Light) travel?

To answer your first question, No he got it from the most recent issue of Wired magazine.

to answer your second question, just read the damn thread.
