doesn't it just burn you up? [Jan. 27th, 2004|11:56 pm]

sometimes, i get caught in an endless loop. Like, when I ponder relativity. I cannot seem to escape the paradox of knowing that energy and matter are interchangeable, and light has energy, and light can travel at light-speed, yet matter cannot. Why does light have no mass?

Or how about this one, that light can act as a particle (mass) as well as energy - yet it still moves at the speed of light.

And of that particle/energy thing - if you split a beam of light and use one segment to act as energy and the other as a particle - it will only act as one /or/ the other depending on which test it gets to first for the WHOLE beam (ie back through the splitter and to the other test!).

Boggling. There's a piece of the puzzle we're missing on light and light speed :]

on the whole

i can accept the dual-nature particle-wave thing. i just have trouble with the transition between the two.

where I don't follow you

mass does not always have half-integer spin, iirc. There is bosonic (integer) and fermionic (half integer) mass.
