Bob Vosatka science educator at the Liberty Science Center, talks about the breakthroughs that won this week's Nobel Prizes in medicine, physics, and chemistry.
To the caller's question about moving faster than the speed of light:
As explained in my university physics classes, Einstein postulated that light travels at the same speed regardless of the speed of the observer, and light has a maximum speed limit. He also said you cannot accelerate matter to or past the speed of light.
However, neutrinos are not accelerated past the speed of light, per se, if they are always traveling faster than that limit. There's no acceleration going on. Also, the expansion of the universe is not just objects moving apart. If they were, they would be limited by the speed of light. Actually, it's space itself that is expanding. Objects are driven apart by the growth of the space between them. A galaxy would not accelerate to a speed greater than the speed of light, but the space between two galaxies has no such limit.
Is there any scientific principal to explain why so many Nobel prizes are won by folks of Jewish ancestry? As a Jew myself, I am proud! But also, mystified by this...
