| Hello Cap: Nahh. The only thing that worries me, is the science that I was taught as a kid. I was told things that aren't true, and I was taught them as though they were. I was taught that the speed limit in the universe is the speed of light. I think that's as true as any statement is, before it's proven untrue. excon | ||||

| Oh yes, there are a number of phenomena that do propogate faster than light (and I'm surprised nobody has brought them up yet), but nothing that (as the OP asked) means "we" can travel faster than light. Taking "we" to mean humans on the macro scale. Dumbing down of science is one of the essential evils of science education, you just cannot comprehend the truth at that age without better mathematical knowledge. | ||||

| Hello again: I don't know if it had to do with dumbing down. I just think I was taught what they knew at the time, but that what they know changes pretty fast these days. Specifically, I'm speaking of plate tectonics. Of course, South America looks like it fits into Africa, but my teacher said it didn't. Whoa, ho ho on her. excon | ||||

| How about a ship powered by Hawking radiation, the only thing that can escape a Black Hole ? Even light can't do this ! | ||||

| Hawking radiation is produced from outsied the event horizon - light CAN escape from points outside the event horizon. Hawking radiation is just thermal radiation, but it's created by means other than black body spectra. Thermal radiation = photons = light. THerefore it moves at the speed of light. | ||||

Ok, what are they? Something to do with strings? Or things that happen in a particle accelerator? excon | ||||

I have a 3 speed Hunter ceiling that I rarely turn off and all 3 speeds had been working. I recently turned it off and when I turned it back on, only the high speed is working. I assumed the switch was bad and replaced it. I still only have the High speed. Has anyone had this problem before? ...
I installed this fan ok.....it was fine for 2.5 years now the remote only works the fan speed. It does not work the lights.
