Ok, I don't want no equations and stuff please. :smile:
When light travels through a medium the photons are absorbed by atoms in the medium and then a photon is given off by the atom of similiar energy, etc, this is correct?
If this is so does that mean when I look out the window that I'm...
I told him to get a particle with mass to the speed of light you'd need infinite energy and that would cost you. :rofl:
I don't know how to calculate anything with this stuff. I just read this stuff for fun. :eek:
One of my friends told me that photons would have to have mass or they couldn't exist. I told him that if they did have mass a photon would knock you on your arse and turning on a light would cost you a fortune when your power bill arrived.
Kip Thorne and Hawkings have a bet on travelling back in time.
What's that conjecture......... um........ the Time Protection Conjecture or something. Basically any time machine would destroy itself the instant you tried to use it to travel back in time. Something like that.
All particles with a rest mass greater than 0 travel at below the speed of light.
Particles with 0 rest mass only travel at light speed.
Particles with less than 0 rest mass should, if they exist, travel at only greater than light speed.
I remember reading a while ago that the fabric of space has a texture and thus would cause friction. Even in a perfect vacum a spacecraft would slow down over time due to this.
Is this an accepted theory?
Many parts of the ocean floor are covered in methane "sludge."
These can break off and rise to the surface in huge bubbles. If a ship is partly in the bubble and partly out it will sink. If it's a large ship it will break in 2 and sink.
I saw one documentary on how to solve Flight...
You need to bone up on your history.
The US warned the Japanese that they had a new weapon capable of destroying a city. The Japanese didn't care because they were going to fight until the last Japanese died taking an Allied soldier with them.
Both Hiroshima and Nagaskai were industrial...
I've had the chance to observe Omega Centauri through a, 24inch I believe it was. I was awe inspiring. Also saw many other objects but of course, for me that is the one that stood out in my memory the most.
I haven't gotten my scope out much in the last few years, but when I did (it's a...
So your average GPS sat. is going at a relativistic speed because if you didn't take time dilation into account they'd give you the wrong position? But for the rest of us who cares that our car is going 60kph?
I think I remember reading about some experiment where they had a tank underground (so there was no light) full of water or something. The tank was big enough so that a few protons a year should decay. They set up some very senistive cameras to detect the flashes of light that would be given...
