Light is so fast it goes backwards.

Strange, discovery? Or, just over hyped scientific experiment?

If, you want to confuse yourself alot, go ahead and read it.

Very interesting.
I guess all have heard this scenario:
If your ship/car is traveling at the speed of light and you turn on your headlights, will the beam of light actually show?
And if you are traveling faster than the speed of sound and you blow your horn, does it make a noise you can hear?
I guess it all has to do with relativity. If you are on the ground and see a jet plane, the higher up it is, the slower is appears to be moving. Now the people on the plane have no feeling of moving at all unless they look out the windows. And while you are flying at 500 MPH and you drop a book, does it fall straight down to the floor or does the speed of the plane have any influences of where the book lands.
Crazy enough for you? Ok. Absorb that for a while and don't stress.

Yes, because it's travelling at the speed of light (relative to the car). Assuming that a vehicle can travel at the speed of light with no ill effects, which it can't. And light itself cannot travel faster than the speed of light. See here.

If the horn emitter is in front of you (as it is in most cars), then yes, you will. With a sound source behind you, you'll be moving too fast for the sound to catch up. There will also of course be a sonic boom.

Both the plane and the book are moving forward at 500MPH. The book, once release, has no horizontal wind resistance (since the air inside the plane is also moving at 500MPH), so it falls straight down.

I was going to answer the questions, but oracle128 beat me to it. Good explanations & link.

I suggest reading A Brief History of Time by Stephen Hawking. It's a very good introduction to physics (mostly theoretical and astrophysics). If you've already read it, read it again.
Edit: online version here.

If you're going to be bored, don't visit the blatant science-related thread...

"blatant science".... the worst kind.

Stephen Hawkings did the undoable for me - made Physics sound boring. This particular book of his is the most boring scientific (pseudo ?) tome I have ever cast an eye between the covers of.
It did for physics for me what the DaVinci Code drivel did for thrillers.

It's also (by Hawkings own admission) a bit off the mark in several areas.


Ora, I was not saying science is boring, or the topic was boring, just that two of the threads before mine were exceedingly so!

(Runs and puts flameproof vest on).

I know you are not referring to me, dude. I'm never boring.
All my Q's were for fun only but it's not as corny as it appears.
A lot of people wonder the same thing as HERE.

Anyone ever thought if you put a pendulum on a train and, while it goes backwards and forwards, is it going faster and slower then the train at the same time?

Hint: Gravity has a lot to do with this one.
