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.

Thats done it.
now i need to look for a site that explains why the earth is flat:D

Thanks for the link..... :rotflmao:

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?:confused:
And if you are traveling faster than the speed of sound and you blow your horn, does it make a noise you can hear?:confused:
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.:cool:

you could use it to read with :D

If your ship/car is traveling at the speed of light and you turn on your headlights, will the beam of light actually show?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 (http://en.wikipedia.org/wiki/Speed_of_light#Constant_velocity_from_all_referenc e_frames).
And if you are traveling faster than the speed of sound and you blow your horn, does it make a noise you can hear?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.
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.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. :)

I will wait until monty python's a brief history of time is released. :D

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

[Snurfen]

"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).

[Nick Grana]

I know you are not referring to me, dude. I'm never boring.:D
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. (http://answers.yahoo.com/question/index?qid=1006051708761):thrilled:

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.

[black mirror]

Does the missing odd socks theory fit into this thread i wonder?

No, I haven't ;) It's like, "If a tree falls in the forest and there is no one ther to listen - who cares" :rotflmao: (like the line of enquiry there jer, come up with some others of that vien) hard not to say "train of thought" or "along that track" there - would've got punned to death if I had.

Does the missing odd socks theory fit into this thread i wonder? No, didn't Douglas Admas write about the planet where all the odd socks teleport themselves to?

[Vercades]

Lol @ Snurfen.

That question is actually on most tests in college varies from time to time to keep cheaters from cheating.
