Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

Wow, I am suprised more people didn't take more of guess on this one.

How can you drop a dime from 4 inches above the table and have it reliably land on its edge?

Make it a very fat dime?
In case you're not allowed to do that, you can place a box on the table that is too narrow for the coin to be placed flat, and then drop the coin into the box.

Turn the table on it's side and drop the dime on the table's edge.
|
|
|
|
|
1) Leave it in the roll with the rest of the dimes.
2) Dip it in your beer and let it slide down the outside of your glass.

Let the dime roll off of your finger.

How about spin the dime as your are dropping it so it will continue to spin. It will be on an edge until it stops spinning. But it did 'land on an edge.'

Lots of creative answers for this one.
Hold it against a "sweaty" cocktail glass and let it go. It will slide right down the side of the glass.

That's not dropping ... that's "letting go"

If I'm driving down a dark road at the speed of light and I suddenly turn my
headlights on, will I see anything?

No, because you will have infinite mass, the gravitational pull you have on the objects around you will mean that what ever road you were driving on has been ripped out of the ground and is sticking your your infinitely massive body* , as will the ground the road was on, etc.
You will see nothing as even the light you emit will be unable to escape the now densly crushed headlights of the car.

So that's why my fingers get heavier after I've been typing for a while then. I've always wondered...

If you had a vehicle that could go the speed of light (impossible due to the whole approching infinante mass and time approching zero thing) you wouldn't see the light. The photon's would only keep up with you but not "shine" ahead of you.
So you wouldn't see the tree as you smash into it...at the speed of light...And that, kids, is what causes Nova's.

What happens to the photons that are being generated then? Do they sort of pool up at their source?

eh, stop bugging me about it, give it a couple of days, see what happens.

No, because you are going the speed of light, the light would not be able to shine from the headlights. Therefore it couldn't bounce of an object, and return to your eyes, creating an image you could see.

Regardless of an infinite mass (or even a zero mass), time itself is literally stopped for an object traveling at the speed of light. It is meaningless to "turn on" the headlights. You would not age even a moment to be aware of your circumstances, and you could perform no action in that "instant".

Huh? Now I nearly failed science but that sounds wrong to me. Time is local, not universal. The chap doing the speed of light wouldn't be in a timeless space. To those observing him and who aren't doing the speed of light then maybe it is instant.

t = t0 * sqrt ( 1 - (v^2 / c^2))
t is time period for traveler
t0 is time period for observer at rest
v is velocity of traveler
c is, well, speed of light
As you travel faster and faster, time flows slower and slower. *You* the traveler, wouldn't notice a clock on your spaceship ticking by any slower, but you would age slower than the people you left back on earth, and your clock would be behind the clocks you (pardon the pun) left behind. Plug in v = c, and all sense of time stops.
Of course, we have to be thankful it's not possible for v = c, for a variety of reasons.
Satisfied?
Cheers,
Vikram.

You will notice that that is what I stated. The whole relativity deal of observers. There is no timeless space. If you are doing the speed of light then your local area is not timeless. If you are sitting there at the intergalatic highway junction and someone goes past you at the speed of light your local space is not timeless either.
It is all relative to you.

(Vikram, hope you don't mind me reiterating the obvious)
As I understand the matter, we are speaking of the extreme: the question did not regard "approaching the speed of light" but "at the speed of light." As Vikram pointed out, time *is* zero (not *essentially* zero). When you speak of relativistic time, perception implies some movement of time (however slowly). If time stops, perception stops.
For example, if you were traveling very very fast, one second for the traveler (t) might be equivalent to a million million years to the stationary observer (t0); the traveler would not be able to *perceive* this slowing of time (i.e. time would be relative for him). However, *at* the speed of light, time has stopped for the traveler (t). He will *never* perceive the event to occur, nor will the stationary observer ever observe an event (unless the traveler should eventually slow to sub-light speed).
The flaw is in the question (apart from the obvious mass issues): one will/can never turn his headlights on while traveling at the speed of light.
