breaking the speed of light article on howstuffworks.com

there are some really interesting articles on antimatter on nasa.gov

huh?

Ok, I gotta get off now, my mom sets a limit to how late I can stay on each day and it's 9:30 (I'm on ET). I'll check back in the morning.

You can choose your own métier(!), but don't be in too much of a hurry to decide. In any case, a meteorologist is a sort of physicist who alternates between bouts of depression and getting the wind up. (;-)

"Throw away your calculator..."

We were each issued a calculator, and we were supposed to finish the worksheet using the calculator. I finished, was bored, and graphed random equations - tan x^2 came out really odd... anyway, I don't own the graphing calculator so I can't throw it out. I see where you're coming from though. My point is that I wasn't intending to find out about the change in slope in a parabola; I was just amusing myself and happened to notice it.

As I said, I need to leave now, so that was my last reply

Probably. About 5 billion. We are halfway along the time-line. Is this a coincidence?

I should hope that after 5 billion years we won't still need cars. (;-)

There is bound to be evolution over such a long period, unless we are as stable in evolution terms as cyanobacteria.

Whaddya mean, start? It's been going on here for about two months.

Unfortunately for us, we naturally think in terms of linear cubic space (Euclidian space in three dimensions). No matter how much you think that way, it's impossible to visualise an absolute speed limit - so you're right there.

The speed limit actually does exist however, because space is curved and time dilates - the simple Euclidian model of space is wrong. "Space tells matter how to move, and matter tells space how to bend".

Hey, Jim, kids nowadays are amazingly sophisticated. By kid knew stuff when she was 10 that I didn't figure out til I was 40.

Ah, I wuz just wondering if you fell into the "wonders" of LSSD design.

Oh no! Enter Kevin to straigghten alll this out, again....

It's already warped.

Reverse time.

I never really studied subatomic particles, but just one thing I noticed, on your last question, you have the speed of light and speed of gamma rays as seperate answers. Gamma rays move at the speed of light, in fact they are light. Gamma rays are high-frequency EM rays. Matter-antimatter annihilation creates gamma rays, so the gamma ray answer to your last question may be more right.

You tell us. Who was saying otherwise?

Hint: dump google groups

We're all going to die anyway. If it's a three-cushion billiards shot or life, which do you take? Personally, I don't worry about things that are 5Bn years hence. My father had a perfect repsonse for those who said that the next ice age was coming "soon" (this was 20 years before "global warming" was all the rage); "Oh! I thought you said 500 years! You had me worried there for a minute."

If the alternative is...?

I think that's sorta the point...

Bad attitude. Do it right from the beginning and it's not all that painful. Ace the hell outta algebra and geometry and you're well on your way.

What they call "pre-calc" around here now we called "advanced algebra". Pre-calc is really about limit theory. If that's not in there it's not anything-calc. Study limits and geometry and calc won't be so bad.

More work! ;-)

So, you'e saying that photons striking an object don't impart any kenetic energy to that object? Conservation of energy and all here...

"Hey you! Where's my check!"

By George, I think I've got it!

I guess it's a good thing that TeeVees don't use relativistic voltages so they work just fine on planet Earth. I hate it when mine has a blue (state) shift.
