What makes the molecule that's being aimed/shot at (the tire) so special? Why do the arrows only push what's *between* the shooters and the tire (Joe) and not the tire itself? Now consider another guy, Jack, walking into the path of the arrows right *behind* the tire where they've just left it. Shouldn't he be pushed *away* from the tire?? A.

Seriously - is this what they mean by expansion of space!!?? A.

Hi everyone. Why is it acceptable to talk of the frequency of a photon - a massless particle traveling at the speed f light? What does it really mean? Thanks. A.

Hi. What does it mean when one says "fundamental forces are 'carried' by particles" or "certain particles 'carry' fundamental forces"? Consider the proton and the "orbiting" electron in a Hydrogen atom. Are these two constantly emitting particles that carry electro-magnetic attraction? And since it seems impossible for either to truly continuously emit the force-carriers, is the attraction intermittent? Can either ever exhaust its supply of these force-carriers? As you can tell, there are many aspects of this concept I find baffling! :) I will be truly grateful for a clear explanation :hyper: Thanks. A, Restless.

The Q&A forum is tempting me to unload quite a few questions. :shrug: I wonder if it's considered proper form to ask without first checking if they have been answered elsewhere on the web (not necessarily on Hypography. Suppose I haven't found any yet or haven't been satisfied with what I found? (no specific examples) Thanks. A.

Excellent advice for an archer!! :doh: Thank you. And, yes, PBS is still popular with me I like the way you play with words :) A ->O

Well, ...I suppose ratings are important :shrug: More and more new shows have real scientists acting as anchors and I think they overcompensate when they try to sound "hip" and avoid looking like the popular stereotype for a scientist And maybe its counter-productive - I'm looking for Science in a science show and not drama, right? A.

Thank you pamela Us archers aren't supposed to be depressed, you know :shrug: A.

I like it!

Hi everyone! Found myself wondering if makers of science shows on TV think that earnest talk about science *must* be boring, so, "spice it up" or that those who watch them are all dense (or may be they *know* so - why else would one watch science shows, right?) or that nobody pays attention so "Keep It *Simple*, Stupid!"... Anyway, got tired of trying to stumble upon knowledge on TV ::shrug: Found an old bookmark I'd made to this site. Don't remember why I didn't check back after the first few visits, but I think I'll stick around this time :) I'd very much like to understand what they mean when they say, with all the requisite awe, that "even light can't escape!" or "space itself is expanding!" or "space might be curved!" or "there just isn't enough matter!!" and so on. I see there's a lot to read here already - First of all, I'll try to find what you folks have said or dug up on the expansion of the universe! :-) I'd also like to gather up enough nerve to go take a refresher course in high-school Maths and Physics someday and probably go on to study Physics... some day! I am a programmer. I live in Frederick, Maryland (USA) - would like to live in Arizona or Colorado or some such place. I'm a Sagittarius and am sooo depressed!! :D See you around! A.
