That's ok, I tend to believe things when other people know what they're talking about and I have less of an understanding. My world view isn't shaped entirely by that, but when I don't understand it I tend to be more likely to believe others. I'm sorry if I upset anyone, that wasn't my intention.

But zhermes said: I didn't make the original claim, I was basing my question off of a claim made by another user.

Thanks, zhermes. I just always assumed that a physical body with volume had to contain mass, otherwise it wouldn't be considered a physical body but a lack thereof. I see my error now. But I have one more question, since we always saw electrons as points until recently, wouldn't the same...

What I have been taught in high school physics says that all particles can be interpreted as waves, and all waves as particles. By definition, particles have volume, and therefore must have mass (in a physical sense). Photons are always regarded as waves, but therefore could always be...

Ok, this is making a bit of sense now. Thanks, guys,

Right, and that's what I used. The answer to my original question came out to be something that seems more realistic, but I still don't understand why they aren't just added. Say a car, driving at a constant speed of exactly thirty MPH, passes a jogger running at exactly five MPH, in the...

Care to explain what I've done wrong? Simply saying that I've done something wrong without explaining what's wrong doesn't help too much, seeing as how I plugged in numerous values in several different orders. EDIT: I plugged in the value -0.99999 for vB, and it gave me a more reliable answer...

But if I were to substitute in the velocities of both particles (relative to a stationary object), then wouldn't their velocity (relative to each other), if they were moving at equal speeds, always equal zero, or did I plug something in wrong? I plugged in 0.9999999 for both vA and vB. EDIT...

This concept may have been discussed before, but I couldn't really find any that asked the same question. Through multiple sources, I have discovered that, in the LHC, we have the ability to propel protons to 99.99999% the speed of light (relative to a stationary object), and make them collide...
