If I get a $1 (or a Euro) ..... If I get a $1 everytime someone asks or says one of these, I'd be able to fund the International Linear Collider all by myself (currently estimated at US$12 billion): 1. Since E = mc^2, and photons have energy, doesn't this mean that photons have mass? 2. Why doesn't an electron crash into the nucleus (or something to that effect)? 3. What do I see when I travel at the speed of light? 4. Evolution is just a "theory". 5. What is the BEST school for physics? I suppose it is expected that things get recycled since we get new members all the time. But sometime it feels as if we are making zero progress on any of these... <sigh> Zz.
