  • Dunno if Schroedinger ever owned a cat. But he was a renowned womanizer so he got a lot of pussy.

  • How were the universal forces initiated and what caused the formation of the primary subatomic particles?

  • @farshad94abedi photons have no mass

  • @kiemul136 Well, they have in the last 10 years discovered two elements, so... maybe there's more out there, if not they're infinite.

  • When you see sped up video of a galaxy spinning...why do all the stars spin at the same rate regardless of there distance from the center? Shouldn't the outer stars be orbiting the center at a slower rate? Related to that...if all the stars are spinning at the same rate, how far out does that extend? The rotation of space that is.

  • @lolmomz No, all the elements have been accounted for.

  • @TheAceMcGirk One is a wave made from a photon(light) the other is a wave of atoms(sound). Completely different. The doppler effect isn't a mechanism to lower or speed up the frequency of sound or light, it is the byproduct of doing so.

  • considering light can be a particle, and that a partice can be a light (wave), what is the radius of a photon, and also, what is the radius of an electron?

    furhtermore, if light can have a physical characteristic, then using e=mc^2 to find the equivalent mass, is there a possability that light may have gravitational characteristics as well?

  • Is there an infinite number of elements?

  • @Backo119 wtf kind of question is this? Wormholes have only been hypothesised and we have no way of doing an experiment like this...

  • Can light be lengthend down to sound and/or vice versa via the doppler effect?

  • @Backo119 that happened to me yesterday, i shat myself
