  • Can somebody answer me this please?

    Why doesnt the gluon, photon and graviton interact with the higgs field yet the W and Z bosons do?

    Please try and get back to me.

    Thanks.

  • while the photon theoretically doesn't interact with the Higgs field, the gluon, which might have a very slight mass of a few MeV/c^2, does. As a result of it's very tiny mass, it's short range (similar to the w and z bosons) and is confined to the nucleus. Mean while, the photon has no mass and infinite range.

  • steve, you are a fucking science warrior. thanks for all the incredible videos!!

  • I believe that simply by expecting to find a smaller particle, or by expecting to find more galaxies, we are literally creating our own universe...anybody dig?

  • I could answer you, but I'm busy packing for Stockholm.

  • Whoops! O2H. He he he!

  • awesome

  • I think this is old. A bit confusing also, considering the water molecules are incorrectly depicted.

  • Those water molecules look like horrified faces. Understandable, since water isn't O2H...

  • ho2 ;> ???

  • Some maniac just sucked up the letter D off my keyboard with his vacuum cleaner and I shear to God the key vanished from the face of the earth!! Quantum field that!

  • You are correct. Very silly oversight by the speaker.

  • careful, not all that is called a particle is a real full particle. Check the life time those "particles" have and you will find the electron as a basic particle and others are more like fragments (parts of particles).

  • i checked wikipedia and it says that water contains of 2 Hydrogens and only one Oxygen... hm?
