ccjbssxx asked:

Hello there, I was just wondering if you could summarize the fundamentals of a quark. I've read about them, but I'm kinda fuzzy on their whole purpose & concept. Thank you much! :)

the-actual-universe answered:

Here is a post that discusses the fundamental particles, including quarks, but I’ll do some quick bullet points for you as well. 

  • Quarks and leptons are the basic building blocks of matter (There are antiquarks and antileptons as well, but we’ll get to that later).
  • Quarks combine to form particles known as mesons (a quark and an antiquark) and baryons (three quarks). Baryons include protons and neutrons.
  • There are six types (called “flavors”) of quark: Up, Down, Charm, Strange, Top, and Bottom. Each flavor has a different charge. Only up and down quarks have been observed in nature; the rest have only been made in particle accelerators.
  • Every flavor of quark has a corresponding “antiquark” which has the opposite charge (So, an up quark will have a charge of +2/3 while a down quark will have a charge of -2/3).
  • Protons and neutrons are only made of up and down quarks. A proton has 2 up and 1 down, while a neutron has 1 up and 2 down.
  • These up and down quarks are held together by gluons, which are particles that carry the strong force.
  • Mesons, as I mentioned earlier, are composed of a quark and an antiquark. Because they are composed of a quark and its antimatter component, they exist only momentarily and destroy themselves rather quickly. Their decay leaves behind only energy.

Hopefully that helped break things down…there’s a lot more but this could get very long and tiresome to read if I tried to include everything! 

Oh, thank you so much! I’m not sure if you’re a teacher, but you definitely could be a great one!

Second Solar System Detected
A team of astrophysicists at the German Aerospace Center (Deutsches Zentrum für Luft und- Raumfahrt; DLR), together with German and European colleagues, has discovered the most extensive planetary system to date. Seven planets circle the star KOI-351 – more than in other known planetary systems.
They are arranged in a similar fashion to the eight planets in the Solar System, with small rocky planets close to the parent star and gas giant planets at greater distances. Although the planetary system around KOI-351 is packed together more tightly, it provides an interesting comparison to our cosmic home.
