Why Do Particles Have Flavors?

” In this regular series, LiveScience explores some of the wildest, weirdest parts of our universe, from quantum oddities to hidden dimensions.

The building blocks of matter ? fundamental particles ? come in many more flavors than the basic few that make up the atoms we’re familiar with.

Flavor is the name scientists give to different versions of the same type of particle. For instance, quarks (which make up the protons and neutrons inside atoms) come in six flavors: up, down, top, bottom, strange and charm. Particles called leptons, a category that includes electrons, also come in six flavors, each with a different mass.

But physicists are baffled as to why flavors exist at all, and why each flavor has different characteristics. “

“Alien” Particles Found Invading Our Solar System?A First

NASA probe detects matter from interstellar space.

” For the first time, a NASA spacecraft has directly observed “alien” particles that came from beyond our solar system, astronomers announced today.

The discovery not only gives us a glimpse of what exists in the so-called interstellar medium?the matter between stars?but also offers clues to the anatomy of our local galactic neighborhood.

Orbiting Earth some 200,000 miles (322,000 kilometers) away, the Interstellar Boundary Explorer (IBEX) spacecraft was able to snag samples of hydrogen, oxygen, and neon that came from interstellar space.

“It’s exciting to be able to have these first observations of alien matter?stuff that didn’t come from our sun or the planets, but came from the outside of our solar system, from other parts of the galaxy,” David McComas, team leader for the IBEX program, said during a NASA news conference Tuesday.

“We think these are really important measurements, because these elements are the fundamental building blocks of stars, planets, and people.” “
