How big is نوترینو?
1 yoctometer!
نوترینوها همواره از مواد معمولی مانند من و شما عبور می کنند! در واقع، هم اکنون در حال انجام این کار هستند! نوترینوها بار ندارند، بنابراین تنها تحت تأثیر گرانش و نیروی ضعیف قرار می گیرند. گرچه، آنها آنقدر کوچکند که تأثیر پذیری بسیار اندکی دارند.
Planck Length
The planck length (lp) is a unit of length. There is also a Planck time, which is the amount of time it takes light to travel one Planck length in a vacuum. (Super short!)
Quantum Foam
According to the spacetime theory, quantum foam, which is also known as spacetime foam, is the foundation of the fabric of the universe. It is impossible to directly observe or measure this because it is so small.
String
According to string theory, strings are one-dimensional, but vibrate in all the other dimensions. This string, however, is not the same string that is used for flying kites. That string is between 10^32 and 10^33 times larger.
Bottom Quark
The bottom quark is also called the beauty quark, because it is so flawlessly beautiful. It is third generation and quickly decays into up and charm quarks.
Charm Quark
The charm quark and the strange quark are the second generation of matter. They will quickly decay into up and down quarks, which are the first generation of matter. The charm quark is charming.
Strange Quark
Strange quarks are very strange. They are 50 times as massive as up quarks, but are still smaller! Isn't that strange? Very much so! "Strange matter" is made up of up, down, and strange quarks!
