String Theory

Don't understand string,no matter its so easy.String
theory attempts to unite quantum mechanics and general
relativity,so we can make sense of the universe on all
scales, at any place or time, large or small without
breaking down.
String theory does this by throwing away the idea that
subatomic particles are point-like; instead replacing that
notion with tiny vibrating bits of energy, called strings.
They’re so tiny that if you think a single atom to the size
of our solar system, a string only be the size of a tree on
earth.
These stricg are said to vibrate at different rates. These
notes or vibrational friquencies are what give rise to the
different properties of quarks and atoms.
One particular type of vibration may give rise to a muon,
while another represents an electron. By changing the
vibration of the strings, you can create different
particles.so who said that we can not make anything?so
go ahead,we can do this.can we?
