In quantum mechanics,
the basic wave function has no physical meaning or significance. However,
represents the probability distribution of particle in a given space.
Probability
So when you will put a position and a time in
function, it will give you the probability of finding the particle at that particular position and at the given time.

Answer:</h2>
Dark matter is a type of matter, whose composition is unknown and which corresponds to 80% of the matter in the universe. Its name refers to the fact it does not emit or interact with any type of electromagnetic radiation, being completely transparent throughout the electromagnetic spectrum.
However, it interacts with the known matter through <u>gravity</u>.
In this sense, it is believed that the Milky Way has 90% dark matter and only 10% ordinary matter (known matter). Because, like gravity, dark matter can not be observed directly, however its existence is inferred through the movement of the stars and the cosmic dust within the galaxy.
