What is time??

WHAT IS TIME????

so it is a very complicated topic for us.. in classical physics time works as relativity .it is directly depend on distance and inversely proportional to the mass of object.if a tennis ball move in 5 meter length it takes few seconds now again do this action but replace the tennis ball by foot ball then you take the different results so that change was possible bye the mass of tennis and foot ball. 

but in Quantum mechanics this operation will be fail because there is no humans sense actually human observes time by its three dimension world but our universe is based on 10 dimensions so no clearly learn what is time with the help of quantum mechanics

 

so, it look as wave function the classical physics is us 

and the quantum tunnel is space time the actual time of our universe so the knowledge of quantum mechanics just help us in the space time where is highest or lowest chance of presence of us 

If you want to know about time deeply, so check this book about time: The Book Of Time

After read this you have no doubts about time.

Thanks for reading!
