I have heard many times in news that a new discovery has taken place, and we need a new physics.
It has recently been announced in scientific news that the world is apparently expanding faster.
And guess what? Everyone says we need a new physics! I'm also interested in having a new physics, but we did not have a new physics in the past 100 years!.
Anyway, what does it mean that the universe is expanding so fast and we need a new physics?
Do we have such things as new physics or old one?
Do we really need a new physics (whatever the circumstance)?
