Suppose an antimatter at lower energy(K.E) collides with a matter in higher energy then what will be the output.

Can antimatter(positron) can be converted into a matter(electron) . If yes what other particles are created in that reaction

In many websites I read that antimatter has antigravity properties. Does negative mass exist. Does antimatter react differently with gravity.

”According to the general theory of relativity space without ether is unthinkable; for in such space there not only wonld be no propagation of light, but also no possibility of existence for standards of space and time“...this in an statement given by einstein...please tell me what is the ether...

Recently I read that gravitation and electromagnetism is unified by Kaluza-Klein theory. Can someone tell me in depth how they are unified

What are the differences between matter and antimatter. I know they have same spin, same mass and opposite charge. Does there are any other minute differences? Please mention.

Why the early universe started expanding

As matter & antimatter are equally created in the early universe , then why matter dominated over antimatter. Please suggest any possible answer

As mass increases with increasing velocity(energy) and gravity is directly related to mass . Does gravity of a body increases with increasing energy
