Is there any scientific findings that proves what is next,after death?

I very often wonder that the moment a man expired the material body ends up stationary and then gradually freeze. But,what would in fact happen to the "SOUL" as soon as man died off? and to which extent it is true that the soul is immortal which would take form into different one and reborn to the world again? Does it really hold water that the deceased would always stay with their loved ones even if the body are cremated? If it can be true, Is there any scientific testament that proves what is next,after death? Do we have that material that could possibly trail the "Soul"?
