Nothing lasts forever. One can't even depend on atoms lasting forever or the particles they're made of. Space, time energy and momentum aren't "things" so I'm not counting them.

Protons are reputed to have a life of at least 10^33 years but there has been no experimental confirmation

if nothing last forever, where matter and energy go at last?

empty void? does it last forever?

we are talking about time, is time has beginning or ending?

when time ends, what time is it?

If protons never decayed then it still wouldn't mean that they last forever. When they collide with a cosmic ray they undergo particle interactions which destroy the proton and result in new particles. That's why I didn't say that particles that don't decay last forever. There's always a method to my madness. :)
