Where does sound, light or energy stop?

***All trapped by the gravitational field. Or if you prefer the context of Einstein's General Relativity where gravity is expressed as the dynamics of spacetime, light cannot escape the event horizon becasue space there is being sucked in as fast as the speed of light***

Where is the finite universe in a constant state of constant change.

***Outside the black hole***

Have we and can we measure its mass?

***Yes, from the motion of stars it its vicinity***

Or do we put finite's to an infinite universe?

***We can only see a finite part of the universe. Who knows if it is infinite or not?***

Does anyone really know what time it is?

***Fundamentalist Orthadox Jews and Christian think that it is about 6,000 years. Astronomers think it is 14 billion years. String and loop physicists think it is forever***

I think that's a song.

***Amen***
