What is Time?

Atom Isn't mass the amount of stuff that thing is made of?

Space-time is the dimensions our universe exists in. (X, Y, Z and time.)

Gravity is a force that things with mass 'create'. Gravity pulls things towards it's source. It is theorised that it is caused by a curvature of space-time.

In conclusion, I think we do know what those 3 things are...though we might be wrong.

No Lad! "Mass" only implies what we see. Density is what stuff is really made of. Your statement: Space-time is the dimensions our universe exists in. (X, Y, Z and time.) is about as stale a day old can of opened beer.

Your statement: [Quote] Gravity is a force that things with mass 'create'. Gravity pulls things towards it's source. It is theorised that it is caused by a curvature of space-time.

And "Theorized?" What in heck is the validity of "THEORIZED?"? 90 % of our sciences are THEORIZED. 10% actuall brings you healing medicines and hopeful cures for other illnesses. The understandable physics of our past twenty generations studying the universe has created nothing more than conjecture. Get a leg up kid and study medicine. Either that, or find us an express trip to Andromeda.

And using "MASS" as you did? I would not embarass your parents.
