Today, according to NASA's satellite estimates it [the universe] consists of the following: Dark Energy 72%, Dark Matter 23%, the matter we know, including light, 4.6%. The total does not add up to 100% because there are always some uncertainties in the numbers obtained. Everything you've seen so far throughout your journeys correspondes to only 4.6% of the total content of our universe. The rest...is unknown.

Our image is here and will for ever stay,and there is comfort in knowing that the memory of our lives will always be there,traveling among the stars.

A clock that is moving through space at a very fast speed does not tick at the same rate as a slow-moving watch gently attached to your wrist as you stroll on a tropical beach. The idea of a universal time - a godlike clock that could somehow sit outside our universe and measure, in one go, the movement of everything in it, how its evolution unfolds, how old it is and all that - does not exist.

Mankind has uncovered two extremely efficient theories: one that describes our universe's structure (Einstein's gravity: the theory of general relativity), and one that describes everything our universe contains (quantum field theory), and these two theories won't talk to each other.
