The Scale of the Universe. Light travels at 300,000 kilometres per second (186,000 miles per second).

The Scale of the Universe

In one second, a beam of light can travel SEVEN TIMES around the Earth. This table shows a number of distances to various objects expressed in terms of how long a beam of light takes to travel that distance. Time scales longer than the age of the Universe are possible because of the expansion of the Universe.

The scale of the Universe and our place in it are well summarised in Monty Python's Galaxy Song. © 1997, 2013 KryssTal You can try out our Testking 220-701 certification material and latest 642-427 dumps to get high flying success in testking 642-262 certification exams, beside testking 77-605 exam product for certifications like testking 70-541 are also very useful tools.

This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything. " Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest.
