From the Ted Talk by Brian Greene: Is our universe the only universe?

Unscramble the Blue Letters

Okay, part one starts back in 1929 when the great astronomer Edwin hbbule realized that the distant galaxies were all rushing away from us, establishing that space itself is sihctntreg, it's expanding. Now this was revolutionary. The prevailing wisdom was that on the largest of saelcs the universe was static. But even so, there was one thing that everyone was certain of: The expansion must be slonwig down. That, much as the gravitational pull of the Earth slows the ascent of an aplpe tossed uwrapd, the gravitational pull of each galaxy on every other must be slowing the expansion of space.

Original Text

Okay, part one starts back in 1929 when the great astronomer Edwin Hubble realized that the distant galaxies were all rushing away from us, establishing that space itself is stretching, it's expanding. Now this was revolutionary. The prevailing wisdom was that on the largest of scales the universe was static. But even so, there was one thing that everyone was certain of: The expansion must be slowing down. That, much as the gravitational pull of the Earth slows the ascent of an apple tossed upward, the gravitational pull of each galaxy on every other must be slowing the expansion of space.
