A team of scientists headed by Adam Riess, a professor of physics and astronomy at Johns Hopkins University in Baltimore, said in a NASA release that they have new evidence which reinforce the idea that the Universe you and I live in, is expanding.
"Riess's work gives new evidence that the universe is in fact expanding at an increasing rate because it is filled with a dark energy that works in opposition to gravity. Dark energy is a type of energy that astronomers believe permeates all space."
