LISA Pathfinder satellite to test method to find ripples in space

An experimental satellite scheduled for launch in the early hours of this morning will test a technique to detect ripples in space and across time, adding a new perspective for viewing and understanding the universe.

From a vantage point 93 million miles (1.5 million km) from Earth, the European-built spacecraft, known as LISA Pathfinder, is expected to break ground in the search for the ripples, known as gravitational waves, caused by fast-moving, massive celestial objects such as merging black holes.

Black holes are so dense with matter that not even photons of light can escape the powerful gravitational effects.
