A study of the amount of dark matter in the universe suggests that the universe itself may continue to expand indefinitely. Researchers say that the universe will likely then become a cold, dead cosmic wasteland. The study was conducted by an international team of researchers led by Professor Eric Jullo at NASA's Jet Propulsion Laboratory in California. The researchers used data from the Hubble Space Telescope showing the way that light was distorted, known as a gravitational lens, from a large galactic cluster known as Abell 1689 to estimate
A study of the amount of dark matter in the universe suggests that the universe itself may continue to expand indefinitely. Researchers say that the universe will likely then become a cold, dead cosmic wasteland.
The study was conducted by an international team of researchers led by Professor Eric Jullo at NASA's Jet Propulsion Laboratory in California. The researchers used data from the Hubble Space Telescope showing the way that light was distorted, known as a gravitational lens, from a large galactic cluster known as Abell 1689 to estimate the amount of dark energy to be about three quarters of the universe.
Dark energy is a completely invisible force that is constantly acting upon the universe. Its existence is known only because of its effects on the expansion of the universe.
As the universe expands and cools, the temperature will approach absolute zero.
Jullo says that scientists can now say, for the first time, that the universe "will continue to accelerate and the universe will expand forever".
