Scientists conclude that the universe may expand forever


A study of the amount of dark matter in the universe suggests that the universe itself may continue to expand indefinitely. The projected future does have its drawbacks, however; 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 researches used data from the 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.

Researchers predict that when the point comes when it is a cold, dead expanse, the temperature will approach what scientists call ‘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”.
