The universe began with the Big Bang, and is estimated to be approximately 13.7 billion years old (plus or minus 130 million years). Astronomers calculated this figure by measuring the composition of matter and energy density in the universe, which enabled them to determine how fast the universe expanded in the past. As a result, researchers could turn back the hands of time and pinpoint when the Big Bang occurred. The time in between that explosion and now makes up the age of the universe.In the 1920s, astronomer Edwin Hubble made the revolutionary discovery that the universe is not static, but rather is expanding. But, it was long thought that the gravity of matter in the universe would slow this expansion or even cause it to contract.
In 1998, the Hubble Space Telescope studied very distant supernovas and found that, a long time ago, the universe was expanding more slowly than it is today. This puzzling discovery suggested that an inexplicable force, called dark energy, is driving the accelerating expansion of the universe.
Mysterious dark energy is not only thought to be driving the expansion of the universe, it appears to be pulling the cosmos apart at ever-increasing speeds. In 1998, two teams of astronomers announced that not only is the universe expanding, but it is accelerating as well. According to the researchers, the farther a galaxy is from Earth, the faster it is moving away.
The universe's acceleration also confirms Albert Einstein's theory of general relativity, and lately, scientists have revived Einstein's cosmological constant to explain the strange dark energy that seems to be counteracting gravity and causing the universe to expand at an accelerating pace.
