Dark energy is a mysterious force driving the accelerated expansion of the universe.
The universe has been expanding since the Big Bang, but its acceleration was an unexpected discovery.
Dark energy seems to counteract gravity, pushing galaxies apart faster over time.
In 1998, astronomers found that the universe’s expansion is accelerating, pointing to the existence of dark energy.
Dark energy makes up around 68% of the universe’s total energy, but its nature remains a mystery.
Some theories suggest dark energy might be a property of space itself, while others propose a new force of nature.
If dark energy continues to dominate, the universe could end in a “Big Freeze,” where galaxies drift apart indefinitely.
Scientists are using space telescopes and surveys of distant galaxies to learn more about dark energy.
Some theories suggest that dark energy might modify gravity on large cosmic scales.
Unraveling the nature of dark energy could reshape our understanding of the universe’s fate.
