The universe has been expanding since the Big Bang — but can we actually see it happening in real time? Scientists have discovered that galaxies are moving away from us, and the expansion is even accelerating due to mysterious dark energy. Some galaxies are receding faster than light itself, changing our understanding of space, time, and the future of the cosmos. Observations from powerful telescopes like the James Webb Space Telescope help scientists measure this expansion and reveal how the universe evolved over 13.8 billion years. This discovery shows that the universe is alive, dynamic, and constantly changing.
