What is the true nature of dark matter and dark energy?
Dark matter and energy are two of the biggest mysteries in the universe. Dark matter is like an invisible glue holding galaxies together. We can't see it directly because it doesn't emit, absorb, or reflect light. However, we know it's there because of its gravitational effects. When we observe galaRead more
Dark matter and energy are two of the biggest mysteries in the universe.
Dark matter is like an invisible glue holding galaxies together. We can’t see it directly because it doesn’t emit, absorb, or reflect light. However, we know it’s there because of its gravitational effects. When we observe galaxies, they spin faster than expected based on the visible matter. This suggests there’s something extra, something we can’t see, adding to their mass—this is dark matter. It makes up about 27% of the universe.
On the other hand, dark energy is an even more puzzling force. It’s not matter at all, but rather a kind of energy that seems to be pushing the universe apart, making it expand faster and faster. Discovered in the 1990s, dark energy accounts for about 68% of the universe. This discovery was shocking because it suggests that the universe isn’t just expanding, but it’s doing so at an accelerating pace.
Together, dark matter and dark energy make up 95% of the universe, yet we still know very little about them. their true nature remains one of the most profound questions in modern physics. Scientists are continuously searching for answers through experiments and observations.
