Unveiling the Mysteries of Dark Matter, Dark Energy, and Antimatter (Part II)
In our previous article , we discussed the nature of dark matter and now we'll continue with dark energy and antimatter. Dark Energy Image from: NASA Science Dark energy makes up around 68% of the universe , but even less is known about dark energy than dark matter. What we do know is that dark energy is the mechanism behind the acceleration of the universe’s expansion. Detection of Dark Energy So, how was dark energy detected? Observations of distant supernovae showed that the universe expanded more slowly in the past than it does now. The main explanation is that the universe contains something that reverses the gravitational effect where the universe is pushed apart faster and faster instead of being pulled closer to itself - which is dark energy. Cosmological Redshift As the universe expands, the light traveling to Earth from these far-away galaxies and supernovae gets stretched to longer wavelengths which is called cosmological redshift.
