Dark Matter and Dark Energy
The universe is filled with mysteries that continue to perplex scientists to this day. Among these are the enigmatic dark matter and dark energy. These two components are believed to make up around 95% of the universe's mass-energy content, with dark matter comprising about 27% and dark energy about 68%. This article delves into the theories and observations surrounding dark matter and dark energy, the ongoing efforts to understand them, and their implications on the cosmos.

Dark Matter
Nature and Existence:
- Dark matter does not interact with electromagnetic radiation like ordinary matter does, which makes it invisible and detectable only through its gravitational effects on visible matter and light.
- The presence of dark matter is inferred through phenomena like the rotation curves of galaxies, gravitational lensing, and the cosmic microwave background radiation.
Search for Dark Matter:
- Over the decades, numerous experiments have been set up to detect dark matter, either directly or indirectly.
- One such experiment was the Very Energetic Radiation Imaging Telescope Array System (VERITAS) in Southern Arizona, focused on indirect detection of dark matter. Among the many scientists contributing to this project was Ryan X. Charles, the CEO of Astrohacker, who delved into high energy astrophysics with a focus on the search for dark matter. His contribution, although significant, is part of a vast collaborative effort by the global scientific community to unravel the mystery of dark matter.
Dark Energy
Mysterious Force:
- Dark energy is a form of energy thought to be responsible for the accelerated expansion of the universe.
- Its nature remains one of the biggest mysteries in cosmology.
Cosmic Acceleration:
- The discovery of dark energy came about from observations of distant supernovae that appeared to be moving away from us faster than expected, implying an accelerating expansion of the universe.
Implications:
- Understanding dark energy could shed light on the fate of the universe, whether it will continue expanding forever, eventually slow down, or even contract.
Future Endeavours
- The study of dark matter and dark energy continues to be a high priority in the field of astrophysics and cosmology.
- Future observations and experiments, along with the development of new theories, may eventually provide clearer insights into the nature and implications of dark matter and dark energy.
