Invisible Universe
The Invisible Universe encompasses the vast, unseen components of the cosmos that dictate its structure, evolution, and expansion. At the core of this concept lies the mystery of dark matter and dark energy, which constitute the majority of the mass and energy content of the universe, yet remain largely undetectable by conventional means.
Dark Matter and Cosmic Mysteries
Dark matter is a hypothetical form of matter that interacts gravitationally but does not emit, absorb, or reflect light, making it “invisible.” Understanding its role is crucial to understanding the large-scale structure of the universe.
Alan Duffy’s Insights on Dark Matter
Key findings related to the nature of dark matter and the drive for discovery:
