The Invisible Universe

Guest Speaker

Thursday, 7th December 2023 (19:45 - 22:00)

Venue: swmcmeet

The Invisible Universe refers to the vast and mysterious realms of the cosmos that cannot be observed through traditional optical telescopes. It encompasses a wide range of phenomena, including dark matter, dark energy, and various forms of electromagnetic radiation that lie outside the visible spectrum.

Dark matter, one of the key components of the Invisible Universe, is an elusive substance that does not interact with light or other forms of electromagnetic radiation. Its existence is inferred through its gravitational effects on visible matter, such as galaxies and galaxy clusters. Dark matter is thought to make up a significant portion of the total matter in the universe, shaping the large-scale structure of cosmic objects.
