Dark Matter & Dark Energy

In this engaging audiobook, Brian Clegg delves into the enigmatic realms of dark matter and dark energy, revealing that only 5 percent of the universe is made up of the visible matter we see, while the rest remains hidden. Since the 1970s, astronomers have grappled with the mystery of how galaxies hold together despite having insufficient visible mass, leading to the concept of dark matter. Clegg also discusses the acceleration of the universe's expansion caused by dark energy, a force that demands an energy equivalent to nearly fourteen times all visible material. This concise introduction offers insights into one of science's most profound puzzles and the ongoing efforts to unravel it.
