Could our universe have more dimensions than the three of space and one of time that we experience?
Recent results from the Dark Energy Spectroscopic Instrument (DESI) have renewed interest in whether our current picture of the universe is complete. Some theories suggest that extra dimensions could help explain three of the greatest mysteries in physics: the nature of dark energy; the invisible influence of dark matter; and why gravity is so much weaker than the other fundamental forces.
From string theory to braneworlds, the search for extra dimensions pushes the boundaries of science and could reveal that the reality we experience isn’t all there is.
