Dark matter experiment finds no evidence of axions. Physicists have performed the first run of a new experiment to detect axions -- hypothetical particles that are predicted to be among the lightest particles in the universe. The team reports that in the first month of observations, the experiment detected no sign of axions within the mass range of 0.31 to 8.3 nanoelectronvolts. This means that axions within this mass range either don't exist or they have an even smaller effect on electricity and magnetism than previously thought. Source 2p.
I've heard the theory about dark matter's existence along with dark energy. It's supposed to not really affect humanity but change how the universe operates today. Could it be that even if no Axions are detected there might be other particles lighter or smaller that are unable to be seen so far?
