Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new ...

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level.

Arkani-Hamed believes the concept of time itself may be behind the discrepancy. In physics equations, time is used to keep track of the sequence of things as events unfold.

The question of the beginning of time must therefore be addressed within a theory of quantum gravity. Sandro Gianella, Head of EMEA Policy & Partnerships, on stage at TNW Conference 2025 ...

If the laws of physics are not time-reversal invariant, the different decays in a specific order will exhibit different properties. This was confirmed in 2012. APS / Alan Stonebreaker.

This apparatus, held in London's Science Museum, has some significant purpose — or curiosity value — in the history of physics. Can you guess what it is? In 1937, George Paget Thomson followed ...

The team cooled the helium-3 down to a hair above absolute zero (-273.15 °C, or -459.67 °F), then created two time crystals in the superfluid and let them touch.
