Atomic Clocks Experiment Reveals Time Dilation at The Smallest Scale Ever

by

In his theory of general relativity, Einstein predicted something called time dilation: the notion that two clocks under two different gravitational pulls will always tick at different speeds.   The effect has been observed in many experiments since, but now scientists have recorded it at the smallest scale seen so far. The result was achieved using … Read more

Strange Quantum Object Successfully Created in The Lab For The First Time

by

Quantum mechanics – the behavior of the Universe at the smallest of scales – continues to surprise us, with scientists now having been able to successfully create a quantum object called a domain wall in laboratory settings.   For the first time, these walls can now be generated in the lab on demand, occurring when … Read more

AI makes simulations of huge amounts of molecules possible

by

Computer simulations of clouds of atoms and molecules must always trade scale for accuracy, but a new technique shows that both are possible at once using AI and clever coding Technology 12 January 2022 By Matthew Sparkes The Summit supercomputer at Oak Ridge National Laboratory, Tennessee ORNL and Carlos Jones Artificial intelligence has been used … Read more

Physicists Observe Incredible ‘Quantum Tornados’ Formed From Ultra-Cold Atoms

by

Scientists have observed a stunning demonstration of classic physics giving way to quantum behavior, manipulating a fluid of ultra-cold sodium atoms into a distinct tornado-like formation.   Particles behave differently on the quantum level, in part because at this point their interactions with each other hold more power over them than the energy from their movement. … Read more
