why can't gravity be renormalized?? i am just a novice in quantum physics...so i wud request to have an answer in a less technical way...
 
Physics news on Phys.org
Do you understand what renormalization means, and why electromagnetism *can* be renormalized?
 
i do understand wat it means...but of course i don't know the complete mathematics involved in it...correct me if my concept is wrong...it is a method used to cancel the infinities that come up in quantum field theories...on the other hand...how much i understand...electromagnetism is renormalizable becoz the quantum of light photon is a spin 1 particle...whereas graviton is a spin 2 particle...and so non-renormalizable...but y??
 

Thread 'Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
