Where Do Space, Time and Gravity Come From? | Quanta Magazine

Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host...

Gravity processes large objects:for example,the mass of the sun is 2x10^ 33 grams or the mass of the earth is 6x10 ^ 27g, not to mention much larger objects!Quantum physics deals with magnitudes of the order of 10 ^-43 seconds or 10 ^ -35 cm. It is impossible to connect directly!

Gravity at the quantum particles levels is so weak that might be even impossible to detect. Space, time and gravity come from the infinite space/vacuum as subnuclear particles when universes are from

A universe made up of quantum wavefunctions doesn’t easily mesh with Einstein’s description of curved space-time 🤣
