Dear Faouzi, 

No, quantum physic say that there are no time and no space. In fact, they don't exist in a determinate time but they are continuously "built". 

I checked your profile, you are a scientific researcher, great! and yes I agree to add you because Allah asked us to search for knowledge from cradle to grave  :-)

"Does time and space exist in quantum physics"

"Has anyone read about the thought experiment called "Schoringer's cat"? 

In English, we use 's to show possession. For example, "Michelangelo's David" or "the girl's cat" and if there were multiple girls, it would be "the girls' cat".

Dear Karima,

Firstly Let me correct this : quantum physics '(in french physique quantique),schrodinger  Schôringer

I am so surprised to find a scientific subject like this on Italki.

So in quantum there is two different states of particle exist simultaneously, the experience of Schrödinger's cat is to make a cat in a sealed box with a flask of poison and a radioactive source 

If an internal monitor detects radioactivity , the flask is shattered, releasing the poison, which kills the cat, and if not the cat still alive

and according to two different states of particle, So the internal monitor detects and does not detect radioactivity simultaneously, So the cat is simultaneously alive and dead.

Do space and time exist in quantum physics?

I Think yes because in quantum we justify this by existing the Parallel universes, in the univer the cat is dead and in the parallel univer the cat is alive.

It would be great to make a scientific discussion where we can grow our knowledge and improve our english level, If you don't mind, please add me.
