What does the universe being not locally real mean?

Question

I just saw a comment that linked to an article explaining how Nobel prize winners recently discovered the universe is not locally real. My brain isn’t functioning properly today, so can someone please help me understand what this means?

Answer 1

You look at table, you can touch it, smell it, see it, knock on it, table is there, table will be there tomorrow unless you move it.

Now you look at table with microscope, table is gone, it is no longer there and you only see atoms.

Table does not exist for microscope, only for human.

Now replace “table” with “universe”
