This is the context:
the multiverse is just an example of a bad theory. The multiverse theory can predict nothing. But can it accommodate anything? Oh yes. It can accommodate everything because it is a multiverse and one can find the right place in the multiverse. It’s a remarkably imprecise theory. The amazing thing is that people have welcomed it. They should have flung their hands up.
I searched on the internet and just found one explanation from the Cambridge dictionary:
to show that you are very shocked or frightened.
Is this definition applies here?
