The vast, seemingly empty spaces between galaxies are not entirely empty. So what's in these cosmic voids?

This headline is really lousy click bait!

It isn't until you get to the last paragraph, which says:
"Deep in the voids, however, dark energy takes over. It's the only thing left. This means that although the voids lack matter, they are filled to the brim with dark energy. And it's in the voids that dark energy is doing its work of tearing the universe apart."
that you see something was not discovered "hiding" there.

And, that it is there at all is pure hypothesis.

For all we know, "dark energy" may not even exist.

And, if it does, the theory has it everywhere, not just in "voids".

If you want us to believe that it is the voids that are forcing the universe to expand, at least make some sort of cogent argument, based on observations and facts, or at least theory, not just an unsupported assertion.
