How can dark energy comprise 74% of the Universe?

In summary: So, in summary, the article claims that dark energy comprises 74% of the total mass of the universe, while dark matter comprises 94% of the total mass of the universe. I'm still a bit confused about how energy can comprise mass, but I'm guessing that it does something like change the way the laws of physics work for things with mass. Thanks for the summary!

Light has to cross the Hubble sphere to reach us.

That doesn't mean "they are related", or that the reason the observable universe will be larger in the future is that the Hubble sphere will.

In any case, this subthread is off topic, so please do not post further in it.
