The comments are very interesting and here is a great question with an answer:

Commenter Nick Harris asks:

Dark energy is devouring and gradually replacing dark matter” What does that even mean??

Omar Nasr has a great answer:

It is thought that dark energy is the force that causes the universe to expand although scientists aren’t exactly sure how…. and if this were the case it would mean that dark energy is doubling in some way as the universe is expanding exponentially and since scientists abide by the law of conservation of mass and energy it can only be thought that dark matter is turning into dark energy like some of the mass from two hydrogen atoms fusing in the sun turns into energy….. In simple terms the universe is expanding at an ever increasing rate expansion is caused by dark energy so dark energy is increasing meaning that by laws of conservation dark matter is being converted to dark energy… Hope this helps

We hope this video inspires you and keep learning about science!  And if you have any theories of your own feel free to post them in the comments section.
