Question

as dark enegy and dark matter existes between the stars and the galaxies of our universe does dark energy also existes between the universes in a multiverse?

Answer 1

The new research also lends believed to the idea of a multiverse. This theory posits that, when the universe grew exponentially in the first tiny fraction of a second after the Big Bang, some parts of space-time expanded more quickly than others. This could have created "bubbles" of space-time that then developed into other universes. The known universe has its own laws of physics, while other universes could have different laws, according to the multiverse concept.

More is unknown than is known. We know how much dark energy there is because we know how it affects the universe's expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe. Come to think of it, mamaybe it shouldn't be called "normal" matter at all, since it is such a small fraction of the universe.


so in short,,YES!

Yes, dark energy also exist between the universe in a multiverse.
same with dark matter too! a mulltiverse also expanding like our universe!
