EU theory contains a lot of supposed explanations. I do it injustice (as do themselves) by labelling it as one all encompassing theory. It becomes easier to dismiss as a whole since not every single thing presented under the umbrella might be truthful.

That being said, here's one that you might benefit from thinking about. The modern explanation of redshift from astronomical bodies seems just plain wrong. Why? There are large currents of plasma which are observed to connect two objects whose measured redshift (according to mainstream astrophysics) would put them at different sections of the universe.

Since we use redshift to make assumptions about the nature of spacetime, the big bang and an accelerating, expanding universe; the latter invoking necessary dark matter and dark energy (a purely theoretical, abstract idea by scientists which might never be found experimentally) this point deserves more credence than other points which fall under EU.
