On the contrary: look at what he is saying and then try to show why he is wrong. An emotive reply of "he contradicts currently accepted ideas" does not advance science much. Finding flaws in different explanations makes the current model stronger.
We know that the current model has holes in it, for instance it requires dark matter & dark energy - which we do not understand. Hopefully, in the not too distant future, these will be explained or shown to not be necessary by some tweaks to the current model -- but quite possibly by big changes to the current model.
