What are everyone’s thoughts

I don't like it.
It's not based on fact - it's just more hypothetical extrapolation and not going to get us out of this quagmire.

“We know that there is no viable [dark matter] candidate in the [standard model of physics]"

There is also no 5th dimension in the standard model so now we have two problems instead of one.
