Well, he was talking horse sense.

It was a feeble joke the first time. Repeating it doesn't make it any better.

Don't get me too enmeshed in the physics of that stuff, but what I said is how I understand it.

In other words, you don't understand it. Neither do I. You need advanced degrees in theoretical physics to even come close. (I started out in chemistry then moved into genetics and evolution.) We don't (and cannot) know whether any of it is true, we just have to trust that the people who are doing the work are following proper scientific principals. We come dangerously close to taking it on faith.
