This idea that we understand everything about the laws of physics at our ridiculously immature stage of development and having experienced the universe to the equivalent extent of a single grain of sand on a single beach in a universe of infinite beaches, is just staggering.
Yes, the laws of physics are the laws of physics. Period. But to assume we now understand them fully is laughable. As is the argument that there is no evidence that our understanding of them is incomplete. Of course there isn't, otherwise we would understand more.
Ask scientists about the laws of physics 300, 200, 100 years ago and you will see a progression in knowledge and understanding. Ask them again in another 100, 200, 300 years and you will see the same progression in knowledge and understanding. As long as we survive as a species until then.
Do I think there is alien life out there? Very probably, almost guaranteed. Advanced? Probably somewhere. Will they make contact? Probably not, why would they? Have they visited the earth and left technology with the Americans? No chance.
All imho, of course.
