"...be a physicist because all you need to remember are the fundamental laws of nature and everything else is derived from them."

UNLESS, Simulation Theory proves to be right, then the laws of nature are a lie, simply game mechanics that can be turned off and on by agencies that have authority to do so.

What if our cosmos was just a simulation on alien computer siting on desk... Wait wait wait. I think you proposed that thought experiment! Or was it maybe Doctor James Gates .

In terms of Oumuamua, that's a home run there. At some point, Occam's razor will have to be 'it's aliens.' Explanations and arguments are not absolute, just methods to align what we see to what we know.

What we know could be wrong. UFOs might be able to go through mediums like air and water, maybe even solid earth, in ways that defy our understanding of physics. We might not have physics pinned down to the degree we think we do. Physicists being wrong, human enough. No more an insult, than fellow who say with 100 percent certainty. People have placed bets and been wrong before. It's happened. Is truth absolute or perspective based? Physics is probability based at some level, right? People get things wrong, mostly when they're basing their truth on their understanding of how the world works. Right enough most the time to earn a living on it. So, maybe we shouldn't dismiss reports of UFOs accelerating past the speed of sound without creating sonic booms or fire trails?
