Physics is poorly understood now? No, you're just beating around the bush now.
And we're the smartest people in the universe? No others can detect/communicate with us?
Enjoy your Thanksgiving dinner ...
Please include the full quote. I said: "Physics is poorly understood prior to the Planck epoch". Do you disagree? If you do understand the physics of the Big Bang prior to Planck epoch, I suggest you contact the Nobel Committee...your prize is waiting.
And we're the smartest people in the universe?
There is no evidence that any other "people" exist anywhere outside of Earth. This doesn't mean they aren't there, of course. Heck, I think it's likely...the universe is big.
No others can detect/communicate with us?
How exactly do you suggest they detect/communicate with us? Lightspeed delays mean that even if there's a highly technological civilization in the nearest major galaxy (Andromeda), it will take 2 million years for them to detect us, and 2 million more years for their message of, "Hi there...how ya doin'?" to get to us.
Enjoy your Thanksgiving dinner ...
And a happy Thanksgiving to you and yours.
