We should only have to 'prove we are human' once a week (or so). Store a cookie or something, that expires in seven days, that tells you that this IP address is a human.
Your physics is way off. The rotation of a planet is not the source of the gravity of that planet. If it were then Venus would have next to no gravity.
"Malus is a genus of about 30–55 species of small deciduous apple trees or shrubs in the family Rosaceae, including the domesticated orchard apple. The other species are generally known as crabapples, crab apples, crabs, or wild apples."
I disagree. For us to survive interstellar travel we would need to change our physiology. We would need the ability to, individually, live hundreds of years. And do so while surviving cosmic rays and other, similar, radiation that is lethal to us in our current state.
In short, we would have to become more machine than human.
Any civilization advanced enough to make interstellar travel viable would already possess the ability to satisfy their needs/wants without disturbing us.
I am vastly superior to an ant. I have the ability to travel hundreds of miles in one ant lifetime. So, let's say I come across an anthill. Do I kill them all? No. Do I take from them something they deem valuable? No. In effect, I totally ignore them. I don't even try to communicate with them. To deal with them in any fashion is just a waste of my time.
The same would happen with an extraterrestrial species coming upon us. We would be ignored. We would be just a waste of time to any alien able to travel between the stars.
Assuming the distances are as difficult and timrtime consuming to traverse for them as it is for us then there is no realistic concerns about one civilization becoming the slaves of the other.
So that leaves communication with each other. We would craft meaningful messages and send them to the other planet. Then we would wait years or decades for a reply. Then we can would analyze the heck out of the reply. And then try to crafts the a meaningful response.
The Korean War served its purpose in thatthat it gave the US government a war in which it could send the excess soldiers from WWII, remaining in the service. Without a war to send them to they would have returned to the US without jobs and possessing the ability to kill. TheThe Korean War kept them out of polite US society.
I would like to accomaccommodate your request. However I learned about this via a TV show on PBS. The show was hosted by a neurologist by the name of David Eagleman. The show mostly focused on his work, but I think that the study I referent 3 was done by some other person or group.
But I give you a link to Eagleman's site.

Recent neurological research indicates that our left-or-right political outlook is 'hardwired' by genetics. If you have a 'disgust reaction' that is easily triggered then you have a 95% chance of being conservative in your politics.
So arguing politics appears to be useless with 95% of the potential listeners. So arguing here is a waste of time.
