Are people evolving towards something more intelligent?

people will spend more and more time in virtual reality. The changes are said to be as profound as the evolutionary gap between apes and humans.

Are people evolving towards something more intelligent? Is it in human genes that people will become smarter in the next generations?. My guess is that the gap between intelligent and intellectually challenged people is widening. While the average value remains unchanged.

Since the earth is around 30 times further away from the moon than its diameter, you can have a different angle of view of the moon up to 1.2 degrees.

The answer is a classic yes and no. In general, the moon has an earth-bound orbit, which means we always see the same side. Always and everywhere. While the earth rotates once in 24 hours, the moon moves about 1/30 on its axis. This hardly changes the angle between the sun, moon and earth. So the phases of the moon… Continue reading Does the moon look the same everywhere?
