We are all now connected by the Internet, like neurons in a giant brain.

To make a movement, the brain takes the electrical activity of many neurons and combines them to make muscle contractions. But the movements aren't always perfect. So we asked, what gets in the way?

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.

I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.

It takes a bit of physical attraction to be interested in knowing someone. Let the eyes work, the neurons sends the message to the brain and process the message there. If there is no spark , then there's nothing there.

It now appears that the way the universe began can indeed be determined, using imaginary time.
