In general, the right side of the brain largely controls movements on the left side of the body, and the left side controls the right. Damage to this area on the right side of the brain can result in cognitive issues, as well as issues of control and muscle recognition on the left side of the body. One of the more interesting medical conditions that can result from right hemisphere damage from injury, surgery or illness such as a stroke, is Anarchic hand or Alien Hand Syndrome. AHS is a rare neurological condition where one hand basically seems to act on it's own. A person could be writing with their right hand, and if the left is affected by AHS, then the left hand might purposefully move to stop them, or take the pen away. One could lift a fork to one's mouth with a right hand, and the left hand could smack it away. The movements appear considered and deliberate and goal orientated, and a battle to keep things in one hand while the other hand tries to take them away is a common symptom. You could zip up your fly with one hand while the other immediately takes it down. It must be incredibly frustrating. It differs from other disorders in that the patient recognizes it as belonging to them, but it appears to have it's own will. It must be distressing to live with and thankfully it's rare since there is no cure for AHS. Drugs offer limited help, vocalizing commands to the rogue hand can sometimes help, and as a last resort strapping the hand down is used. Some people have even reported their hand as trying to hurt them. It seems a very unfair business to survive injury, stroke, surgery or whatever, only to be burdened with a rogue hand sabotaging your everyday life from slapping you awake to trying to choke you.

Fourier wrote: » This is a follow on to #7286 That post was basically about Special Relativity, this one is about General Relativity. It's a weirder subject so might not work as well, but I thought I'd still give it a go. So I've already introduced the fact that different observers timelines can be at angles from each other due to how fast they are moving with respect to each other. However all the timelines in that post were still straight/linear. All that General Relativity introduces is that the timelines can bend. This is a image of an observer near the Earth. The multiple copies of Earth just represent it at different points in time, but in the same place in space. Unlike the last previous images the little man's timeline is distorted toward the Earth. General Relativity states that a heavy object like the Earth will pull timelines of nearby objects into itself. Literally the Earth "grabs your future" and makes it point toward its core. Just by existing, doing nothing and letting time pass you'll move closer to the Earth, because your future now points toward the Earth. A black hole is a more extreme case. In this image Alice is far away from the black hole, Bob is near it. The edge of the black hole, the event horizon, is the red line. The green line marks everything that is 10 seconds from now according to Alice. The orange line is what remains of the star that created the black hole. What happens at the event horizon is that your timeline goes totally horizontal. From Alice's point of view Bob simply vanishes, because his timeline goes horizontal he can't reach parts of her future. For example he never reaches the green line which is space ten seconds from now for Alice. It's often stated that the reason you can't escape a black hole is because you'd need to go faster than light. This is wrong. You can't escape because your whole future, your entire timeline, is drawn into the hole. If you follow Bob's timeline, the only way out of the black hole involves following his timeline backward, i.e. travelling back in time, which is impossible. So he can't escape.
