I'm having trouble understanding a certain part of Stephen Hawking's book A Brief History of Time. Can someone put this in other words so I can understand?Suddenly I realized that the paths of these light rays could never approach one another. If they did, they must eventually run into one another. It would be like meeting someone else running away from the police in the opposite direction – you would both be caught! (Or, in this case, fall into a black hole.) But if these light rays were swallowed up by the black hole, then they could not have been on the boundary of the black hole. So the paths of light rays in the event horizon had always to be moving parallel to, or away from, each other. Another way of seeing this is that the event horizon, the boundary of the black hole, is like the edge of a shadow – the shadow of impending doom. If you look at the shadow cast by a source at a great distance, such as the sun, you will see that the rays of light in the edge are not approaching each other.
I would not want my rod grounded to anything that comes in my house. Buy a 8 ft. metal ground stake. Drive it all the way in the ground outside. Connect the lead from the rod to the stake you just drove up with a clamp.
Try and reboot into Safe Mode. Once the screen is black, start tapping the F8 button. Continue tapping the F8 button until the start screen appears indicating the you are in Safe Mode. You should then be able to restore.
You can't use the system restore function of Windows without accessing the Control Panel. Install a good anti virus like Kaspersky. Then boot into safe mode by holding f8 when the computer loads. Do a full scan. Restoring your system will not allow you to get rid of the virus.
