How do you play downloaded games from the PlayStation store on your ps3?
Sometimes the games are in folders under the games section. You can use the options key and combine them by type or split them. You might have to first click the folder to open it and find your game. It depends on if you have downloaded it from the PlayStation Store, if you have you can access it by going to 'GAMES' on the User Interface, then scroll down to the title of your game. Games can only be downloaded from the Playstation store and then they are installed and available under the games section
How is the distance between earth and space measured?
Radar. No, seriously. Scientists have used radar to measure the distance to the Moon since radar was invented. (Nowadays they don't need to; the Apollo astronauts placed a laser reflector on the Moon to make it easier to measure the precise distance to the Moon any time the want.) For things farther out, parallax measurements between two observatories precisely measuring the angle between, say, Neptune and a nearby star will allow astronomers to measure the distance quite accurately anywhere in the solar system. They can even use similar techniques to measure the distance to nearby stars, although the angles involved are very tiny.
