an a few minutes, the program kicks in and processes data while youre not using it. After a few days, a message on your screen will tell you that the data has been processed and you have to connect to the Internet and the data will automatically upload to Berkeley. (Naeye, 1998)Some astronomers pointed out that we maybe the only kind of life form in the universe. Mario Livio, an Astronomer at Space Telescope Science Institute in Baltimore, makes the case by connecting between the suns lifetime and the appearance of intelligent life on earth. This link should hold true for the stars that are similar to our sun in the universe and can offer an equal opportunity for intelligent life forms to arise elsewhere in the space. (Villard and Livio, 1998)Livio argued that based on life first emerged on earth a few hundred million years after its formation, it took nearly 3 billion years fro the first multi-celled organisms to appear. It took almost another billion year before life emerged from the sea onto the land. The earliest humans appeared less than 4 million years ago, which is about a quarter point of our suns lifetime. (Villard and Livio, 1998) If all of that was just a coincidence, it is very possible that other civilizations had to take much longer to arise, or even take longer than the life of a star.Livio also argued that as sunlight provides far more energy for life than other chemical processes, biological evolution is intimately linked to the Suns behaviour. (Villard and Livio, 1998) Only a small minority of stars, like our sun, can support complex life. Low-mass stars have a tiny zone in which a planet can support life. But that zone is so colas to the star that the planet will be tightly locked, so only one hemisphere receives sunlight. High-mass stars have large life zones but these stars die before life can evolve on the planets. Planets in multiple star systems may end up with unstable orbits or orbits that result...
