"The distance any signal has to travel is astronomical - so it will be weakened by an astronomical amount squared. It has been said that SETI is like looking for a needle in a haystack. But if the instruments proposed by this group are built, SETI scientists will stop sifting the hay with spoons; they'll have a pitchfork." As this article focused primarily on the future of SETI, as one may have assumed from the title, it shall be very helpful while I am writing a draft on the theme. Since this article is in a well-known and respectable science magazine, I can conclude that "The Future of SETI" is a reliable source.

"Beyond listening for deliberate signals, SETI scientists could conceivably find extraterrestrial transmissions that weren't meant for us, just as our radio and television signals have been leaking into space this century." This pdf gave some very helpful information on SETI. I gained much knowledge about the background of this theme and will definitely be able to use what I have learned while writing my paragraph about this theme. To make sure that this was a reliable source, I did a bit of research on the author. Dr. Steven Garber is the founder of the Washington Institute and is the Scholar-in-Residence of the Council for Christian Colleges and Universities, leading me to believe that this pdf is a very dependable source.

"Europa is an icy world slightly smaller than Earth's moon. It is unique in the solar system, being thought to have a global ocean of water in contact with a rocky seafloor. If the ocean is proven to exist, Europa could be a promising place to look for life beyond Earth." It's not Europe, it's Europa. Europa is one of the 63 discovered moons of Jupiter, which may be able to sustain life if it is carefully colonized. There is thought to be twice the amount of water on Europa than on Earth, and signs of energy are making scientists want to learn more and more about the somewhat distant moon.

"The Terrestrial Planet Finder (TPF) uses a small collection of high sensitivity telescopes (probably 4 large 3.5-meter telescopes) with revolutionary imaging technologies. It will measure the temperature, size, and the orbital parameters of planets as small as our Earth in the habitable zones of distant solar systems. Also, TPF's spectroscopy will allow atmospheric chemists and biologists to use the relative amounts of gases like carbon dioxide, water vapor, methane and ozone to find whether a planet might support life. The launch was to be anticipated between 2012-2015 until NASA's budget cuts." The Terrestrial Planet Finder was discussed in the book Physics of the Future. This object will have better optics and will be approximately 100 times more sensitive than the Hubble Space Telescope. Its infrared sensors will be able to nullify the intense radiation from a star by a million times, revealing planets that have been undiscoverable otherwise. This radiation will even have the power to completely remove a star from the universe, if one ever so desires. The Terrestrial Planet Finder is predicted to be an extremely valuable tool to astronauts and scientists within the next century.

Touchscreen technology will expand beyond fingertips, evolving to incorporate artificial intelligence, light and even sound.This year's Computer Human Interface conference featured several new touchscreen inventions, as over 2,500 international researchers presented their work in Austin, Texas. Scientists and inventors showcased everything from medical to social networking and gaming-related touchscreen technologies, touching on a variety of intriguing directions that interfaces will take in the future.

Dailymail.com, which is a website for people to keep up with news without having to watch it, recently wrote about what the environment may be like in the future. By 2100, the Earth's temperature could increase by four degrees celsius, putting our world into a global warming crisis. Carbon Dioxide is hurting our planet more than expected, causing our ozone to keep the heat from the sun in. The website has been giving information to the public for years now, making it somewhat reliable to us for the sake that they always have a large audience. Dr. Sherwood, a knowledgeble man in meteorology, states,"Rises in global average temperatures of this magnitude will have profound impacts on the world and the economies of many countries if we don't urgently start to curb our emissions."
