"No, scientists have found no clear indications of life, past or present, beyond the Earth. There have been several tantalizing suggestions - that the Viking mission might have detected evidence of microbial life on Mars or that there are fossil microbes in some Mars rocks or meteorites - but none of these claims has been verified." Although this link is simply the Frequently Asked Questions of the SETI Institute, I have found this extremely helpful because many questions that I had were answered (hence the "Frequently Asked Questions"). These questions are about life that we have found past the Earth, why people insist that "life is out there", and even how scientists at this institute are examining global warming to find the effects. As this article is on the website of the SETI Institute, which consists of some of the best scientists in the world, I think that it is safe to assume that this is a valid source.

"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.

"So the main danger we face from an advanced civilization is simply that we might get in their way." This is an interview with Michio Kaku, where he talks briefly about SETI. Here, he talks about how silly it would be to "advertise our existence in space" (Kaku) because we might find a civilization that is a million years ahead of us in terms of technology, and would therefore be crushed. Kaku uses examples such as a fruit fly versus Goliath, to compare to what might happen if we were to find such a civilization. This is helpful, as it gives me an idea as to where Kaku stands on the subject. I trust that this is a reliable source, as I found a link to it on Michio Kaku's website.

"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.

"Growing at the average rate of about 3% per year, however, one may calculate that our own civilization may attain Type I status in about 100-200 years, Type II status in a few thousand years, and Type III status in about 100,000 to a million years." Michio Kaku's website has some great articles that have to do with our topic. This article, in particular, has information on types of civilizations. I know that this is a reliable source because it is on Kaku's website.

"We are on a search for who we are. What does it mean to be a human? Can there be more than one kind of human? In fact, what exactly is a human?" In this article on Huffington Post, Kevin Kelly addresses the fact that we, as humans, do not really know who we are as well as questions the authenticity of what is around us. Growing technology and the internet make people question their identities even more, as they may enable us to change our physical features, as well as make people question what is real. Upon further research, I have found that Kevin Kelly was a co-founder of the Wired magazine and has recently gotten a book, What Technology Wants, published. I feel that this online article is a very reliable source based on the aforementioned information about the author and I to think about the questions that Kelly brought up while I read Physics of the Future.
