Finding Aliens

Posted On Dec 13 2016 by

SETI (Search for Extraterrestrial Intelligence) project has been going on for decades. And we explored our solar system for signs of life. And we couldn’t even find microbial life outside Earth, let alone an intelligent civilization. But all the statistical studies and everything we know about life tells us that the universe should be teeming with life. Then, what is going on? I think the most likely possibilities are as follows:   We are too primitive We may be too primitive to attract their attention. Our stage of civilization may not be interesting to them, since they have seen many …


Key Issues in Science

Posted On Dec 13 2016 by

Even though there has been a lot of advances in science and technology in the last century, there hasn’t been any paradigm shifting revolutionary advance in our understanding of the universe since Einstein. Everything has been accomplished within the framework of the 20th century physics. But we are hitting a rock with this understanding of the universe, and it no longer gives us new answers or expands our horizon. To make the matters worse, some issues that were being considered minor annoyances throughout the last century (regarding our understanding of the universe) are turning into matters that cause scientific crisis. …


Nuclear Fusion

Posted On Dec 9 2016 by

Humanity is very close to achieving a nearly endless and clean energy source. It is called nuclear fusion. It is different than the nuclear fission reaction that is used in today’s nuclear reactors. Nuclear fission is based on splitting large atoms such as uranium or plutonium, and even though it releases a great amount of energy, it also generates radioactive waste. But nuclear fusion is the way stars generate their energies, and it is based on fusing light atoms such as hydrogen to generate larger ones such as helium. This generates a huge amount of energy, and no radioactive waste. …


Population Increase and Its Implications

Posted On Sep 6 2016 by

World population keeps increasing. Humanity spreads all over the world just like a cancer, causes other species to go extinct, and changes the face of the earth. It was easy before civilization. And it still is, in the nature. Population increases geometrically (2,4,8,16,…), but food supply, or resources either don’t increase, or they increase arithmetically (1,2,3,4,…). This means more living beings than the resources could support, and the result is the survival of the fittest. The ones that fit the environment better or have advantages tend to survive, and the others die. And as many people know, this is the …
