The American cartoonist Matthew Inman published a brilliant comic titled “The Oracle” on his website “The Oatmeal”. Inman’s comic gives the most probable answer (IMHO) to Fermi Paradox, which can be summarized in these three words – “Where is everybody”.
Thomas Moynihan, University of Oxford It is 1950 and a group of scientists are walking to lunch against the majestic backdrop of the Rocky Mountains. They are about to have a conversation that will become a scientific legend. The scientists are at the Los Alamos Ranch School, the site for the Manhattan Project, where each […]
Earle Kyle I am one of the few African-American aerospace engineers who helped design the Apollo spaceships that took men to the Moon. My great-grandfather was a slave in Claiborne, Alabama, who used primitive tools to work the land. My father was born in Alabama before the Wright brothers made mankind’s first flight. He lived […]
According to a new study published in the May 2, 2019 issue of Nature, 4.6 billion years ago, two neutron stars collided near the early Solar System (actually about 1000 light years from the gas cloud that eventually formed the Solar System). This violent collision has created heavy elements like silver, gold, platinum, cesium, and […]
The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times […]
In 1964, Russian astrophysicist Nikolai Kardashev (born April 25, 1932) defined three levels of civilizations, based on the order of magnitude of power available to them (known as the Kardashev scale):
Currently, we’re slowly transitioning to renewables and fusion energy may become available in the future. If we don’t destroy ourselves or the environment, as humanity progresses further, we will likely gain complete control of the Earth’s resources. At that stage, we’ll probably begin to look outwards for new places to expand into. But, if we […]
Can we, humans, be one of the few (or the only) civilizations in the Universe that surpassed the so-called “great barrier”? Are we the first?
Is it possible for humanity to visit other stars (or other stars that have planets, actually) in the future? Earth is our one and only home. As Carl Sagan said (Pale Blue Dot: A Vision of the Human Future in Space), “On Earth, everyone you love, everyone you know, everyone you ever heard of, every […]
