Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of surviv...
Beyond work and love, I would add two other ingredients that give meaning to life. First, to fulfill whatever talents we are born with. However blessed we are by fate with different abilities and stre...
When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's...
Even if we mortgage the next 100 years of generations of human beings, we would not have enough energy to build a Death Star.
Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible...

The advantage of this interpretation is that we can drop condition number three, the collapse of the wave function. Wave functions never collapse, they just continue to evolve, forever splitting into...
El reconocimiento de patrones, como ya hemos visto, es uno de los principales obstáculos para la inteligencia artificial.
Democracies are slow to anger and hesitant to go to war: Voters don't want to sacrifice their children for the glory of a selfish king.
To create silicon chips, UV light is passed through a template that contains the blueprint for all the circuits on a chip. The UV light and a series of chemical reactions creates a pattern that is etc...
Men imagine gods to be born, and to have clothes and voices and shapes like theirs....Yea, the gods of the Ethiopians are black and flat-nosed, and the gods of the Thracians are red-haired and blue-ey...
