[L]iking something is very important evolutionarily, because most things are harmful to us. Of the millions of objects that we bump into every day, only a handful are beneficial to us. Hence to like s...
We have not yet figured out why there is more matter than antimatter in the universe. Only one ten-billionth of the original matter in the early universe survived this explosion, and we are part of it...
To impress my Ph.D. students with just how bizarre the quantum theory is, I sometimes ask them to calculate the probability that their atoms will suddenly dissolve and reappear on the other side of a...
There isn’t an equation that can confirm something as self-evident (to us humans) as muggy weather is uncomfortable or mothers are older than their daughters. There has been some progress made in tran...
There are many advantages to space solar energy. It is clean and without waste products. It can generate power twenty-four hours a day, rather than just during daylight hours. (These satellites are al...
The transition between our current Type 0 civilization and a future Type I civilization is perhaps the greatest transition in history. It will determine whether we will continue to thrive and flourish...

Our eyes also fool us into thinking we can see depth. The retinas of our eyes are two-dimensional, but because we have two eyes separated by a few inches, the left and right brain merge these two imag...
One day , would it be possible to walk through walls ? To build starships than can travel faster than the speed of life? TO READ OTHER PEOPLE'S MIND ?To become INVISIBLE ? To move object with the powe...
One consequence of this formulation is that a physical principle that unites many smaller physical theories must autoomatically unite many seemingly unrelated branches of mathematics. This is precisel...
Normally gravity would crush the throat of the wormhole, destroying the astronauts trying to reach the other side. That is one reason that faster-than-light travel through a wormhole is not possible....
Normally communication between these universes is impossible. The atoms of our body are like flies trapped on flypaper. We can move freely about in three dimensions along our membrane universe, but we...
No obstante, la comunidad científica está dividida con respecto a la cuestión de si el increíble sueño de crear una nanofábrica es físicamente posible. Unos pocos, entre los que se encuentra Eric Drex...
Mediante las señales que emiten sus cerebros, los trabajadores entran en contacto telepático con los robots. Desde sus cápsulas pueden ver y sentir todo lo que los robots ven y sienten. Es como estar...
