El vacío tiene energía, como sospechaba Tesla. Pero la cantidad de energía es probablemente demasiado pequeña para ser utilizada como una fuente de energía útil.
We recall that the warping of the bedsheet was determined by the presence of the rock. Einstein summarized this analogy by stating: The presence of matter-energy determines the curvature of the space-...
The results of these and other studies were eye-opening. The children who exhibited delayed gratification scored higher on almost every measure of success in life: higher-paying jobs, lower rates of d...
The Fate of the Earth, points
Someday in the next thirty years, very quietly one day we will cease to be the brightest things on Earth. –JAMES MCALEAR
Si una idea no parece absurda de entrada, pocas esperanzas hay para ella. ALBERT EINSTEIN
Of course, the set of logically consistent mathematical structures is many times larger than the set of physical principles. Therefore, some mathematical structures, such as number theory (which some...
Max Planck once remarked, Science cannot solve the ultimate mystery of Nature. And it is because in the last analysis we ourselves are part of the mystery we are trying to solve.
Mahatma Gandhi escribió: Las raíces de la violencia: la riqueza sin trabajar, el placer sin conciencia, el conocimiento sin carácter, el comercio sin moralidad, la ciencia sin humanidad, el culto sin...
Let us discuss these problems in some detail. One problem is to amass enough energy to rip the fabric of space and time. The simplest way to do this is to compress an object until it becomes smaller t...
Kerr found that a spinning black hole would not collapse into a pointlike star, as Schwarzschild assumed, but would collapse into a spinning ring. Anyone unfortunate enough to hit the ring would peris...
Kaluza also gave an answer as to where the fifth dimension was. Since we see no evidence of a fifth dimension, it must have curled up so small that it cannot be observed. (Imagine taking a two-dimensi...
In other words, our destiny is to become the gods that we once feared and worshipped. Science will give us the means by which we can shape the universe in our image. The question is whether we will ha...
If you remove a single transistor in the digital computer’s central processor, the computer will fail.
If at first an idea does not sound absurd,then there is no hope for it. – ALBERT EINSTEIN
Hay un viejo dicho que reza: «Ten cuidado con lo que deseas, porque igual se hace realidad». El Santo Grial de la nanotecnología es crear el ensamblador molecular, o replicante, pero, una vez que esté...
Galileo believed that science and religion could coexist. He wrote that the purpose of science is to determine how the heavens go, while the purpose of religion is to determine how to go to heaven. In...
Fourth is Lambda, the cosmological constant, which determines the acceleration of the universe.
But if I make an observation, what is to determine which state I am in? This means that someone else has to observe me to collapse my wave function.
Already physicists are doing the basic calculations necessary to make an MRI machine fit into a cell phone.
