The term black hole is of very recent origin. It was coined in 1969 by the American scientist John Wheeler as a graphic description of an idea that goes back at least two hundred years, to a time when there were two theories about light: one, which Newton favored, was that it was composed of... »read more

How many stars are there in the universe?

Look into the sky on a clear night, out of the glare of streetlights, and you will see a few thousand individual stars with your naked eyes. With even a modest amateur telescope, millions more will come into view. Stars are not scattered randomly through space, they are gathered together... »read more

Black holes are the densest, most massive singular objects in the universe.

  In the 1700s, there were some who proposed that a super massive object might draw light into it. Newtonian optics was a corpuscular theory of light, treating light as particles. The idea of a body so massive that even light could not escape was put forward by geologist John Michell in a... »read more

Last summer, Yale physicist A. Douglas Stone and his team published a study explaining the theory behind an anti-laser, demonstrating that such a device could be built using silicon

More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel... »read more

Genetic engineering is the process of manually adding new DNA to an organism.

Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms. Genetic engineering is different from traditional breeding, where the organism's genes are manipulated indirectly. It uses the techniques of molecular cloning and transformation to alter... »read more
