Have you ever been in a loud, crowded room (remember those?) and thought you heard a familiar voice or your name being called? Something just loud enough to perk your ears up but not so loud you can be sure you heard it? An international team of astronomers is in that same situation right now. Except that the crowded room is the Universe, the people in it are colossal black holes eating each other, the voices are waves compressing spacetime, and instead of ears astronomers are using several doz...

Albert Einstein’s theory of general relativity profoundly changed our thinking about fundamental concepts in physics, such as space and time. But it also left us with some deep mysteries. One was black holes, which were only unequivocally detected over the past few years. Another was “wormholes” – bridges connecting different points in spacetime, in theory providing shortcuts for space travellers. Wormholes are still in the realm of the imagination. But some scientists think we will so...

Dark matter and dark energy are to remain dark! We know you can do this. By Christopher (not verified) on 16 Dec 2012 #permalink I had never seen a sky full of stars, and I do mean full, until I traveled to North Carolina for the first time. This was well into my 4th decade of life too! I was on NC17 between Elizabeth City and Edento...

For a scientist, few things are sweeter than data from an experiment that confirms a theoretical prediction. Frequently, however, scientists don't

    (For the Holiday Season, from Christmas through New Year’s Day. we’ll post 2020’s most viewed articles as ranked by Google Analytics) Albert Einstein described black holes as strange objects “where God divided by zero.” An international team of astrophysicists has now confirmed that black holes are a distinct “species” from neutron stars –comparable to black holes in mass and size but confined within a hard surface, unlike black holes, an exotic cosmic object without a har...

C.V. Vishveshwara in 2007 in Oak Park, Illinois. Namitha Vishveshwara For a scientist, few things are sweeter than data from an experiment that confirms a theoretical prediction. Frequently, however, scientists dont live long enough to savor that reward. Take Albert Einsteins prediction about gravitational waves. Einstein postulated their existence in 1916, but they werent detected until a hundred years later, long after the great physicist had died. C.V. Vishveshwara was one of the...

“Somewhere, something incredible is waiting to be known” - Carl Sagan It’s hard not to sit in wonder at the sheer scale of the Arecibo Telescope; the main dish was over 300m in diameter – so big that the easiest way to make it was to put it in a naturally formed sinkhole. She was, until 2016, the biggest radio dish ever constructed. What she had in scale she matched in scientific discovery; Arecibo was at the core of radio astronomy since her construction in 1963. In the 50 years since,...

Them was the ultimate punishment this idea challenged our uniqueness in the cosmos for a long time since Aristotle in fact we thought our solar system and the Earths place in it was a one and only that is there was one solar system in the cosmos and we were at its center the moon the sun and the visible planets all orbited Earth now jumping into the modern era and the idea of exoplanets that is planets orbiting other stars was tossed into the astronomical ring a century ago but there was no evi...
