A team of scientists monitored the Milky Way galaxy's center to test Einstein’s theory of general relativity.
Whereas general relativity took a single genius (Einstein) a decade to create, that deeper theory -- known as a quantum theory of gravity -- has flummoxed generations of geniuses for a century.
In Einstein's modern turn of phrase, what haunted Newton was "spooky action at a distance." How can two celestial bodies
There have been many scientific highlights of physics and astronomy in recent years: the Higgs Boson, landing a probe on a comet, and an amazing fly-by of Pluto. But all this is dwarfed by what has been announced this week. A new era of science has begun.
It has been contended that since something cannot come out of nothing, emergence therefore requires that all emerging properties
Gravitation proved to be far more than its jumble of equations, nonlinear structure, and famous text-boxes. Though several newer textbooks have displaced the book from graduate students' syllabi, none has rivaled the book's cross-over appeal.
This month marks the 100th anniversary of Albert Einstein's theory of general relativity. Amid all the celebrations and conferences, it is easy to forget about the real human being who actually did it. But if you live in Princeton, and his piano is in your living room, he is always present.
For someone who is determined to get propellantless propulsion off the ground, I worry that there isn't enough experimental research to make propellantless propulsion a reality sooner rather than later.
On November 25, 1915, Albert Einstein finally announced the complete mathematical details of his General Relativity Theory in the last of a series of four papers, but gravity and the nature of space itself, remain as mysterious today as they were back then.
