It was tens of thousands of times more massive than the ones our Sun puts out.
The Universe’s densest stars have a maximum mass limit, researchers find
Stopping just shy of a black hole’s density, neutron stars play a dangerous game.
What is mass? Baby don’t weigh me – revamping the metrology of mass
The metric system is due for a mass makeover, as scientists are preparing to redefine four basic units by the end of 2018 in an effort to provide accurate measurements at all scales.
Dropping weights in space to test Einstein’s general relativity
Extraordinaire experimental physicist Galileo Galilei allegedly climbed hundreds of step to reach the top of the Leaning Tower of Pisa’s – which wasn’t so leaned as it is today – and dropped pairs of balls of different weights and materials onto the ground. The experiment was meant to prove in front of the crowd of scholars and students gathered in front
Mass of the electron re-weighed for a precision of parts per trillion
Typically in physics, your calculations and such are as precise as your use of constants. Meaning, if you have a skewed value for your constant, this will obviously affect all the computations where this constant is used. Today, all the important physical constants are rather precisely known, whether we’re talking about the speed of light or tau mass. For most
2013 Nobel prize in physics awarded to ‘God particle’ scientists: Peter Higgs and Francois Englert
Just a few moments ago, the Royal Swedish Academy of Sciences awarded this year’s Nobel Prize in Physics to Francois Englert and Peter Higgs on Tuesday for their 1964 postulation of the existence of the Higgs boson. The elementary particle was finally confirmed in 2012 by a team of international researchers using the Large Hadron Collider at CERN. The July 2012
How much does a kilogram weigh? The struggle of keeping standardized mass constant
Since 1889, the world has used the International Prototype Kilogram (IPK) – a cylindrical chunk of metal the size of a matchbox stored in a French vault – as the standard for measuring one unit of mass. Some 40 replicas were made and shipped to countries through out the world such that an international standard could be put in place.
Neil deGrasse talks about e=mc^2
Neil deGrasse is definitely one of my heroes, and the simplicity through which he manages to explain even the most complicated things is absolutely amazing. After the symphony of science, here’s him in a short video talking about what is perhaps the most important equation to date.
