Actually, the closest object, that we're 100% sure it's a black hole, is the Sgr A* - a supermassive black hole in the center of our galaxy (about 26,000 lightyears) with a mass of about... Читать далее
Particle physics is the study of the building blocks of nature, answering fundamental questions about the pieces that the world is made from and how they interact. For forty years the... Читать далее
One of the most intriguing ongoing searches (at least for me) is the gravitational wave (GW) detection efforts being done by LIGO collaboration. We already know about at least two black... Читать далее
I once had the existence of time conclusively disproved to me by that renowned temporal physicist, Ol’ Dirty Bastard of the Wu-Tang Clan. Back in the ’90s I was interviewing him for The... Читать далее
Nothing. Time still passes even if objects stop moving.
So, even if the Universe stopped expanding and the planets stopped rotating, time would still go on. Similarly, whether you’re... Читать далее
Solar energy comes mostly from fusing 4 hydrogen nuclei (protons) into a single He-4 nucleus. About 90% of that energy is being generated in the deepermost 10% of the Solar core, since... Читать далее
I would define quantum theory as a set of rules governing how the universe works on a microscopic scale. By microscopic I mean on the scale of electrons and atoms. We know that the... Читать далее
The LHC is a discovery machine. It was not built to improve our material lives, but to understand the Universe in which we live. Its science goals are numerous, with three distinct types... Читать далее
With quantum theory you can calculate the probability of observing a particular outcome of an experiment or a measurement. But some events are very rare indeed. In the quantum football... Читать далее
Clouds give very good clues of the immediate status of the atmosphere, and sometimes what’s about to arrive – or not, depending on if it’s a stable condition or if it’s likely to... Читать далее
