Maybe Black Holes Go Nowhere

Astronomers estimate that the Milky Way has wherever from 10 million to 1 billion stellar black holes, with masses roughly three times that of the sun. In 2015, astronomers using the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves from merging stellar black holes. Albert Einstein first predicted the existence of black holes in 1916, with hisgeneral principle of relativity.

Simulated view of a black hole in front of the Large Magellanic Cloud. Note the gravitational lensing effect, which produces two enlarged but highly distorted views of the Cloud. Across the highest, the Milky Way disk appears distorted into an arc.

As such their frequency is linked to the mass of the compact object. They can thus be used as an alternative way to determine the mass of candidate black holes.

This odd property led Gerard ‘t Hooft and Leonard Susskind to suggest the holographic … Read More

On 11 February 2016, the LIGO Scientific Collaboration and the Virgo collaboration introduced the primary direct detection of gravitational waves, which also represented the primary statement of a black hole merger. As of December 2018[replace], eleven gravitational wave events have been observed that originated from ten merging black holes (together with one binary neutron star merger).

They got down to seize an image of a black hole by enhancing upon a technique that enables for the imaging of far-away objects, known as Very Long Baseline Interferometry, or VLBI. Most black holes are too far away for us to see the accretion disk and jet. The only approach to know a black hole is there is by seeing how stars, gasoline and light behave round it.

The concept of common relativity predicts that a sufficiently compact mass can deform spacetime to kind a black hole. The boundary of the area from … Read More
