A different kind of Black Hole; Primordial Black Hole By theories concerning black holes, in addition to black holes that are formed by the process of stellar gravitational collapse, black holes also formed within the first second of the Big Bang, before the existence of stellar bodies. The black holes that are formed soon after the BigBang are the Primordial black holes.
For the First Time Astronomers Captured the Gravitational Waves from an Unevenly Sized Black Holes On April 18, 2020, the LIGO Scientific Collaboration and the Virgo Collaboration announced one more discovery of gravitational waves from...
MIT Engineers Devised a New Decision Map to Identify the Best Mission Type to Deflect an Incoming Asteroid It is predicted that on April 13, 2029, that icy chunk will be at the planet Earth's sphere of geostationary satellites- a location in Earth's gravity field. After this, the asteroid will be on its next flyby and as predicted in the year 2036, it would likely make a devastating impact hitting the Earth's surface and most scientists believe it is never too early to consider strategies for deflecting an asteroid if one were ever on a crash course with our home planet.
If We Can't see Black Holes, How are they Detected? One way of detecting the black hole is by their gravitational influence and another way of detecting a black hole is by observing the matter falling into the black hole. Another way of detecting a black hole is by observing the matter falling into the black hole.
What is Black Hole Evaporation or the Hawking Radiation Hawking claimed that considering the quantum phenomena, black holes are not totally black: they should glow slightly with radiation that consists of photons, neutrinos, and to a lesser extent all sorts of massive particles. This idea of Hawking solved the unsolved mystery of black hole i.e. entropy problem of the black hole.
How Hawking Radiation appears; What really happens inside Black Hole? The idea Stephen Hawking used was when a black hole absorbs new materials using its immense gravitational pull then the entropy of those falling materials must go on adding the overall entropy of black hole.
Solar Wind Problem Finally Solved It is crucial to understand the characteristics of the solar wind and recently this will be probed at distances unprecedentedly close to the Sun by the new Parker Solar Probe mission, named after living Eugene Newman Parker and was launched on August 12, 2018.
More Advanced Detection Technique of Gravitational Waves - LIGO Equipped with Quantum-Enhanced System but Why and How? Overall, the new quantum squeezers have enhanced the expected detection rate by 40% at LIGO Hanford and by 50% at LIGO Livingston. On Sept. 14 of 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) recorded the first-ever Gravitational Wave.
How Advanced LIGO Works and What we can Learn from Gravitational Waves? A gravitational wave propagating orthogonally to the detector plane and linearly polarized parallel to the 4-km optical cavities will produce the effect of lengthening one 4-km arm and shortening the other during one half-cycle of the wave; these length changes are reversed during the other half-cycle.
First image of a Black Hole (Part-Four); What Scientists Got? The main aim of this project was to image an event horizon for the first time and to help determine if Einstein’s theory of general relativity needs any revision. The EHT team successfully imaged the black hole with distinctive and clear event horizon and also claimed their study further confirmes that the general theory of relativity is right at its place, till now.
