M87- A super massive black hole- Mystery of Galaxy

Welcome to my blog "Mystery of Galaxy".  The Event Horizon team released the spectacular image of the black hole at M87.  It's also been a little bit of an obsession of mine to really understand exactly what it is we are seeing and what we are not seeing in this image. So let's take a deep look into the abyss, to the very edge of space and time as we know it. M87 blackhole source: Event Horizon Telescope / CC BY For starters, this black hole is located at the center of M87 ,a giant elliptical galaxy about 53 million light-years away in the constellation Virgo . And M87 is one of the largest galaxies in our local universe, and may have a mass as great as 200 times the Milky Way. The dominant feature of this image is a five thousand light-year jet.

Although the jet appears to be pointing toward ...

White holes - A theoretical concept that might be exist in reality- Mystery of Galaxy

White hole Welcome to my blog “ Mystery of Galaxy” .  An artistic representation of a white hole. Source: NASA’s Goddard Space Flight Center/Discover   From the mathematics of Einstein’s general relativity comes an object so peculiar, a white hole. The white holes twin of a black hole, was first thought of in the 18th century by the geologist John Mitchell . In those days, black holes were not considered to be real, Einstein even assumed they didn’t exist. Yet Einstein’s theory of general relativity predicts and allows a concept named a white hole. More specifically it’s the mathematics of general relativity that say that white holes are possible. If you take the mathematics of a black hole and literally reverse it, you get a white hole. Or even, a white hole is a time-reversed blackhole. So, a black hole will not allow any matter to escape, once the matter is cross the event horizon, an imaginary boundary around a blackhole where no matter can escape after passing it. And ...
