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 so take t

This gas on atmosphere of Venus could be the sign of life outside of earth - Mystery of Galaxy

Possible sign of life on Venus Welcome to my blog "Mystery of Galaxy" . Today's topic is" Is phosphine the sign of life on Venus?" Venus Source: Pablo Carlos Budassi / CC BY-SA   Finding signs of life on other planets beyond the Earth would be away of answering the biggest questions that we've had as a species so far. Where do we come from? Are we alone? Deep within the acid clouds above Venus, astronomers have detected something new, a gas that could be a sign of life. The gas is phosphine, a toxic molecule with an odor of garlic and dead fish. Astronomers discovered the compound in a cloud layer where temperatures are fairly close to those on earth's surface. Phosphine is exciting because of where it comes from. On earth, it's either manufactured by humans, or it's a natural byproduct of life. It just doesn't show up anywhere else, and there's no human manufacturing on Venus. Phosphine is not sure fireproof there are alien microbes on t

Searching and exploration missions to discover Pluto- A mysterious dwarf planet | Mystery of Galaxy

Searching and exploration missions to discover Pluto Welcome to my blog" Mystery of Galaxy" . Over four billion kilometers away from us, lies a distant, frigid world. On its barren surface, nitrogen falls as snow. Vast plains of frozen methane lie in the shadow of ice water mountains. From the surface of this hostile place, the sun appears nothing more than a star, a single pinprick of light among millions. The name mankind gave this silent world Pluto . Discovered in the midst of the Great Depression by a former Illinois farm boy, Pluto was once the most mysterious planet in our solar system. For decades known only from blurry photographs, it finally became the focus of a NASA mission in 2006… only for the International Astronomer’s Union to controversially strip it of its planet status that same year. A dwarf planet that behaves like a comet, a lifeless chunk of rock that might be home to oceans, Pluto still grips our imaginations. Pluto Today we explore the history of th

Mystery- are white hole really exist?- Mystery of galaxy

 Welcome to my blog “ Mystery of Galaxy” . Today our topic is about the existence of white hole. Let’s get started. Are white hole real?  An artistic representation of a white hole. Source: NASA’s Goddard Space Flight Center/Discover Just like the elusive loch nests monster, a white hole is an interesting idea that has not yet been proved to be real, but there's no good reason why it couldn't be real. You see, white holes are highly speculative tales, told by astronomers to potentially explain what's on the other side of a black hole. So what exactly is a white hole, and do they really exist? Let's find out... A white hole is the exact opposite of a blackhole .   A black hole sucks in matter and no matter can escape it. Black hole Source: Event Horizon Telescope / CC BY Whereas a white hole spews out matter but matter cannot enter it, kind of like a teenager’s bedroom. Most physicists say that white holes are extremely unlikely to be real and their existence i
