We have a pretty good idea of how and when the universe began as for how it’s going to end, hmm?
Astronomers have been eyeing the Eta Carinae, a huge star weighing 120 times that of the Sun and is dubbed as the “Death Star,” for many years. Social media sectors are alarmed with the fact that the flare that would be generated by the collapse of Eta Carinae could end life on Earth. It is said that the flare would be 100 times bigger than the Earth and could produce a radiation enough to kill all the people in the world.
Christopher Nolan’s Interstellar raises a few questions about the possibility of wormhole travel. If Earth were to ever come to shambles, would the solution be to teleport to another planet via a double-ended tunnel – essentially a short cut though space?
It’s easy to guess where the hottest place in the universe might be — the core of a giant star, maybe, or a disk of gas heated to millions of degrees as it tries to cram its way into a super-massive black hole, or even, for a fraction of a second, a fusion reactor in New Jersey. It’s harder to imagine the coldest place, though.
Anyone of us wondered at least once in his lifetime, exactly where is the coldest place on the planet. Either we put this question in a blizzard and cold evening winter, or simply because we are curious to know more about world in which we live, there are places on our planet where the temperature drops to almost unimaginable levels.
