Location:Gliese 436 Star System, Leo Constellation
Have you ever put your hand under super-hot water and your hand originally was cold until you experienced the burn? What about a warm feeling before touching something bitterly cold? This is not just something humans experience, as it can (sort of) happen to planets too. The Gliese 436b planet is certainly a paradox for astronomers. This exoplanet is almost exclusively made from ice. Yet somehow, it is also on fire.
On the surface of the planet, the temperature reaches 822 degrees Fahrenheit (439 degrees Celsius). In spite of this, the planet maintains its icy landscape, remaining completely frozen. How does it accomplish this? At first, scientists did not know but eventually, they found that the immense gravitational force exerted by the planet’s core was the cause. This force makes ice much denser, allowing it to handle high levels of heat. It even compresses water vapor that might normally evaporate.
We all know by now that black holes suck up everything around them. While it might appear to those watching that something is moving into the black hole at a snail-slow pace, it is long gone. This is quite interesting because as a black hole absorbs things, most assume it can only absorb so much before it must spit stuff out. This is why many assumed for years that black holes might open up elsewhere. The proposal that something like this had to be the case comes from Igor Novikov.
In 1964, the Russian Physicist used Einstein’s field equations to come to his conclusion. He coined the “white hole” theory, which proposed that, unlike a black hole that uses gravity to suck things up, white holes use gravity to push things away. Which made many assume that the white hole spits out things a black hole absorbed. NASA has come across things that appeared like white holes. While they might not operate exactly as we assumed, it appears to be at least possible.
