2. There’s a Monster Black Hole At the Center Of Our Galaxy
With the common knowledge that our galaxy is enormous, you must have a little fear lingering around in your mind about what’s out there, right? How about a black hole to start? The black hole at the center of our galaxy is quite impressive, with an estimated mass that is billions of times more massive than our sun. It may have started considerably smaller, but our universe has an abundant supply of gas and dust that has let the black hole grow to an impressive size.
How do scientists know there is a black hole in the middle of the galaxy? While black holes can’t currently be observed directly, astronomers can detect their presence and estimate their size based on the gravitational effects that can be viewed around them. It is now believed that most galaxies have a black hole at their center. Does that mean we should be less worried about the black hole causing damage to the planets in the solar system? Sure, why not.
