Calling all astrophiles!
You’ll be sure to excite the astrophiles, budding astronomers and scientists in your class by including spacey facts and far-out lessons about black holes.
Your students will be mesmerized by such mind-bending facts like
- A black hole is not really a hole at all! It’s an enormously dense object. Anything falls into can never escape. Never!
- Our Milky Way galaxy has a black hole (4 million times the Sun’s mass)! However, it’s light years away from earth, so we’re safe for now.
- Based on Einstein’s theory of general relativity, if someone fell into a black hole, time would slow down for them relative to an outside observer. But slowed time would be the least of their worries, considering the black hole’s extreme gravitational force.
- The first black hole imaged by researchers was found in the M87 galaxy (55 million light-years away) and is 6.5 billion times the Sun’s mass.1
These are mind-boggling facts for sure! But, with your help, students can stretch their minds and understand the gravity of the black hole phenomenon.
