Posterity comes from Middle English posterite, from Anglo-French pusterite, from Latin posterus ("coming after")
This month we talked about a lot of things Space related. From the Apollo and Artemis Missions to the moon and stars! Since it's almost Halloween, we wanted to end the month with one of the universe's most mysterious objects, Black Holes.
According to Sciencenewsforstudents.org,
"A black hole isn’t really a hole. It’s an object in space with incredible mass packed into a very small area. All that mass creates such a huge gravitational tug that nothing can escape a black hole, including light."
Though Albert Einstein first predicted these massive entities in the early 1900's using his general theory of relativity, it was not until 1976 that a name for them appeared. Since then, there has been a lot of talk and research about black holes, but no one has seen one until now. Check out this image release by The Even Horizon Telescope Project!
The Event Horizon Telescope Project got this image by using a global system of ground-based radio telescopes and combining their findings. We are now able to see what a black hole actually looks like!

To understand Black Holes we have to make sure our children understand Gravity!
Let's get the definition from Nasa:
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
By this definition, objects that have more mass have more gravity!
