Black Holes - Try This!
Black Holes
Imagine this!
A black hole is nothing more than the extreme limit of gravity. Tt's a very large collection of matter taking up a very small space.
Think of it this way. Einstein showed us that all matter curves space, right? Well, because it's so hard to visualize this curvature (because space-time occupies the accursed 4th dimension with width, height, length, and time) scientists have come up with an easy way to think about it.
Imagine space as being only 2 dimensional... like a piece of paper or a sheet of plastic. Then, with nothing in it, the space would be flat, like this:
Try this!
Look at the images below of objects in our Universe positioned in space-time. Choose the image that best represents the result of a) our Earth, b) the Sun, c) a white dwarf, d) a neutron star, and e) a black hole as it would appear making a "dent" in space-time.
