When I was a young man, I became deeply fascinated with black holes. I’d lie in my bed at night and try to imagine what it would feel like to enter one.
How did you imagine it?
With my mind.
Do you normally let other people use your mind to imagine things?
Yeah, but they always leave it a mess
What do you charge per hour of brain use?
About 3 fiddy
Do you accept schmeckles?
But that is a simulated image
I hate to break it to you, but every photograph you’ve ever seen is a simulated image.
It’s a new color every time
it’s a false color image
it’s too tiny to take a picture of using a traditional telescope, so instead, they use multiple telescopes around the Earth, and piecemeal that data together. Which means they have to reconstruct the missing details (it’s not made up, it’s more like playing “connect the dots” with tons of math)
the final image is a composite of 3 different grayscale images, taken at different wavelengths of light.
The resulting black and white images are given different colors, then blended together (which is pretty similar to how cameras take images, they just map the grayscale images to colors we can see with our eyes)
