Explanation: Sure, you can see the 2D rectangle of colors, but can you see deeper? Counting color patches in the featured image, you might estimate that the most information that this 2D digital image can hold is about 60 (horizontal) x 50(vertical) x 256 (possible colors) = 768,000 bits. However, the yet-unproven Holographic Principle states that, counter-intuitively, the information in a 2D panel can include all of the information in a 3D room that can be enclosed by the panel. The principle derives from the idea that the Planck length, the length scale where quantum mechanics begins to dominate classical gravity, is one side of an area that can hold only about one bit of information. The limit was first postulated by physicist Gerard 't Hooft in 1993. It can arise from generalizations from seemingly distant speculation that the information held by a black hole is determined not by its enclosed volume but by the surface area of its event horizon. The term "holographic" arises from a hologram analogy where three-dimension images are created by projecting light through a flat screen. Beware, some people staring at the featured image may not think it encodes just 768,000 bits -- nor even 2563,000 bit permutations -- rather they might claim it encodes a three-dimensional teapot.
For more detail go to the link and click on the image for a high definition image. You can then move the magnifying glass cursor then click to zoom in and click again to zoom out. When zoomed in you can scan by moving the side bars on the bottom and right side of the image.
It looks like a cheeseburger surrounded by multi-colored french fries.
I got nothing.
It is strange sometimes what qualifies as an “astronomy picture” to NASA...
same...
should change the name to Astronomy wmmft of the Day...
Only one of those things I ever got was the Hardees star in their TV ad.
Use a tablet, not a computer. Hold it close to your nose. Relax your eyes and focus on something far away at the horizon (while still looking at the screen). Slowly move the screen away from your nose while keeping your eyes focused far away. Do not shift your eye focus to the screen. You may have to repeat this a few times, but once, suddenly, you will see the 3D teapot.
These were popular about 20 years ago.
A Jackson Pollock star map?
Once you get it, you can make the teapot pretty much appear on demand while holding the tablet about 8” to 10” off your nose. It will suddenly pop into view.
These “holographic” images are really weird.
That’s one ugly teapot.
I see a row of drunk penguins slouching toward Skid Row.
Neatest one that I’ve seen.
You have to learn to focus past the picture.
IOW as if the picture were further out from where it actually is.
I see Yoda’s head on the top plane and an intesecting plane coming in at an angle just below his head. Damn my LSD just wore off. Can’t see anything but colored wigglies now.
Some strange stuff going on in the brain to enable you to see that.
I haven't wrapped my head around the holographic description, but this math is just sloppy. If there are 256 possible colors per pixel, then you only have 8 bits per pixel not 256. Thus the math is 60 x 50 x 8 = 24,000 bits.
The tea pot is filled with Ovaltine.
Took me a while to see the teapot. You actually have to focus past the picture.
