Blocks of empty space within the known universe

AI Thread Summary
The discussion focuses on "blocks of empty space" in the universe, defined as areas devoid of matter and light. Participants clarify that while certain regions, like NGC 1999, appear empty, they may still contain minimal amounts of gas and light, indicating they are not completely void. The concept of these empty spaces is linked to observations made with advanced telescopes, which reveal that these areas are less dense compared to their surroundings. The conversation emphasizes the distinction between perceived emptiness and actual voids in space. Overall, the topic invites further exploration of the nature and significance of these regions in the universe.

Please share the information you have about this topic, post only valid articles and research.

By "blocks of empty space within the known universe" I mean blocks of space that are free of both matter and light i.e. there is no light or matter within that space;empty and dark. And the known universe to be the space from which we still receive light.

Those links refer to a "hole" in a cloud of dust. That doesn't imply that it is literrally completely void of all things, including dust and gas and light, but merely that it is a sudden dropoff of density in the middle of the cloud. There is still light and small amounts of gas inside the hole.

... Aided by the ground-based Mayall (Kitt Peak) and Magellan telescopes, it was determined that the patch looks black not because it is an extremely dense pocket of gas, but because it is truly empty...

Thats from Wikipedia NGC 1999. There might be something but it should be insignificant.

Yep. There is still something there, but not alot. At least compared to the cloud surrounding it.

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
