Reply to comment by adamcoe in TIL that Milton Bradley originally had been in the business of selling pictures of celebrities. After his biggest seller Abraham Lincoln grew his iconic beard and rendered his entire stock of lithographs worthless and had customers demanding their money back, MB switched to selling board games by Loki-L

This is going to be a shocker to you, but people used to go to this place known as 'outside', to an area known as a 'venue', to see people on a thing called 'a stage'.

Reply to Today I learned that there is enough evidence to suggest that orca are actually an occasional predator of moose, due to the fact that moose can dive up to 20' for vegetation underwater in killer whale territories. by Uranusspinssideways

TLDR

There have been a few documented cases of killer whales attacking and killing moose that are swimming in bodies of water, It is believed that the orcas may mistake the moose for a type of marine mammal, such as a seal or sea lion, that they would typically hunt.

However, it's important to note that these incidents are quite rare and do not represent typical orca behavior.

Reply to comment by Auphor_Phaksache in TIL black holes also regurgitate matter such as stars that they suck in by Desolecontra

Particles are constantly appearing and annihilating, even in front of your face right now. It's called vacuum energy.

https://en.m.wikipedia.org/wiki/Vacuum_energy

>Vacuum energy can also be thought of in terms of virtual particles (also known as vacuum fluctuations) which are created and destroyed out of the vacuum. These particles are always created out of the vacuum in particle–antiparticle pairs, which in most cases shortly annihilate each other and disappear. However, these particles and antiparticles may interact with others before disappearing, a process which can be mapped using Feynman diagrams.

The process involving black holes is called hawking radiation.

Reply to comment by GarysCrispLettuce in TIL that artificial banana flavoring isn't based on a species of banana that got wiped out, but instead uses Isoamyl acetate to replicate the flavor, which is only part of what gives bananas their distinctive taste. by NoLackofEnthusiasm

That surprises me as artificial banana is one of the absolute worst of the artificial flavorings in my book--gaggingly horrible and nothing like a real banana at all.

Edit: Since it was covered in other comments--for the record, I prefer my bananas on the green side and once they are fully ripe, they are less than desirable but still edible. Once over-ripe they are downright nasty.

Reply to TIL of Macadam roads. These roads were convex, raised a few inches, and made of layered crushed rock; they were state-of-the-art for the 19th century. The rise of automobiles led to the dust issues that were solved by binding the roads with tar, leading to the invention of tarmac. by jamescookenotthatone

Indians still use them in rural areas, it's commonly known as kaccha rasta aka raw roads. They are quite reliable.. Water bound macadam roads
