That's interesting. Have you got a link to that youtuber?

Reply to ELI5: If the James Webb telescope is able to look 13.6 billion light years away, why aren't we looking at the surface of planets to search for life? by NolosRTX
Because planets are too small. James Webb is looking at crazy huge things. It's like trying to look at a grain of sand 50 miles away with binoculars.

Sorry, can I ask a sub-question that I think you can answer.
How did operator 'A' know the speed operator 'B' could read/understand?
I mean, by your example if one guy is firing 60 words a minute, how does he know he wasn't talking to 20 words per minute guy?
Ho about new guys? Were they all expected to understand 60 words per minute? If not... How would they tell the sender to slow down?

Stars and nebula are really big. If you can for example see a mountain that is 30 miles away with a telescope that doesn't mean that you can count the eyelashes of a person only a mile away. The mountain is so much bigger than the eyelashes that even at that distance it is much easier to see.
For example the Carina Nebula is 230 light years across, while a planet like Jupiter is 139,820 kilometers in diameter. So that is 139,820 kilometers across vs. 2,176,000,000,000,000 kilometers across. Even if the Carina Nebula is much more distant it can be easier to see than Jupiter.

Reply to ELI5: Why can we see differences between 60, 144, 165 and 240hz if the eye only can process 60fps? by Xyraph
The eye doesn't "process" in FPS. Instead, once a series of images reaches about 60 FPS, your brain stops interpreting them as individual images and instead interprets them as a continual "video. Above that, you can absolutely tell the difference in standardized framerates, but it's not as big as the difference in interpretation that happens at around 60 FPS.

Our retina retains images for about 1/10 of second. If images change faster, our brain sees it as a motion. 24 fps means that every image remains 1/24 of second on our retina, so giving motion illusion. The fastest the changes, the smoothest the motion.

It doesn't. It can reduce pain and local inflammation but your wound won't actually heal any faster. In fact, it'll make it take longer to heal as that inflammation is caused by an influx of cells that will do many beneficial and productive things such as killing any bacteria that may have entered the wound, digesting dead cells and making new blood vessels to restore nutrients to the area.

One possibility is that Newton's "indigo" was what we call blue, and his "blue" was what we call cyan.

Yes you can break with your engine. But I'm fairly certain you want to avoid that as you don't want to wear out your trans any faster than normal. Motors work in reverse when breaking and don't wear out as fast as breaking with your engine.

Healing time is affected. Healing time is increased as that annoying inflammation that you reduced is an essential stage of the Healing process.

Yup. If you look at a sound pattern of a native speaker speaking you can't usually tell the breaks between words. It is something of a continuous wave pattern. Our brain is doing the hard work of parsing into words.

It is so interesting what we have idiosyncrasies in. I remember playing soccer growing up and when i arrived at practice i could tell from the parking lot who was here from a distance awqy because i could recognize people's walks and runs before being close enough to make out their faces.
It's fascinating that that would even come across in the tiny, highly constrained motion of just tapping out code.

Reply to comment by _Connor in ELI5: When a bottle of whisky says 25 years, did they really make millions of gallons of that whisky 25 years ago? by wagmoo
They also don't only bottle 12 year whiskey.
The whiskey that they barrel this year, a portion of it will be bottled 12 years from now, a portion of it will be bottled 15 years from now, a portion of it 25 years from now, and so on.
They'll also barrel different portions in different types of barrels. So, of the 12 year whiskey, some will go in traditional oak barrels, but, if it's a larger production house, some in others types of cheaper barrels, and some will likely go in metal vats.
I assume that the ratio of those portions gets smaller and smaller as they get older. Like 50% of today's barrellage will get bottled in 12 years, another 30% will get bottled in 15, etc, to make whiskey more and more rare the longer it's aged. Plus, the longer you keep the whiskey in barrels, the more will evaporate.
All this plays into the price of the whiskey once it's on the shelves. With the metal-vatted whiskey being the cheapest because it won't have any taste, and because it will have evaporated the least.

The time it spent in the barrel. Once it's bottled, it doesn't age anymore.

Ohhhh gas giant just refers to then being composed of stuff that's normally a gas here on earth, it doesn't actually mean the planet has gaseous properties

During WWII my papa used to do that. He then taught us to use Morse code so we could keep secrets from my grandma . But he would do it so fast we would have to write out what we heard and figure out where one word ended and the next began.

You've got to remember that many distilleries are very old, some even hundreds of years old. So keeping batches for 12, 25 years etc is nothing in the long run. They know it will sell.
