Weirdo types that decided they were in charge of naming things decided to name it Aluminium so it “matched” the likes of other metals like titanium, iridium, etc
That’s not how acronym pronunciation works though. We don’t pronounce them based on the words they stand for, otherwise we would pronounce NASA, SCUBA, LASER, etc. differently. Both pronunciations have valid arguments so why can’t we just accept both and stop being weird about it.
And they tell you to get whiskey or rum, not Coors.
Or a Coors. Who cares. It’s alcohol.
Also how many whys does it take to get to the big bang and final we can’t know before popping we need better instruments or math so difficult it’s impossible for even mathematicians to pretend to make sense of besides ‘maybe, the math works anyway.’
So are polar bears considered more dangerous and aggro than grizzlies? I mean it wouldn’t be too crazy, particularly since it’s probably rare to encounter one, compare to grizzlies. But just had never really heard that.
Gotcha so the idea is they’re just gonna give it a shot and try to eat you, regardless, because the stakes, they are high?
To be fair, in a moral sense, they should absolutely try and eat every human they can get their claws on; we have done a bang up job on making their habitat and food sources disappear.
Their habitat has also shrunk so much, and their population dwindled so much, that they have gotten fairly inbred and that is causing more aggression and insanity.
There is also a female polar that keeps breeding with grizzlies, and those offspring are consistently more aggressive and dangerous.
Polar bears, because of their location, see everything as food. Black bears and grizzlies, while omnivores, are more specific.
And I feel like I have to say this to counter this weird perception online: black bears and grizzlies do not hunt humans. They generally don’t like humans and will stay away. But carry bear spray.
Someone correct me if I’m missing some nuance here, but heat doesn’t get transferred directly through space because heat is vibrating molecules and space is a vacuum. The sun radiates (speed O’ light). A lot of that radiation just reflects off the earth (or we wouldn’t be able to see it), but a lot of it gets absorbed. THAT’s when it’s converted into heat energy. It’s also why the greenhouse effect is a global phenomena: light energy comes in across the vacuum relatively easily, turns to heat on Earth instead of being reflected, heat energy cannot escape as easily as light energy.
Any visible planet or asteroid would. So some stars would also appear to blink out, but those would take longer to blink out. So the moon would go after 8 minutes, Jupiter would take 43 minutes to stop receiving light, and another 35-52 minutes to disappear for earth depending on orbital locations.
Presumably we would get something on radio/tv/internet from the side facing the sun once they realized it, that of course being only if they hadn’t already been eradicated by a horrific shockwave caused by whatever event caused the sun to vanish before they had a chance to report what they saw, because supernovae tend to travel at very close to the speed of light, so there wouldn’t be much time for them to react.
And if this is a supernova, you might just have time to grok what happened before the planet was obliterated under your feet from the shockwave.
So I guess… chances are we would just barely understand what happened before we were gone.
It takes 8 minutes for the light to travel from the sun to Earth. Because light in a vacuum travels faster than anything, including information, we would not and could not know it had disappeared for 8 minutes. This means Earth would continue to follow its orbit around a non-existent sun for 8 minutes because the Sun’s gravity would still be acting on the Earth.
If it was nighttime, you wouldn’t notice the sudden lack of sunlight (other than if it was a full moon) but you’d almost certainly notice the change in gravity.
Edit: actually, you wouldn’t feel any difference in gravity or experience any change of acceleration. What you would experience is a very tiny vibration, of 1 million push notifications being sent to your phone from the other side of the planet.
Yes, gravity is believed to travel at the speed of light.
According to Einstein’s theory of general relativity, the effects of gravity propagate through spacetime at the speed of light. This means that if a massive object were to suddenly change its position, the gravitational effects would not be felt instantaneously by objects around it, but would instead spread outward at the speed of light.
This is in contrast to the classical Newtonian view of gravity, which treated it as an instantaneous force. Einstein’s theory showed that gravity, like other forms of electromagnetic radiation, obeys the speed limit set by the speed of light.
Experimental evidence, such as observations of binary pulsars, has confirmed that gravity does indeed propagate at the speed of light, as predicted by general relativity. This is a crucial aspect of our modern understanding of the nature of gravity and its relationship to the fabric of spacetime.
you’d almost certainly notice the change in gravity.
Really? can you actually percieve the sun gravity? Do you mean that we would get like a tsunami beause of the tidal effect? Now I kinda want a documentary about this.
I don’t think you’d actually “notice” the gravity.
Earth would still retain it’s mass, and we’re much closer to it, so it’s lesser mass acts much more on us than the sun’s greater.
Though, the earth would stop orbiting the sun and travel on a mostly tangential path travel nearly radially away from where the sun was, instead of the elliptical path it currently travels.
This is a very interesting physics question that I may look into further. Specifically what would the theoretical acceleration be, due to the lack of the sun? Is it above a humans level of perception?
It’s weird to say that light travels faster than information, because light is information. In other words, top speed for information IS speed of light.
Which two event are you talking about being simultaneous? The Sun going out and Earthers observing it? Those things will not be simultaneous in any reference frame, because they are “light-like” separated. (ie they lie on a 45 degree line in a Minkowski plot.)
Team aluminum all the way. A higher up where I work is obsessed with stainless steel, he gets these monstrous heavy duty tables made out of SS that hold objects 1/3 of their weight. Makes lab rearranging a nightmare lol.
If you really want to stop the stainless steel obsession, you could start cleaning the benches with bleach and not rinsing again afterwards. The corrosion will set in quickly.
Aluminum is where it’s at, and where it is, is everywhere.
Your cans? Aluminum. Your car? Mostly aluminum. Old wiring, you better believe that’s aluminum. Your fucking phone screen is aluminum, sand paper is aluminum, half the birth stones are all aluminum let’s fucking goooo baybee
