Ok so black holes are just teleporters to other dimensions right?!
It's a one way teleporter to a single dimension, because you're entire mass will be a single imperceptible point.
But it's not a single point though, because blackholes with a different mass have different sizes, so it's more like a "maximum density" that can exist in this universe...
It's an oversimplification, but something with the mass of say, a human, will be crushed into a very very very very tiny space. A much smaller space than 0.1mm radius, which would hold Earth's moon's mass of 7.342×10^22 kg.
Yes... And something with the mass of the universe will crush into a significantly larger (yet comparatively tiny) volume of space... Thus, a black hole is basically the maximum density we can currently comprehend and theorize.
Size and density have non-standard definitions in this context.
As far as i know the Mass of the black Hole is concentrated in the Center (singularity). But it is surouded by its schwarzschild Radius. Anything that enters it cant escape.
Well, unless it burps
Time slows down as the mass approaches the center, so it just can never reach it. It’s stuck in time dilation approaching infinity.
That's what the current understanding of physics says. But given that there are singularities that come out of the math, all that really means is we don't actually know what happens inside a black hole.
Kind of like the lump that forms in my chest when I get a phone call
I equate it to a can of spray cheese. Small hole, puffy cheese.
I thought you were making this up, but apparently there actually is "cheese" that comes in a spray bottle.
What the wiki article does not explain, is why.
Some people put it on crackers but when I was growing up we always put it in the bugles chips.
That is also why I always thought people who pretended to have witch nails by wearing bugles were weird, I was always like “why would you put cheese all over your fingers…”.
Maybe it's just because I'm still shocked at the existence of this product, but I don't see why either of those use cases need cheese in a can instead of just cheese.
Partly it's convenience, but I think the main reason is you can get cheddar and bacon flavored spray cheese.
Real cheese takes a couple seconds to scoop or even slice. The can is as simple as flexing your finger, and an endless stream of “cheese” comes out!
Dogs are big fans as well.
They used to take them on dive trips and squirt it in the water and the fish would eat it. Some diver masters would play jokes and squirt it in other divers hair and the fish would start eating at their hair.
EASY CHEEEEESE!
There's a place in Philly that uses it as the cheese for their steak subs.
It's wrong, but they still do for some reason.
Wrong to whom? It’s the same thing as Cheez Whiz, which is the right cheese.
“Cheese”
Cheese flavoured foam extrusion
Bruh ez cheese on a Ritz or club cracker. If ur brain doesn't go nuts for that u don't have a single taste bud.
I don't know what it tastes like, but it looks like American cheese.
Is the flavour different from say, cheese whiz, a plastic cheese slice, or an unspiced queso?
It isn't spicy like cheese whiz. Have you ever had the little keebler lunch packs of crackers and cheese? They're like that. Flavor is close to a plastic cheese single I guess so yeah American cheese but the texture is different. If you can ever get a can I highly recommend it just for the fun of it.
It'll teleport you from the third dimension to the first dimension.
