For example the Variant Creutzfeldt Jakob Disease

If doctors say a surgery has a 1% chance of causing death, does that literally mean that if 100 people undergo the same surgery, 1 person would be expected to die and the other 99 would survive?

Does that percentage apply to every specific person, if that's the case wouldn't that mean, theoretically, every healthy person should survive out of the 100 people since every person has a 99% chance of not dying?

I've been seeing people talk about these things called "liminal spaces" lately mostly on posts with weird looking pictures of empty places. I don't really know much about them but I'm kinda curious. What exactly makes a place liminal?

I’m not referring to people that are say 350 pounds. I’m more referring to the super obese people that are in the 900+ pound range.

What is the benefit of having the cell body in different locations? What factors do neurons used to communicate with each other so that they can for complex circuits, and what determines if a neuron is stimulatory or inhibitory?

Is it possible to turn our chemical energy (whatever makes us able to move, carry heavy loads, ect.) Into some kind of matter?

I've only ever seen people use bombs as examples but I was wondering if it would be possible to turn that energy into a non explosive material.

I wouldn’t try the water in the latter, but that has been the result of my unintentional experiments: months-long-left water container just looking intact.

Recapped plastic soda bottles seemingly free of mold for weeks too - are they still not safe, or do molds originally grow faster than from merely moist?

like, I know what a zero is, and also what a function is sometimes even how to calculate them, bo idea of the difference between a trivial zero and a non trivial one

That is my question. Saw a pretty good documentary about the universe and dark matter and dark energy, but it never explained that bit.

I’ve always wondered how it can be the exact same temperature on paper, but feel completely different depending on the weather.

Like, 15°C can feel freezing when it’s windy, weirdly warm when the sun is out, or uncomfortable when it’s humid.

What’s actually happening to our bodies that makes the same temperature feel so different? Is it mostly about how quickly we lose heat, or are there other factors involved?

I've read enough to know that "cold-turkey" for alcoholics can be lethal, upto and including seizures and a host of other side effects and symptoms but I don't really understand the "why"? What is it about alcohol dependency and our biology that causes it to be so dangerous?

Squid seem to be indifferent to the water pressure wherever they go, they have even been known to sometimes drag pray down into the depths as to turn them unconscious.

I read here that it has to do with having waterfilled bodies, but fish also have completely water filled bodies(?)

Connecting two other ELI5s. This is something that I've always struggled with.

Space is nothing. There is no actual "fabric" of space. There are things in space, and the "space" in between is.. nothing.

Nothing, as I understand it, is without mass, energy, information, anything. There is no thing to bend.

But! Gravity doesn't bend light because light doesn't have mass. It bends space and we see light bend along it.

How can nothingness be bent?

And why doesn't light just pass through empty nothingness on the same trajectory, if it isn't being acted on by gravity? OR is it that it does do this and it's only our 3D perception that it has changed trajectory?

When we talk about gravity bending space, are we actually talking about the distribution of Stuff within a given area, as it relates to another body, due to the effect of gravity? e.g. the distribution of Stuff around a random planet

I know this is very long and contains multiple questions. My hope is that by including all of this, it will make clear where my misunderstanding is. The real question is, how can nothing be bent?

Sand is solid and you can’t see through it at all. But when you melt sand down and turn it into glass, light passes right through it. What actually changes at the atomic level during melting that makes light suddenly go through instead of bouncing off?

As, in between us and other bodies like the moon and the sun? What is in between? What is the "fabric" of the universe?
