Would they sky be scorched? Ash everywhere? No oxygen? Battery acid oceans? How long would such nuclear winter last? How would Earth look from space? Months later, if ISS astronauts had to land for supplies, could they?

I ask this because I'm developing a story idea. If you could, please describe what nuclear winter would be like? How alien would it be?

What kind of thermometer would I need to buy to measure liquids such as water, milk, and soup?
I have to do a science fair project and don't know if I need a specific kind.
Could you also let me know where I would be able to buy this kind of thermometer? Thanks to everyone in advance!

Why, when you turn off a lightbulb, does the light currently in the room go away? The photons are still there, bouncing around, but they don't act the same as when the light is on. Shouldn't you see the photons still moving around reflecting off of surfaces and reaching your eyes? Yes, they can leak out in various places in the room, but say you have a perfectly sealed box of mirrors with a lightbulb inside. When you turn that light off, where do the photons go? They don't go throught the mirrors; then the box would glow, they don't dissapear; impossible, and they don't stick around; the inside of the box would be perpetually light. I want real, supportive answers based on scientific fact.

This is just another moment in which I have been given the ability to question the most simple concepts. (this is where your laugh may be inserted) So beside the question of “which came first, the chicken or the egg?” ha ha. I have honestly thought of another just as interesting question: If in our evolution we started with one male and one female(regardless of if it was in human form, monkey, dinosaur, etc) then the following is a run down of what would of happened(as sick as it may seem)

Male has sex with female to produce a child.
Now that child has to either have sex with parent OR wait for the parents to have another child of the opposing sex so that they can have sex together, gosh this all sound like a bunch of incest! But then how else may we have evolved?

seems like a waste of good sunlight and heat to not be trying to harness some of it right now. think of how much energy we could be getting from there. i know it would cost too much and would probably take more energy to set it up and go get the energy than it will provide, but should we be brainstorming right now how to overcome these inproficiencies? << wow what a word.

There is a fence with squiggly metal wire. If I look at the skyline
(approx. 3-4 miles away), the buildings appear bent in more than
one place.

Why is this? How does this work? P.S. It only works during the
daytime.

in this experiment it shows how an atom can show both characteristics of both a wave and a particle, why is it a big deal when they place a detector next to one of the slits and it calapses the wave function to a particle, i know how its weird when it does that but they are saying stuff like its the conscience mind controling the function of the atom, dont they know that when you try to detect or observe something it causes interferance with the wave, can somebody please explain why they are thinking its the conscience mind and not the detector that is causing it to turn into a particle
