Okay so I was watching The I.T. Crowd and there was a sticker that on the door that says “MP3 is not a crime” and I looked it up and I couldn’t really understand anything I was reading (maybe it’s been a long day).

The articles reference something called Napster, legal battles, consumer rights in music media, MP3s (remember those?), MUSIC (the organization, ig?), and I couldn’t understand much of the words or the situation.

Anyways, would love a simplified explanation because it does seem fairly interesting and, from what I did pick up, something relevant as video game companies stop making physical copies of games so that no one really “owns” what they buy.

Title basically, i just watched interstellar for the first time yesterday, and while i can understand the theory itself, i don’t understand how the biological time changes. For example, lets say i’m someone in space where 1 hour there is 10 years on earth, my organs would age 1 hour yet on earth for someone they will age 10 years? Like are organs, cells, our body bounded to a “general/universal” time where they age almost at the same rate for all humans but somehow differ when in different places of space or what?

Sorry if i’m not making it clear but this has been something i always thought about ever since i heard of the theory lol

Im really intrigued by this because like with diabetes they at least had some idea of what was going on. Like when they discovered insulin they had some idea that the pancreas was malfunctioning.

We can do surgery on the spine and brain, so why can't we get the samples needed to test while the person or animal is alive? I know it would not make financial sense to do this for every stray dog that bites someone instead of the tradional method of testing but if someone is willing to pay for the animal/person to be tested, why can't we do that?

Wouldn't the speed limit of C be cancelled out if gravity was in a perfect contradictory force from the incoming light?

And is it real?

To this day, I cannot grasp the explanation. Please give me the analogy that allows both to be true.

i think the person was asking about the xray tunnel where the cary ons are scanned

So if West Point is described as The United States Military Academy (aka the official military academy for the United States) how do graduates of places like The Citadel, VMI or Norwich get their commissions?

I recently watched a video where a woman put a bunch of raw chicken into mason jars and put them in her canner (some kind of huge crockpot looking thing). I simply cannot wrap my mind around the idea that you can “can” something that would usually be bad in about a week in the fridge, but because it is “canned”, it can be shelf stable, out of the fridge, for years. I know this is a practice that has been around for ages. My father grew up canning food. I just want to understand the science behind it. How does it not go bad? Is this because it is airtight? Help me understand!!

Are they more likely to do so in-flight?

i just blew an ant off my table, does it die when it hits the ground? (i dont know where the ant went).

if i throw a non flyable bug off the 20th floor, will it die? if not, how does it survive??? ELI5 please :,)

I know that this is something I can google in theory, but I have tried, and still never quite get it. I had a few friends when I was in elementary school who had jailbroken iPod touches (around ios7 > time and usually by older siblings), and tried to learn but couldn't. I guess I am curious what you are actually doing to the technology to add these things!

ELI5 and am pretty clueless about technology lol :P

I know taste and smell are linked but why does food sometimes smell better than it tastes? Or some foods in general?

I understand UV can cause brittleness but what about plastic that isn't exposed to UV?

I was just thinking about the Artemis 2 mission, and I remember the heat shield was being talked about a lot, because it didn’t work as planned on Artemis 1. I googled why they needed a heat shield, and it sounds like it is because the air was being compressed so hard, it created heat. I don’t understand how that works, so I would love to know. Thanks in advance!!

If you take nothing out of something, you can do it infinite times, so why is it undefined and not infinity?
