Reply to ELI5: When a third party app says they offer "end to end encryption," what does that mean? by [deleted]
Content is encrypted before it leaves your device, and is only decrypted when it reaches the other person's device. It has been encrypted from one end to the other.

Reply to Eli5: If we had steam powered trains back in the day, why didn’t steam become a common “clean” energy source? Why did it die out? by melatonin1212
You get steam by boiling water. How do you boil the water? That's the power source, not the steam.
The typical answer has been "burn coal to boil the water".

Reply to ELI5: if it's cheaper for stores to sell store branded same item why won't they fully/dramatically abandon name brands? by Then_Mountain_9893
People who insist on buying the name brands are willing to pay more for them, and will buy them even when store brands are available.
People who are willing to buy the store brand will buy it even if a more-expensive name brand is available.
By offering both name brand and store brand items, the store gets both of those people to come in and shop.

The 1st time you roll a 6 sided die, you have a 1/6 chance to roll a 6.
The 100th time you roll, you still have a 1/6 chance because it's still a 6-sided die.
The 100000000th time you roll, you still have a 1/6 chance to roll a 6 because it's still a 6-sided die.
If you have rolled four 6s in a row, then on the 5th roll you have a 1/6 chance to roll a 6, because it's still a 6-sided die. Completely apart from that, the chance of rolling five 6s in a row is 1/7776, because there are 7775 other possible combinations for those five rolls.

If you buy a house from someone, you give them money and they give you a house.
- If they still owe money on their mortgage, then they use your money to pay it off. If they have money left over then they made a profit. Hooray for them!
- If you took out a mortgage to afford the house, then you now owe the bank a whole lot of money. The house itself is the guarantee that you will pay them back: if you don't, they take the house.
- When you sell the house, the buyer will give you money. If you still owe money on your mortgage, then you will pay the bank. If you have money left, you have made a profit. Hooray for you!

Thus making the question self-answering, so I'm not sure what else there is to do.

Binary uses 2 digits because that's what "binary" means.
A system that used 3 digits would be trinary.

Make something heavier and it's tougher to move it.
The more mass something has, the harder it is to keep on making it go faster.
Anything with no mass moves as quickly as anything is able to move.

Reply to ELI5 why do your eyes adjust so fast to bright light but so slowly to darkness? by melig1991
Your pupils clamp down quickly because very bright light can damage your eyes. Kinda an "emergency lockdown" situation.
They can expand more slowly to be cautious of overdoing it.

Reply to comment by SpencerLoco in ELI5. Why is honey and lemon a popular cure for cold like symptoms. What makes lemon more effective than say an orange or lime? by alexkid_in_realworld
Pure honey is antibacterial because it sucks the water out of bacteria and kills them. Honey diluted into water is yummy bacterial food.

Reply to eli5. If Windows is an 11gb download, why do you need at least 65gbs free on your hard drive to run it? by graemo72
11 bags of groceries can fill 65 cabinet shelves once you unpack and sort them all. They're a lot more compact when they're all shoved into the grocery bags, but that's unusable - you need to unpack everything so it's easily available when you need it, even though it ends up taking up more space.

Reply to ELI5, why do viruses and bacteria have many of the same symptoms when they infect a human? by tapeness
The infections could cause all sorts of problems.
Your body's response will be fairly similar in many cases: "intruder alert, expel everything!" is a common one and covers sneezing, coughing, vomiting, and diarrhea, depending where the infection is. Likewise, your body sends a squad of white blood cells in full riot gear to the site of any infection - which then causes swelling as they flood the area.

Reply to ELI5: Why does MSG make food taste so irresistible? And why is everyone against it? by theinvincible-dosa
A baseless hysteria back in the 60s fueled by xenophobia lead to lots of people thinking that MSG is bad for you. Turns out the whole thing was total bullshit. The only people still against it are the ones who haven't gotten over the fake claims.
It's irresistible because it amps up savory flavors in anything.

Reply to ELI5: What is a nightshade? Why do we consider them different to other fruit/vegetables? by assignpseudonym
"Nightshade" is a huge family of plants that covers everything from tomatoes to potatoes. And belladonna too, commonly called "deadly nightshade".
The family as a whole is not considered to be different than other fruits or vegetable.
The general reasons why anyone would try to avoid anything are "medically diagnosed allergy", "self diagnosed allergy", or "fad diet that they got suckered in to".

Reply to eli5 - How can the human body be composed of 70% water when it feels and behaves like any other solid? by Virtual-Structure447
Take the amount of water that's inside a human body and just pour it all into a big bag. It sloshes around a lot and feels like a liquid, right? Your question is asking why people don't feel like that.
Well, take all of that water, and split it up among several billion teeny tiny boxes. Put all those boxes together in the shape of a human, and it'll contain the exact same amount of water as the big bag did, except now it'll feel solid because the water is all held within objects which have shape and structure.
In an actual human, those billions of teeny tiny boxes are all of the cells in the body.

Reply to ELI5 why is everybody saying that an 1.5°C increase in global temperature is catastrofic? by BloodyBite1
Global temperature - by definition - includes the entire globe.
The amount of energy it would take to increase the entire globe by 1.5°C is absolutely staggering.
Adding a mind-bogglingly large amount of energy to a system makes the system go crazy.
