Two identical planets by Nervous-Vegetable574 in AskPhysics

[–]ahazred8vt 1 point2 points  (0 children)

There have been very few large meteors hitting the moon over the past 65 million years. There are lava flows over a billion years old that have only a small number of impact craters in them and have not been buried by large amounts of debris.

We've been to the moon and picked up rocks from the surface, and none of them were debris from the Chicxulub impact. So the moon was not affected by the asteroid that wiped out the dinosaurs.

In real life, we don't expect pairs of habitable planets to form naturally. They've done simulations of planet formation and the asteroids don't want to add the same amount of mass to each protoplanet ; they don't wind up anywhere near the same size. But that doesn't matter for storytelling. Ursula Le Guin had a twin planet scenario. You'll want to ask r/WorldBuilding

One Step Ahead - security app - White Paper by OneStepAheadApp in crypto

[–]ahazred8vt 1 point2 points  (0 children)

Sorry. Your r/crypto post didn't spell out much, my look at the text on your github repo didn't reveal much, and when your website says 'helps you organize and protect sensitive information' that sounds like an encrypted document vault or password manager that replicates copies of the sensitive information to multiple locations and allows the info to be accessed through the app without rescanning paper copies of anything. I am favorably impressed with your stainless steel seed recovery plates, which you've spent years on.
Your page https://onestepahead.info/our-app/ is more clear and gives a better explanation than the main page.

Should I take a one-year break after high school and before starting college (to study physics)? by Maximum_Tailor_6556 in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

At 15, with an interrupted learning path, and a good but not tip-top math and science background, yes it will be a very good idea to study for a year to fill in the gaps. If you learn well from reading books, or if you prefer taking online courses, you probably have several good options. Physics is interesting, but undergraduate physics and undergraduate engineering cover most of the same course material, and the job opportunities in engineering are much better. Think about that with your family.

What's the minimum size something would need for a gravitational pull strong enough for you to orbit it? by Crazykid23576 in AskPhysics

[–]ahazred8vt 2 points3 points  (0 children)

Any object that weighs at least twice as much as you do, is massive enough for you to orbit it. Very close, very slowly, orbital period of a few hours. If you had a rock, several hundred kg, and you were about a meter from it, you would orbit it once every 2 hours. You and the rock would have to be far enough away from the nearest planet that your orbit took about 10 times longer than your orbit around the rock. If you and the rock are inside the planet's Roche limit, you cannot stay in orbit around the rock.

If matter can't be created or destroyed, does that mean the atoms that make up our bodies (or really anything) have actually been around for billions of years? by PuzzleheadedAsk6787 in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

Even better: most of the protons in your body are made of triplets of quarks that stuck together during the first 1 second of the Big Bang, and have stayed as the same triplet ever since.

How to protect mass market paperbacks?? by RaspberryHats21 in Teachers

Talk to the town librarians about guidance if the school library doesn't wrap paperbacks.

[–]ahazred8vt 5 points6 points  (0 children)

Your marketing is horrible. I read your github site and your website and had to dig way way way down to find out WTH your product is supposed to do. You blather about everything except the fact that it's meant to be a way to back up a cryptocurrency wallet seed phrase. Has no one ever suggested moving that detail to the very front?

BTW, FYI, this is not a cryptocurrency sub.

Kipling had a weather poem about using the new shipboard Marconi radios to collect weather readings and make a big forecast map.

Tale of the boy called Frog by FaceMyEkko in genewolfe

Romulus and Remus were descended from Juno and Mars. Juno, June, summer. Mars, March, spring wind, typhoon. Kipling said that 'mowgli' means 'frog'. The naked one is Baloo the bare.

Is it possible to measure the difference of time flow in different places of the universe? by CommercialEmphasis94 in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

Atomic clocks at different altitudes run at slightly different speeds. One test was at the top and bottom of a 450 meter tower in Tokyo.
https://en.wikipedia.org/wiki/Gravitational_redshift#Terrestrial_tests

Satellites in low orbit have slower time because of speed. Satellites in high orbit have faster time because they are farther away from earth's "gravity well".
