It seems highly unlikely that USD will experience hyperinflation. And, if it does, to be honest, it'll be because the world economy is collapsing as a whole and no currency will be safe.

Are they offering their driver's license information as well? It does seem odd, unless it's some sort of bank thing. Banks now require ID before you can open an account, but, unless they're planning to use your ID to open an account (red flag!), they normally wouldn't need your DL info

I wouldn't call this a "life pro tip", but it reflects my basic life principle and I call it "hard agnosticism". It's easier to find holes in someone else's logic than to come up with a logical argument yourself. You can then generally conclude that, since there's no provably right or wrong answer, people should believe and act how they want. Ah, libertarianism!

I like potato-shaped :) because of the potato radius (https://www.technologyreview.com/2010/04/12/27697/potato-radius-to-define-dwarf-planets/). In the CSPICE computational libraries (https://naif.jpl.nasa.gov/naif/aboutspice.html), all bodies are modeled as "potatoes", or, formally, triaxial ellipsoids.

EDIT: the numbers I have say the triaxial diameters are 360.2 km × 266.0 km × 205.4 km

You're correct in thinking they are (almost) the same thing, but it's easier for average people (including people starting out in statistics) to think of "fair dice", "fair coin", "roulette wheel" or "what are the chances Ms Johnson has two boys..." versus something like "the discrete uniform distribution of {1, 2, 3, 4, 5, 6}" or "assume an independent binary process repeated 3 times..." or whatever.

So, why "(almost)"? Because, in the real world, there are no fair die, no fair coins (I believe a study recently showed that the way most people flip coins, the side that was up originally is more likely to be up after the flip), gender distribution at birth is unequal (more boys born than girls), and so on. There isn't even really such a thing as a random sample since we have no way to generate true randomness.

So, the whole coin/marbles/roulette wheel/etc thing is just a way to make statistics more accessible to the beginners and the average person

https://www.worldometers.info/oil/ says we have 47 years left, but it only counts proven oil reserves and excludes the possibility we will discover more oil.

A Venn diagram on https://www.nasdaq.com/articles/how-much-oil-left-earth-2017-12-27 isn't particularly helpful, but points out there's almost certainly more oil that we can obtain economically and even more that we can obtain but will probably be too expensive to be worthwhile

They're small but they're also fairly close to Earth. If you're talking about "iridium flares" (satellites visible briefly at certain locations) it's because all of the sunlight is being reflected onto a relatively small area of the Earth: https://en.wikipedia.org/wiki/Satellite_flare

I believe most satellites are still not visible to the naked eye most of the time.

Keep in mind that credit card debt can be negotiated and sometimes paid off for pennies on the dollar. In some cases, the credit card companies (banks) can end up paying you money if they violate debt collection practices. Always do debt negotiation through a lawyer since they will sue debt collection practices violators whereas companies that just do negotiation won't.

There was a time when you could invest in FOREX using credit cards (almost sure you can't any more), which gave you a little bit of arbitrage. If you invest in FOREX using credit cards and make money, great. If you lose money, you can pay it off for less than the total amount. You're basically gambling with someone else's money

All that is a long-winded way of saying: consider doing it with the understanding that, if your business fails, you can recover some or most of the cost by negotiating debt.

Of course, do NOT use home equity or any other form of collateralized debt for risky ventures

You're correct, but that's like talking about opportunity cost. For anything I choose to do today, there's a chance there's something I could've done something I'd enjoy more. That doesn't mean I've "lost enjoyment": it simply means I don't 100% optimize my life, which I don't think anyone does.

I agree with https://www.reddit.com/user/TyrconnellFL/ that you lose money only in a metaphorical sense. I doubt agencies like the FDIC would reimburse you for "losing money" due to inflation

Different people have different tolerances for risk. If you don't feel comfortable investing in instruments that can lose money, stick to bank accounts (but remember the FDIC limit on protection), Treasury instruments, or other money insured by the government, and hope our government doesn't collapse any time soon :)

We measure the distance to nearby stars using parallax: simplified, we take two points in the Earth's orbit that are 186 million miles apart and see how much a nearby star has shifted against the background of other stars. This amount, while measurable, is very small and not something you'd be able to see with the naked eye.

At 50,000mph, it'd take you about 6 months to get 186 million miles and you wouldn't see even a slight shift in the nearest stars (unless you had a telescope), so no, stars wouldn't whiz by at that speed.

Take heart, though. Thanks to relativity, you can crank up your speed to where you might actually notice changes in stellar angles, both because the galaxy is denser as you travel towards the center and because your "rapidity" (speed compensated for contraction) get quite high. More information:

This sounds suspicious. The idea behind hard pulls is that other potential lenders can see how much credit you're requesting at one time even if you haven't received the credit yet. For example, if you're requesting credit from 10 different banks at once, a bank would have no way of knowing how much credit they could extend you because they would have no way of knowing how much credit you already had (or would soon have) and thus your available credit to income ratio.

If it works, great, do it, and find other banks that do it and get as much credit as you can :) But, I'm guessing they'll say at some point "oh, I'm sorry but my boss says we have to do a hard pull-- is that ok?". It's also possible they want to pre-qualify you for an amount of credit with a soft pull and then do the hard pull once you formally apply
