If you launch something from the Earth, it will inherit the orbital speed from the Earth around the Sun, which is about 67000 mph. In order to make it fall into the Sun, you need to negate most of that speed.
Suppose you only give it a 1000 mph straight push towards the Sun, then the net speed will be 67007 mph, in a slightly different angle, leaving the junk in an elliptical orbit intersecting Earth orbit at the point where you pushed.
It just gets gradually worse until people have so little to lose that they'll start a revolution. Revolution leads to chaos, ultimately stabilizes with a strong leader, and then you get a series of leaders until you get one that's benevolent enough to increase rights to citizens.
Even though the story about the boots is fictional, there's a way out of that trap. You have to realize that you only need to buy a single pair of the good leather boots, to solve that particular problem for the rest of your life. After you get your first pair, you slowly save up the $50 for the next pair over the next 10 years. And then with the net money saved, you can get out of other traps.
The reason why people fail is because they cannot hold savings long enough to buy the expensive but durable goods. Instead, they'll spend their savings on something they don't need (as much).
McDonald's sells cheap food. This is the reason why, in America, "fresh food" is expensive.
I'm quite sure that people can cook a home meal for less than a McDonalds meal, especially if you have to drive there. Going to McDonalds is just less effort, and very tasty.
A crowbar dropped from orbit has a lot of kinetic energy
Orbital mechanics don't work that way. You cannot "drop" anything from orbit. And even if you manage to accelerate the crowbar enough to drop straight down, it would vaporize before it hit the ground.
Let's do another one then. It's an interesting experiment, no matter what. I vote for making it a bit more interesting too:
All equipment must be dropped in the desert, in mock rocket capsules. Crew must be working in full space suits whenever they are outside. No materials or equipment can be used except the things the crew brings with them. Nothing from the atmosphere can be used.
Or never used twitter for a conversation. I use twitter, but only to follow a couple of topics/people I'm interested in, and occasionally add a short comment. It's a good medium for that kind of stuff.
But the WHO says clearly that increased cancer is associated with all processed meats. If bacon was the culprit, they should have said that cancer is associated with bacon. Instead, they also mention stuff like corned beef and beef jerky.
Unfortunately the paper is paywalled but I think we can safely assume that they collected that data in order to control for it.
No, we cannot. What happens is the researchers collect a bunch of potentially confounding data, and then run it through a standard statistical package, typically the Cox proportional hazards model. https://en.wikipedia.org/wiki/...
The problem is that the Cox model only works if the confounders are linear, time-invariant, and independent. In practice, none of these requirements are met. In addition, not all possible confounders are collected, and they are also not measured accurately. People lie and they have bad memories.
Of course, the statistical calculations don't care if the input is bad, they just churn out some numbers. If the numbers say what the researcher (or their sponsor) wants to hear, they'll publish the results. Otherwise they can easily tweak some parameters and try again, or just throw away the whole study, and try a new one.
My guess is not much, given that by the 1960s the physics has been worked out pretty well and the materials have not changed markedly.
We have much better ways of 3D modelling, much better materials (like single crystal nickel alloys), and also much improved manufacturing techniques. The basic physics were known in the '60, but you couldn't model an entire rocket engine, because of wide scale interactions between pressure, temperature, intermediate reaction products, pressure wave propagation and deformation of the engine.
Also, some things may have been possible in the '60, like machining special alloys, or weird shapes, they have become much more practical and affordable now.
You'll find them in fruits and vegetables, sauces, fish, vegetable oils. The meats don't particulary stick out, except for salted fish (which I think it rarely mentioned when people talk about danger of processed meats).
We don't need that much iron and nickel that would require us to fuck up the whole crust or the atmosphere. Also, if you're going to invoke magical mining technology that you can get on 16 Psyche, we get to invoke magical mining technology that can cleanly extract metals from seawater, or a from a piece of useless desert.

How, explain. I wanna hear this

Where does it stop?

I would not trust a poop eating dog to give me culinary or nutritional advice, but to each their own I guess.

Well, that settles it then.
There are no barriers to better budgeting.

Looks like the dollar stores sell various kinds of canned goods. Nutrionally, there's not much difference between canned and fresh.

If you want hope, there are chemicals that will alter your brain.

It takes a lot more energy to throw it in the sun.
We need more robots in space, and less clowns. NASA needs to focus on real shit.
Nobody would build a plant remotely like this one, or situate a modern plant anywhere like there.
And was this the last unsafe plant in operation, or are there more plants at risk ? If there are more, what are the plans for shutting them down ?
...and it's too damn sultry in here.

I refer you to bacon.

Hmm.. when do you think we can get a better estimate on that planning ?
It can probably be tightened by drilling into the crater and doing isotope analysis. That's probably not NASA's cup of tea, though.

You mean the magical technology of picking up chunks of almost pure metal from the ground?
How much do you estimate we'd have to spend on rocket technology before we can ship, say, a billion tons of iron from 16 Psyche to Earth surface ?
How much do you think you could sell that iron for ?
Here's a list of different foods and their analysis of various kinds of nitrosamines.

I hear there's a bunch of excess carbon in the atmosphere.
