You're correct, but hypersonic is an important term because there's different design considerations for machines that operate near and above the sound barrier, usually they commonly broken into transonic, supersonic, and hypersonic, used in aerospace industry and science. My physics master's degree is in compressible fluid dynamics. With supersonic, you want something that pierces the air like the Concord, with hypersonic, you want something that is more blunt and can withstand the heat (think space shuttle or space re-entry capsule)
China is definitely the leader in hypersonic anti-ship missiles, Russia is second. Also Russia/USSR was a major leader in supercavitating torpedos launched from submarines, probably still the leader today. All-in-all, it doesn't matter too much who's in the lead, the very existence of these technologies makes all surface navy ships nothing more than targets to be sunk within hours, the asymmetry between offensive and defensive capabilities is extreme.
If you really want to know what the US so-called experts admit to when it comes to US vs China capabilities, the best things to read are the "national defense strategy" the "DoD budget request" and the actually budget bill, known as the NDAA, that's where they admit that China is ahead in many technologies, or that the US has no way to defend against them.
Unfortunately, more toxic than that. Green potatoes contain high amounts of solanine,; its toxic. I can't eat potatoes because I've had solanine poisoning from eating green potatoes and now any amount of potato skin triggers hives.
I can't think of a worse way to prepare food. More than half that food is going to waste, so nasty and disgusting. I'm going to invent a time machine, find the mother of the person who came up wtih seafood boil, and teach her to teach her child not to play with his food.
Then I'm going to do something more productive with that food, like not mix it with animals from the sea.
I'd build the world's first international spaceport. If it was USA, I'd build it up the side of the Hawaii volcano. The goal is to get it as high as possible, as close to equator as possible, to take advantage of earth's angular velocity. If possible, building in the Andes would be even better.
Humanity has to cut the cost of space launches by 99% or more if we are ever going to advance to the next phase of history: Mining the asteroid belt for necessary minerals. All progress comes from raw materials in some capacity and the asteroid belt is a near unlimited source.
The US will blow a trillion dollars on a failed F-35 program, but won't even build up its own semiconductor manufacturing industry. The US truly is fucked.
America won WWII through recycling model Ts and other crap we had laying around in landfills and turning it into ships planes and tanks. We shipp all our scrap to other countries these days, there is no reserve to quickly ramp up new production lines. In fact, China built some of their infrastructure on the bones of American waste, even including the scrap we sent over from the world trade center and the solar panels that Carter put on the white house. America is so fucked in any conflict with China. America couldn't even beat Illiterate Afghani with busted-up AK-47s who never even heard of 9-11.
The reality of a modern major war with China, an ocean away, with no logistical supply chain, is that it will be fought and over within weeks, culminating with the launch of nuclear weapons.
I don't think there is anything wrong with it. You are looking at hunting as a sport. I am looking at hunting as a means of obtaining food. I used to go hunting for rabbit and pheasant mostly, for food. It's way more humane than modern livestock for chicken, pork, cows, etc, and for deer, it keeps the population to a manageable level since most of the natural predators were unfortunately wiped out.
It's real. It's how dehumidifiers work. It's not energy efficient, and more suitable for short term emergencies where you can't set-up an RO to pull water from a local lake.
It could definitely happen. Civilization will first collapse, maybe some humanity might hold on. We'll see 500 PPM CO2 by 2040. It's right around the corner. Mass starvation and die offs of billions, may lead to resource wars, and then all bets are off.
Call me a doomer, but I don't think humans have even 1,000 years left without major sociological revolution that focuses on the welfare of humanity and the planet.
The whole concept of crewed space travel using rockets of any type (including shuttle) is flawed and will never work, it's too expensive, not good for the environment, and not scaleable. Humans have no business going to space, it's just a flag waving contest. Aerospace engineers have known this is a scam for decades and there's been little/nothing done about it. China might do it someday, we'll see. The only way to get to the next step is to build StarTram, the world's first international space launch port, up the side of the highest equatorial region mountain. If we do that, and reduce the cost per lb by 99%, we can build self-assembling modules in space and then send them out to mine the asteroid belt for rare earth metals, which are incredibly important for the next phase of human civilization. None of this will ever happen, and humans will be extinct before it does. Hell, humans will probably go extinct before even making it to Mars, not that we have any reason what-so-ever to send humans to mars and we shouldn't be holding that up as something to aspire towards.
Yes I agree. Only us true hexbears should be allowed here.
