The amphibious ships are small and can't carry a lot. The proposed idea made a lot of sense in that it would allow larger ships to be used so less trips and less fuel per ton of aid, but the political will was just never there to keep it running or make sure it was planned thoroughly enough.
Absolutely shameful, but on the plus side military logistics students just got another case study.
Dark matter isn't based on simulations, it's entirely observational.
We observe here that matter generates a gravitational force proportional to the amount of matter present, and we know that to an extreme degree of precision, but when we look at big things like galaxies the force required to shape and move them in the ways we observe would require more matter than we observe within them.
Rocketry companies have always been that way, you're just waking up to it. Capitalistic greed doesn't change my mind that footage of re-entry plasma is the coolest shit I've ever seen
Luckily Canada is getting more and more secular each year, and even people who believe in a higher power are less invested in organized religion. This is a losing strategy for Pierre and the Conservatives, but it probably won't have any meaningful effect until 2029
I'm not saying you don't need the truck (only you know your needs), but I can haul quite a lot with my hatchback + utility trailer. Trucks aren't the only tow-capable vehicle out there these days, modern 4 bangers are quite powerful
There is promising research into mixing hydrogen with existing natural gas pipelines at low concentration (<2%). It doesn't leak any more than gas pipes do already and the low concentration prevents embrittlement. And you don't have to go through the horrendous efficiency of a fuel cell, you just burn it with the gas
Everyone likes to joke about this manhole cover flying around in space, but if you do the math on the aerodynamic heating you get a temperature higher than the boiling point of iron.
