By showing us how small in space mass can be, black holes continuously generate space.

Disclaimer: The hyperloop is an absolutely shit idea right now. I do not support building in any form right now.

Now to the shower thought: Theoretically, a hyperloop can get you from place A to place B on the planet in less than 40 min (back of the napkin calculations assuming constant acceleration and deceleration of around 1G). Being completely underground (more on that below), it would also be a really good piece of infrastructure safe from arial/orbital bombardment.

Now to the obvious problems: We need the tube to be very very straight to achieve high speeds without killing our passengers. We would want the hyperloop to enter city centers. Building such a straight thing in city centers would require a lot of demolition. Therefore, we would have to get it underground. Bringing it on the ground again outside cities doesn't make sense because we would be introducing steep upward curves, thus reducing its maximum speed. Therefore, it makes sense to build this thing completely underground. Building underground also gives us many more benefits like not having to do much land acquisition, safety from violent attacks and so on.

Our tube would have to be incredibly airtight. It absolutely cannot have any leaks anywhere. Also, we need to be able to achieve incredibly low chamber pressures and maintain them.

If we are building this underground, we would need a shit load of energy to dig and transport the material outside the tunnel. We would also need a shit load of steel and other resources for these incredibly long tunnels.

Where do we get this energy? Where do we mine these resources without destroying the planet? Now this is where the "future" part comes in. We would need energy to be incredibly cheap. The only viable long term method (by "long term", I mean it from the civilization time scale) would be via nuclear fusion. When is nuclear fusion happening? Well, it's only 30 years away! /s Jokes aside, the energy source might be when nuclear fusion not only becomes possible, but also incredibly cheap (the nuclear reactor shouldn't cost billions lol).

About the resources? Well, we probably need to mine them on the moon, no? The moon has A LOT of them right on the surface. If we can mine them and send them back home, we solve our resources problem!

Well, you might ask- doesn't it make more sense to just have spaceships with engines propelled by nuclear fusion that exit the atmosphere, go at hypersonic speeds and then drop in? Why build expensive underground continent spanning tunnels? Well, what if we are attacked by aliens? They could easily blockade our airspace. Hell, just dropping a few million stealthy pebbles in our lower orbits would be enough to stop all hypersonic travel (the risk of ships exploding on contact with these pebbles would be too high for air travel to continue). Hypersonic spaceships would also face the problem of traditional aircrafts- you would need to build spaceports far from city centers. These spaceports would require a lot of space and cause a tremendous amount of noise pollution (constant sonic booms for every launch and landing).

Therefore, I think I have made my mind. I think I would be voting for a hyperloop proposal that possibly would be tabled in our direct democratic government a 100-150 years from now!




Some of the posts in this community are just crazy out of whack.


So I thought about this in the shower amd it makes sense to me, like praying and stuff never worked for most people I know, so a direkt link to god gotta be unlikely. That made me conclude that religion is probably fake, no matter if there's a god or not. Also people speaking to the same god being given a different set of rules sounds stupid, so at least most religions must be fake.


I think capitalism can be understood as a living entity, a being composed of billions of smaller beings (people), essentially cells. It evolves (legally and through market innovations), has an immune response (police), and grows and reproduces itself (imperialism). The cells are independent life in their own right, but they exist almost wholely within the body of capitalism and the structure of their existence reinforces their participation in the greater whole of capitalism. All complex organisms are composites of smaller organisms and I think it makes sense to reason about capitalism and how to go about changing it or destroying it from this lens.

Sometime, probably close to 20 years ago, but perhaps more recently, you heard a dial tone for the last time and you didn’t even realize it would be.

Edit: if this shower thought is too confusing to be useful to you, then here is a quote that gives some of the same guidance, is simpler, less philosophical, but less broad: “Don’t waste your time chasing butterflies. Mend your garden, and the butterflies will come” - Mario Quintana


Until you eat your vegetables, they are just hopeful intentions


It's basically the same thing, but out of the other end of the GI tract 👌💦💩


Every week or every month each level of government throws a party funded with taxpayer dollars, and attendees are selected at random from the residents and given advance notice of the party schedule.


Given how many people treat speed limits as suggestions, at best, having your vehicle obey the limit would turn some people off of them.


Content never really dies, it's just recycled to lower and lower tiers.


I think this is the biggest problem I see in people trying to understand deeper fields of study, a concept is just too large or out of our perceived reality to even make sense without years of knowledge. I think people fall into the "woo woo" just because it's easier to not really know versus becoming a doctorate in a field of study who has slowly built that knowledge on the fundamental principles needed.

But either way, when you start, you just have to accept that something has a cause and effect. We can't see most fields, just have to accept they are there and interacting the proposed ways because of our tiny little sensors. Sometimes, we just have to say "ok" even if it boggles the mind.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
