Wait, dumb question. In a vacuum can I go as fast as I want. Like as long as acceleration is cool. Is there technically no downside to increasing speed. Just like we’re technically on a planet spinning fast. If I was in a ship in a total vaccumu and it accelerated at a pace that I could handle, could that ship go faster and faster like a bajillion km a sec and I would just be like sitting there enjoying the ride.
From your perspective, eventually things don’t move faster by a noticeable amount, but the length of objects starts to shorten, so you can pass much more stuff at a slightly faster speed. You will never see anything move faster than light, it just shortens itself into a 2d object with 0 depth as it approaches the speed of light.
But then there is no limit to how fast we could move? Like there is no speed our heads would explode. There’s no side effect of speed I guess is what I’m asking. Like 2x speed of light would be no different to us then 5km/hr. Sounds like the only thing would be stuff external to us like the length getting shorter. I get in atmosphere we’d be shredded. But technically we can just go.
Yes, movement is undetectable unless you have something to track your movement against. In fact, there’s no way to define “staying still” that’s true for everyone in the universe.
You can only feel acceleration, not constant speed movement.
2x the speed of light is impossible. As things move faster, time slows down so they can’t make as big of a change to their movement speed using the same amount of energy. Instead, lengths contract so your destination doesn’t appear to be as far as it would have been at the start of your journey.
Here is my take away, speed is not real. Its a concept created by Big Relativity.
Just mindblowing to me that speed does have no effect on us under certain conditions. Like learning that pregnancy can work in zero G. As if we are star people not just Merpeople from the ocean.
From John Bazell “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.”
Another government pushed garbage meme misrepresenting contents of “plant based alternative” promoting replacing normal meat eating, with CANCER CELL “meat” guess what those who will bit this bullet gonna end up with? xD…
Not saying that the person in the post is correct in conflating those words, I don’t think that’s accurate at all.
However, it is disheartening to see so many ill-informed comments about fatness here… It’s way, way more complicated than just “calories in/calories out”. Even the extent to which it’s unhealthy is more complicated; obesity is linked to higher risk of heart disease, but also linked to higher probability of surviving strokes/etc. A lot of the problem stems from the fact that BMI is a nearly useless metric.
Human beings are subject to the laws of physics. If you eat more calories than you consume and do not otherwise eliminate from the body, they will still be in the body. The body stores them as fat. This is simply the mechanics of biology. If it weren’t, things like Ozempic would not spur massive weight loss.
We have more obese people now than have ever existed. Countries that do not have US/Mexico levels of easy access to heavily processed, calorie-dense foods do not have obesity problems like we have. Clearly, calling people names and making them feel bad is not a good way to get them to adopt healthier habits. However, there are plain, uncomplicated things that people can do to lose weight that will work, but they will ONLY work if the people want to change, are honest with themselves and truly stick to the changes they need to make.
Losing weight is absolutely within reach of 99% of obese people, but comments like this reinforce the absolutely incorrect notion that getting healthy is some big mystery that’s for a different class of people to solve. It’s defeatist and makes it seem like a problem that a person can’t solve on their own, which is straight up wrong.
The plain, uncomplicated things you can do? Find out how many calories a body of the weight you want to weigh uses in a day. Limit yourself to those calories. Given time, you will be that weight if and only if you stick to the plan. It may shock some people how many calories they actually consume in a day, especially if they drink soda or juice with any regularity.
The difference in usage that badboy would get during a football game versus a gig at the same stadium would be enormous. Things like flush cycle frequency and when to turn the system on/off to conserve water. Nothing massively sinister - boring facility management stuff mostly.
