  1. The “killing the operator” was a hypothetical scenario that came up in discussion.

    They didn’t change the value when they redefined it. It’s just now defined in terms of physical constants. It would only matter if you were trying to experimentally realize the value, since the method would differ.

    Time is relative to the frame of reference of the observer, being affected by speed and position in a gravitational field. Aging is a more nebulous concept. As Phi notes, it’s probably a biology issue, so you should specify which concept you wish to discuss. Aging does not affect time. Time affects aging.
  4. It’s calculus. https://en.m.wikipedia.org/wiki/Calculus
  5. f(x) represents a function of x dx is a differential; it’s found in an integral (you could integrate f(x)dx) or as a derivative, as in dy/dx
  6. You need better - i.e. technical - resources. You cited and encyclopedia earlier. This topic is more advanced than a high-school report. Perhaps you’d be better served by asking questions than making a proposal that’s not really based on solid science.
  7. Another way of saying that is that you are violating known conservation laws. How do you artificially produce gravity?
  8. “This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L)” This is true statement the does not imply that the two numbers would be equal. You would have to convert between them. It’s like saying that an amount of money given in US dollars could be expressed as Japanese yen.
  9. A liter is 1000 cm^3. 1 m^3 is 10^6 cm^3 So right off the bat you’re off by three orders of magnitude no Source? Your maths are atrocious
  10. Let’s see the maths
  11. Solar system exploration isn’t the same thing, though. You can investigate new things without much overlap. But if one probe is sent to a distant world to see if there is life there, what benefit is there sending a second one, years later, but before any data is collected?
  12. They will not accept that which they’ve been paid to reject. Shocking.
  13. Heating the cold regions doesn’t help solve the global warming problem, it makes it worse. More stuff in orbit, especially highly reflective stuff, will not be popular with astronomers. It always sounds simple when you don’t consider any details whatsoever. As evidenced by all the times it has been done?
  14. It seems likely that deep space probes would be a collaborative effort, like the ISS, in order to defray costs. They would not be Bracewell probes; the OP went out of their way to specify one particular type of probe. These would have to be some other sort of probe.
  15. Not huge, though. Total solar power incident on the earth is in excess of 10^17 watts. A 1 Megaton bomb is about 4 x 10^15 joules, which is the solar energy we get in a few tens of milliseconds.
  16. Musk doesn’t appear to be all that bright. He’s an example of the myth that getting rich is a result of being smart, which ignores other factors (like being lucky, being given large advantages, and being sociopathic) Except it wouldn’t disassemble CO2 Now you need to explain what “kinetically charged” means.
  17. No, intelligence. If intelligence is innate, then you shouldn’t be able to improve it with test-taking practice or strategies. If you are measuring intelligence and not knowledge, then your score shouldn’t depend on whether you know what particular words mean, but it does. There shouldn’t be cultural biases, but there are. All of these are flaws with IQ tests. So why was Feynman’s IQ 125? He obviously had a high capacity to acquire, understand and use knowledge.
  18. How would this not violate conservation of momentum?
  19. Elon has only a bachelor’s in physics and is not an engineer. Take their claims with a large grain of salt. Killing humans would be problematic “Carbon dioxide” and “beta decay” are not single words But, as has been pointed out, no, this would not happen, and even if it did, how would this cool the earth? neutrons are not charged.
  20. He’s being investigated, so it hasn’t been determined that he broke the law. But he had two earlier shows in Germany, so I wonder why this wasn’t an issue after the first show, or if he was warned and went ahead anyway.
  21. Any particle-antiparticle pair can annihilate.
  22. The article cites data from the US. Inflation data from any other country would be irrelevant. Looks like that’s for Puerto Rico. And since it’s a future increase, there’s no data to look at. The article specifically excluded employees who get tips

    They are posting from Pakistan, so…
  24. But it’s just going to be a re-hash of what already exists. And right now, from examples I’ve seen, not very good. Hollywood does the re-hash already, but I think people will get sick of it.
  25. What specific jobs are in danger from a language algorithm? So-called AI interpolates from what it’s trained on. It does not innovate. How is this different from the “automation will take all our jobs” cry that we’ve heard for decades now, and has fallen well short of the forecasted doom?
