  1. Planck constant is routinely described as "representing the smallest quantity that exists in reality", or even worse, as "the smallest quantity imaginable". Certainly it is not the smallest "imaginable" quantity. Take Planck length - 1.61622837 × 10^-35 meters. Now imagine a smaller number. There, you did it. But is it fair to think of it as "the smallest quantity that exists in reality". In physics, people often adopt a philosophy where things that cannot be measured also "do not exist". From that perspective they might say that "nothing smaller than Planck length exists" - since it

  2. Yeah, many launches are made like test launches or delivering microsats into orbit by different space agencies. So it would be a great idea to use eco-fuel in the launches I`ve mentioned

  3. Hi Superpolymath, you know you are perma-banned right? I am sure ocean will be around to reban you soon. You know you even had me fooled for awhile i honestly thought you were just some random dude that joined.

  4. "We should try varying the frequency of the DC current." Right there you tell us you do not know what you are talking about! DC current does NOT have a "frequency".

  5. The high risk of Kessler syndrome. Earlier it was a theory, but now more and more experts agree that we gradually move closer to it. The rising number of objects in LEO poses a risk for many of us, and space tug skyrora manufactures is supposed to help us to fix this problem at least a little bit. However, space tug isn't the only spacecraft that can be used for this purpose.

  6. You would need to make a Penning trap(https://en.wikipedia.org/wiki/Penning_trap). The Photoelectric effect looks something like this.

  7. Simon; A small amount of cesium is in a gaseous state, and manipulated with lasers as it falls vertically. A microwave generator flips the spins of the electrons, then a laser energizes the electrons and a detector counts the number that flipped to higher energy states. The feedback from the detector adjusts the microwave frequency to be resonant with the cesium atoms transition state, approx. 9 billion hertz. The waves may be considered a photon. Density does not play a role in atomic clocks.Motion affects clock rates, since motion alters em processes. Thus time dilation is a consequ

  8. What about 3D printed satellites? Had this machine ever produced them or not?

  9. Yeah, I`ve read about this space company. I know another company that manufactures special type of microsatellites that can forecast solar activity. It is crucial to understand what space weather actually is and how it can affect us before recognising the implications of the research to our everyday life and why the prediction of such events is necessary.

  10. You used the important term 'trust'. The 'experts' in their field, trust the educational system that taught them, and believe they are passing on truth, as best they know it, at the present.A patient seeks a diagnosis from a doctor who is more knowledgeable and experienced than the patient. A person takes a flight to a distant place, trusting in the experience of the pilot, traffic controllers, maintenance people, etc. No one can do all things necessary in life, so they must depend on others.Unless a person is deceitful or dishonest, they will provide the best service they can.The one cri

  11. And also, the Dawn Probe. It uses an advanced ion thruster, allowing it to be the first (man-made) spacecraft to orbit multiple non-terrestrial bodies (Vesta and Ceres). This feat would not be possible (practical) using conventional chemical thrusters, which have too low of a specific impulse.

  12. I would like to mention the Parker Solar Probe. Simply for getting closer to the sun than any other spacecraft so far and considering how hard it is to get that close. The space craft which is capable to take samples from the outer corona of the Sun really makes you amazed by it, because of the high temperature it can endure.

  13. Most people who spend time and money in the pursuit of education want to believe they have acquired knowledge that helps them understand the world they inhabit. They trust in the scientific method to find answers to their questions. Their confidence is enough to publish information to others, and the public is expecting 'expert' opinions. Now imagine an aircraft crash scene. Investigators arrive to reconstruct the event.That is similar to the state of human knowledge. The world was already here when humans arrived. They must hypothesize or speculate with whatever evidence they can find as to h

  15. Same answer to your previous questions. 'They' are speculating based on what little knowledge they have. They are making it up as they go, revising their thinking as knowledge increases.

  16. Have you never heard of "conservation of energy"? The heat energy given off when the atoms recombine cannot be more than the energy required to separate them.

  17. Digging through the theoretical physics of his time, Einstein dug up "Lorentz transformations" and built "Special Theory of Relativity" on them. It turned out that this theory "holds the water", so in the rapture of success and based on his "happiest thought in life" that there is no gravity at all, he also launched the "General Theory of Relativity", which was embraced by the "popularizers of science" and who from theory made their "business". And as is usually the case, the inventor was often unaware of what he had actually found. In 1927, the famous physicist and philosopher Heisenberg

  18. In India, yoga has been there for centuries before science or modern medicine came in to the scene. Pranayam (special breathing exercises) is a part of yoga.

  19. Since science is not constant for all time, there is no value in the judgement that something has science in it or not.:confused: Take for example, the medicications prescribed in Ayurveda, the medical world is slowly awakening to the fact that they often work, and are invariably less harmful then many allopathic drugs. How did Ayurveda develop? Not by controlled experiments modern pharmacs swear by, but by long painstaking experience of some wise sages. So, the methods employed by the modern pharmacs are in no way the ultimate methods to discover substances in nature that are useful fo

  20. That's what I was saying: religious institution usually amounts to the abuse of something pure. Consider this quote: “Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying, “Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.” He answered and said to them, “Why do you also transgress the commandment of God because of your tradition? For God commanded, saying, ‘Honor your father and your mother ’; [Exodus 20:12; Deuteronomy 5:16] and, ‘He who curses father or mother, let him be put to death.’ [Exodus 21:17]

  21. Possibly most of the star systems will be diluted for a time. Have you actually run a simulation? What will we do if we can't outrace expansion because we don't understand dark energy 😲
