  1. No, the laws of nature imply what we say about nature.
  2. I think Thor did. His weapon is excellent to kill creatures.
  3. No I think the idea of 'god' evolved. People ascribed supernatural stuff to natural phenomena (sun, clouds, water...) this became polytheism (Zeus, Hera, Odin...) and now it's rather monotheism (Jahweh Allah).
  4. Homosexuality imo used to be more discriminated then it is now.
  5. I've read that environmental/cultural factors can have an effect on sexual orientation. But true sexual orientation is due to some regions in the hypothalamus. https://en.wikipedia.org/wiki/INAH_3https://en.wikipedia.org/wiki/Sexually_dimorphic_nucleus It can be. In evolution you can have survival of the fittest gene pool....especially for animals that live in groups. I'm a fan of the gay uncle theory.
  6. Mutations result from errors during DNA replication or other forms of damage to DNA(like radiation exposure)).https://en.wikipedia.org/wiki/Mutation No chance.
  7. How did homosexuality evolve? It's present in other animals as well.https://en.wikipedia.org/wiki/Homosexual_behavior_in_animals
  8. Maybe shipbuilding had a 'big' impact.
  9. The azolla event lasted for nearly 1 million years I think most plants and animals can adapt while the event was going on.
  10. I often don't see and read stuff, but thanks for that comment...my reputation keeps dropping.
  11. Organelles — the cell’s workhorses — mingle far more than scientists ever appreciated. https://www.nature.com/articles/d41586-019-00792-9
  12. When you measure the momentum, for example, you interact with its energy so you change the phenomenon. Yes but you can't know position/momentum without measuring them. Ok but this concerns mathematical logic. Can you measure something without changing it? What does it mean 'additional to HUP'?
  13. Actually there was a measurement. The box can be considered to be a measuring device. By placing a particle in a box you change the uncertainty/probability. The observer effect is the theory that simply observing a situation or phenomenon necessarily changes that phenomenon. This phenomenon can be anything.
  14. In quantum mechanics, the uncertainty principle (also known as Heisenberg's uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, known as complementary variables or canonically conjugate variables such as position x and momentum p, can be known. Because measuring those physical properties change the particle. The uncertainty is a relation of measured properties. How can the observer effect be unrelated?
  15. The environment changes all the time. So what do you mean?
  16. HUP would not exist if there was no observer effect. Without observer effect measuring a particle doesn't alter the particle and you could measure momentum and position repeatedly. Without observer effect you would not destroy a photon by detecting it...the HUP would then not exist. HUP and observer effect are ways we deal with reality. How do you react to my explanation?
  17. Yes but those values only exist when you measure them, you can't invent those values. HUP is only visible when you measure a particle And measurements are subject to the observer effect. The hup is a constraint. If phenomena did not change when measured/observed then there wouldn't be a constraint. When you measure the momentum of a particle then you alter it's energy, you change the phenomenon….But if there was no observer effect then you could measure the momentum without altering its energy and without changing the phenomenon. If there was no measurement/observer effect then particles don't know they are measured and you could measure momentum and position as precise as possible. Without measurement/observer effect, measuring doesn't alter the particle so you can repeat the measurements.
  18. HUP is about the relation between 2 measurements which are subject to the observer effect. Agreed?
  19. The destroying of a particle is also an observer effect...Meh
