  1. How do I tell if something is made of normal matter or has exotic matter in it?
  2. ! Moderator Note And we went through this before. It ended up with the thread being closed, and you were told not to open up a new thread on it. Doing an end-run by bringing it up in a thread on another topic isn’t allowed.
  3. Exactly what the article points out. There was funding to investigate the virus, but that’s not the same as researching “gain of function”
  4. What would be the demarcation between these two types of masses? Are asteroids small or exotic? Moons? Comets? Gravitational interactions have been observed on fairly small masses. Are ~1kg lead spheres normal matter?
  5. You’re asking him to show he’s not lying about something he says doesn’t exist - the financial support. How do you show that it doesn’t exist? What’s to explain? Fauci already made his statement. He shouldn’t have to address baseless accusations, and the link provided by exchemist indicates that this is baseless.
  6. Tom Booth suspended for repeatedly bringing up a discussion that was locked, despite multiple warnings.
  7. ! Moderator Note Please provide evidence that this premise is true
  8. How would Fauci prove a negative? Why doesn’t Rand Paul have to present actual evidence? What is the paper he alludes to? How do we know his allegations are accurate/true?
  9. How can a cylindrical or spherical coordinate system have a curve?
  10. Because, as I said, time isn't an object or substance, or anything that has momentum or energy. It doesn't travel a physical path. A model with time as a substance would very likely fail, unless you also changed the rest of physics. You need a new model (and name) for what we call gravity, for instance. But I don’t think anyone can falsify a model that doesn’t exist.
  11. Skydiving works here, too. ”I never knew dogs could scream!”
  12. I don’t recall these being described in the OP. You had a tube and a turbine. I think my disbelief was well-founded, based on the available information.
  13. That wasn’t one, so...
  14. You made an assertion without backing it up, so thou doth protest too much, methinks.
  15. No, we know Coulomb’s law works. If you contradict known, confirmed physics (and you have), you’re finished.
  16. What about a proton and a positron? Same mass relationship, but a repulsive force. But electrons do more than "not get close to each other" - they actively repel, with the same force as exists between two protons. The electrons are pulled with the electrostatic force. Deuterium doesn't have twice the attractive force on an electron owing to the extra neutron. The effect is small, owing the different reduced mass of the system, which shifts the energies a small fraction of a percent - not anywhere close to a factor of 2.
  17. There's no need. The Egyptians didn't make it in a lab. You can find slate in lots of places.
  18. No, they are not. Different department in universities; often called out as distinct from science in their organization. (look at how many have "college of science and engineering" or separate colleges altogether) Different approach to solving problems.
  19. I provided the calculations. Even if you tapped in to the whole decay chain there is a tiny amount of power. If it's just radon, it's far, far less. (Plus that much radon would likely kill everyone.) I seriously doubt that.
  20. No, they're different by a factor of about 3 An interesting question might be whether they had similar values at some time in the past. With less expansion I would expect the difference between (age)*(speed of light) and Rs is smaller.
  21. ! Moderator Note https://www.scienceforums.net/guidelines/ From 2.7 Links, pictures and videos in posts should be relevant to the discussion, and members should be able to participate in the discussion without clicking any links or watching any videos. Videos and pictures should be accompanied by enough text to set the tone for the discussion, and should not be posted alone. We've had that in place for years. ! Moderator Note This is moot. You haven't supplied a link to an article. ! Moderator Note The brain controlling the heartbeat is a far cry from two brains interacting with each other Don't bring this up again.
  22. The calculation looks fine. It's the radius of the observable universe that's wrong.
  23. ! Moderator Note You have been here long enough to know that "go watch this video" is not in keeping with the rules, and that simply restating your claim is not going to fly. Last chance: provide actual scientific evidence that this claim is true.
  24. The part where it's powered by radioactive decay has already been dismantled.
