  1. No. Superluminal speeds are inconsistent with causality: there are situations where you can get a response to a signal before you send the signal. Depending on what you mean by parallel dimensions, they are science fiction or an interpretation of QM. Not actually science itself.
  2. Light moves at the same speed as gravity because photons have no mass. Massless things move at c. Massive things move at speeds slower than c.

  4. Different kinds of lead? Which sidesteps the question about cost. None of this addresses my post. What is your point? I don't think that was it. The difference in chemistry was addressed immediately by exchemist. Instead of asking for a followup, the OP doubled down on dubious claims trying to support the notion. I suspect that's the source of any real antagonism. The title was just foreshadowing.
  5. And how does that change the cost of procuring and processing? In a word, no. Whatever you read you interpreted incorrectly. Fragmentation makes for dust which can be inhaled. Alpha decayers are very destructive internally, but not so much as an external dose. More dangerous/more damaging is NOT the same as more radioactive DU is less radioactive than natural uranium of equal mass (U-235 has a shorter half-life)
  6. He fights to overcome a stutter, which isn’t about energy.
  7. Where? No, that means you have fewer atoms for the same mass, which (all else being the same) means fewer chemical reactions
  8. When your prediction fails it’s a clue that your idea is flawed. This is a rather spectacular failure, befitting the flaw
  9. Dividing by zero is undefined, which is what happens when you try and use a crappy definition, which is what W/g is.
  10. No, since mass=gravity/weight is nonsense, as I have explained in another thread. Nothing valid can be derived from it.
  11. First of all, let me say this: post non-mainstream material (i.e. any pet theory) in speculations You need to clarify what you mean by gravity in this equation. Typically we use variables that are precisely defined. I can't really come up with a meaning that's correct. Weight is a force, meaning W = mg, where g is the gravitational acceleration. So m = W/g, but you have weight in the denominator. So you are claiming the gravity is weight * mass, or m^2*g, and I don't know what that means. And since that's nonsense, everything derived from it is nonsense.
  12. I don't know how you would expect me to do that, when I have told you that it's not, and conditions under which it fails to hold.
  13. c is invariant, which means it's the same in all inertial reference frames. If you are at a fixed location in a gravitational field, you are in an accelerated frame, not an inertial one. You will locally measure c to be the same, but that might not be the case if you measure it in reference to some other frame. The difference, though, might be negligible with regard to the precision of a measurement you are making.
  14. Do you have evidence of this for the pipeline? Is that your excuse for not providing support for your claims? Because if you don't provide it, then one can think that your post was just silly spin.
  15. Not being able to get spare parts, and not being able to pay for fuel, is going to put a huge crimp in whatever airline service is still happening. Not having parts to fix military vehicles, beyond what they have on the shelf, is going to further hamper the invasion. I imagine the US and other countries are doing a reassessment of supply-chain issues regarding their own military, and the impact on readiness for sustained deployments.
  16. "No" is correct What you should look at is people whio are developmentally disabled and unable to understand these concepts still grow. Or people who are in a coma.
  17. The Peter Piper Institute being a notable exception. On the internet, nobody knows you're a dog. https://en.wikipedia.org/wiki/On_the_Internet,_nobody_knows_you're_a_dog#/media/File:Internet_dog.jpg
  18. You haven't given enough detail (no mention beyond "test this"), and one instance is anecdotal.
  19. Even unprocessed uranium is much more expensive than lead ($30-40 per lb for uranium oxide vs $1 per lb for lead). Depleted uranium would cost even more.
  20. I'd like to know how a US president vetoes projects occurring outside of its borders. Biden dropped support for the Israel pipeline, as there were concerns about environmental impact and economic feasibility, but that doesn't stop it from happening. The only Canadian pipeline that pops up in a search is Keystone, which was for tar sands oil, and it went south, not east. So it was in the US, which is why it was under US jurisdiction.
  21. It’s not, but Pauli prevents particles from being in the same state. Neutrons and protons obey it. What? It’s definitely present in atoms, which is kinda what defines the atomic length scale

  24. strontium has been banned as a sockpuppet of Ragingmoron. This was not in evasion of a ban.
