  1. You need a fairly deep understanding of the nuts and bolts of a field to start productively philosophising.
  2. Cool. Is it emitted from merging black holes in a polar, conical fashion, like a GRB, or concentrically through 360o in all planes, or just in one plane? Popsci animations seem to show it radiating all around in one plane.
  3. But it can be viewed sinusoidally, just using two points, can't it?
  4. The BBC infographic I saw suggested there was a 5000ft depth at its last known location, which is beyond the tolerance of a sub hull if it lost bouyancy, I think.
  5. Yes, my response to music is quite deep and I often play music in my head but only after hearing a piece many times unless the lead melody is simple. I know I don't hear it all but, I think, what you don't know, you don't miss, as long as it's a meaningful experience. I don't think normal-hearing people hear and process the same way anyway. We all hear what we want to hear and discard the rest. Can you hear the notes on the piano and can you hear the difference in pitch as you run across the keys? Concerning your original question about research into it, it seems to be rather scarce and not of high quality according to this following metastudy paper on the causes, so I imagine research on your specific question will be very hard to find. If you want to read the full paper click the link at the end of my quote. This is a 2013 paper, so it''s quite recent.
  6. When you note the time on your mobile phone and put it in your pocket, does it carry on from where it was when you last looked at it?
  7. You and I live in a secular society, so we can't appreciate what Moon''s moaning about.
  8. You can measure universal expansion from the redshift of an astronomical body, which is a single parameter i.e. a single frame, whereas you need two frames, represented in the two arms, to measure GW's. When a GW passes through the arms, the relative time between the arms is not in sync because spacetime is being perturbed differently in the locality of each arm by the GW and this difference creates a sinusoidal wave when the measurements are combined as they happen.. Edited to add.
  9. i wonder what the numbers are for men being harassed in their lifetime. From personal experience, women can be just as base and sexually aggressive as men. Maybe not as often but it's not insignificant.
  10. In what way do you think you are amusic? I'm severely deaf myself to the extent that I have to supplement my aided hearing with lip-reading except in perfectly quiet environments. I'm about 70dB for speech.
  11. Spacetime, which changes in the LIGO experiment, and space, which expands in the universal expansion are two different phenomena.
  12. Yes. The LIGO experiment relies on the invariance of the speed of light, which stays the same regardless of which arm (frame of reference) is moving : the time component has to change which is what is measured in the LIGO experiment.
  13. A ruler will not expand from universal expansion but will shrink/expand in a gravitational wave.
  14. They should be each treated with the same objectivity and dispassion until the evidence is concluded and guilt established, or not.
  15. Think of the two arms of LIGO as two different frames. Each time one arm is affected by one part of a gravitational wave, the arm of the other is affected by a different part of the gravitational wave, so, one is shrinking and the other is expanding but only from the perspective of the other arm i.e. from a different frame of reference. The universal expansion is entirely different and is resisted by sufficient gravity and intramolecular forces. If there is a distance of about 200 mlyrs between galaxies they will separate with the expansion.
  16. Is there any possiblity of the embedded particles of lead actually leaching out of the glass, if it''s not further fragmented? Once the exposed surfaces of the screen pieces have oxidised that'''s it, isn't it? You can treat it like pieces of lead metal that will quite quickly become inert.
  17. Doesn't lead oxidise only the surface then it stops and is pretty waterproof to the remaining metal underneath? It wouldn't have been used in plumbing otherwise. Plumbum is the latin name for lead and a person who worked with it was a plumber! I think once the exposed surfaces have oxidised, the actual volume/mass of free lead in an object is irrelevant because it is effectively inert.
  18. Cool stuff. The line between bacteria and human is extremely blurry when you think how important mitochondria are to our existence, originally being autonomous organisms themselves; the same with chloroplasts in plants.
  19. Parasites have no benefit to the host. Symbiotic relationships are mutually beneficial, generally. Gut bacteria can have a significant effect on behaviour by interacting with the host to produce the neurotransmitter.serotonin. Both the host and commensal bacteria regulate each others activities. They are part of the hosts critical makeup.
  20. The great majority otherwise you would be ill. For example, when you get diarrhoea, pathogens have got the upperhand, in population terms.
  21. Drink decaffeinated coffee and be prepared for some headaches after about two weeks for a few days.
  22. Good medical ethics has no frontiers. Besides, cancer can be caused by ones actions/inaction/excess. Is the smoker, cirrhotic alcoholic or obese person totally blameless if they get cancer? Having a sex life can get you papilloma virus and cause cancer...are you to blame? it is not productive to have a judgemental agenda like yours.
