  1. On the contrary, we know exactly what it should look like. Spin 2, chargeless, massless and therefore, of energy related to their frequency. Unfortunately, you don't type in 'graviton' into a search engine at the LHC, and its track magically appears. If they exists, their interaction with massive matter has an extremely low cross section, making their detection almost impossible.
  2. Sorry CharonY. The only one I'm familiar with is the University at Buffalo, and that seems substantially more expensive than my local universities like Brock or McMaster.
  3. That seems like a lot of work ( and possibly dangerous ) when you could do the same with a GPS/computer controlled, engine speed governor. GPS tells computer what the speed limit is in that particular area; computer cuts back ignition when that speed is reached. Don't think many people would like it.
  4. QM, as a theory, is self consistent, and is not counterintuitive at all; it is a differing paradigm ( or basis of thinking ). The 'interpretations', which try to describe QM, and relate it to common everyday occurrences, struggle to be sensical. ( my cats really hate the Copenhagen interpretation, and get upset when I try putting them in a box with cyanide ) Don't take the multiple interpretations too literally.
  5. That comes across as a strong dislike of the already benefitted few. Let's face it, any system for equalizing opportunity is implemented as a redistribution from those who have, to those who don't, with the Government as the middle man. There is an increasing rate of taxation to go with rising income. The intent should be that this helps pay for education for underprivileged students. Yet it 'disappears' into defense spending ( the US has the biggest, and best equipped, military in the world, yet that is no deterrent as it is always getting into wars ), or it 'disappears' into projects in congressional districts ( because politicians have to be bought for their support ), or it 'disappears' to build walls ( thanks D Trump ), or to bail out big Banks who are too big to fail ( even though they caused the problem in the first place ), etc. In Canada we have subsidised education, where you do have some costs, but the Government subsidizes the larger portion. It works very well ( even though the government subsidies are different in different Provinces ) as it ensures the student puts some effort into it, as it does cost him/her some money. If I had a child, and he/she lived at home, they could attend the local University ( Brock ) for about 8000 can$ per year ( about 6000 us$ ). They could earn that in the summer or from a part-time job, without incurring a four year 160 000 $ debt at a( cheap ) American university. Then again, is seems like subsidised education is anathema to Americans as subsidised Health Care is. I don't know whether to say 'pity' or 'shame'. As for Affirmative Action... In a perfect world we would not even notice 'features' of different groups that apply for admission. And I think we can all agree on that. In what world, then, does it make sense, that in the case of two equally qualified individuals the tie-breaker is determined by 'features' of whatever group is needed to fill a quota ? Is that not racism to combat racism ? You can pave that road with all the good intentions you want; it still leads to the same place.
  6. I am a Trekky, so I will not put down Star Trek: TNG. ( Heisenberg compensators in the transporter … nice ) However … Entanglement is similar, but not quite the same as a 6sided die, a coin, or a pair of shoes. The difference is that once you see a 1 on the side of the die, the other side was always a 6, once you see heads, or a left shoe, the other side was tails, or a right shoe, even before you saw heads , or the left shoe. Entanglement is not like that, spin up, or down, is undefined in the observed particle, or its sister entangled particle, until the common wave function is collapsed by the observation on one particle. So, although similarly a type of correlation, in practice it is very different. Your OP postulates the 'graviton' being responsible for space-time. I'm not sure you are using the accepted science definition of 'graviton', or your own made-up definition. ( you should clarify, we only use accepted definitions; makes it easy to understand each other ) Space-time is the geometric field of gravity, and excitations of the field give rise to virtual or real particles ( depending on a threshold of action ) in any quantum field theory. In accepted Physics, the quantum particle generated by excitations of a quantized space-time field is given the name 'graviton'; with very specific properties.
  7. I think that's mostly a problem with the 'American' way of life ( although it is quite common in most western societies ). We equate money with power. The idea that you can buy anything, from school admission to politicians, or even the Presidency, is exemplified by your current President. I am suggesting that equal opportunity should be achieved by bringing everyone up to the same level, not bringing the 'have' to the low level of the 'have nots'. And suggesting reverse discrimination to fix the problem of lack of equal opportunity is akin to suggesting the solution to gun violence/ mass shootings in schools, is to put more guns in schools with armed teachers.
  8. No distinction ? Consider wealth. Is the problem with wealth inequality that some have too much ? Or is the bigger problem that some don't have enough ? What some might consider having 'privilege', some others might think everyone should have.
  9. There are many crimes which are impeachable … if you are a sitting President. Many people, who are not President, have received Presidential pardons for the same crimes. The way I read it, if impeached for a crime, you cannot be pardoned for that crime. R Nixon resigned before he could be impeached of his crimes, so they were eligible for a pardon. I would think D Trump cannot be pardoned in any way for the charges brought against him in the articles of impeachment. ( then again, no one ever asks for my opinion in legal matters )
  10. I don't understand ... Is privilege the problem ? Or, is it actually, lack of privilege for some.
  11. I've been to a few 'wild game' dinners. Not really my 'cup of tea', as I prefer what I'm accustomed to eating. But some definitely like 'strange' foods.
  12. Vulcanic soils are especially good for viniferous grape growing, and excellent wines. The area around Mt. Vesuvius, near Pompeii in southern Italy, is very fertile. So, about 19-20 centuries ( since the 79 AD eruption ) should do it.
  13. While a large local mass-energy density will result in a Black Hole of any size, this will only result in locally large space-time curvature. A collapse of the whole universe requires a global curvature. If the mass-energy density of the whole universe ( not just observable ) exceeds a certain amount, then the global curvature will be positive, and the universe will close in on itself and be unbounded but finite ( 3D analogy would be a sphere ), even as it continues its expansion. If the mass-energy density is equal or less than the critical amount, it will either be unbounded flat, or unbounded hyperbolic ( negative curvature, saddle shape ), and both are destined to expand forever. The only possibility which supports a re-collapse would be the positive curvature, hypersphere topology universe, but our current observations seem to suggest a global curvature that is very nearly flat, and accelerating expansion.
  14. Apparently they also combined the results of two separate trials ( the other is in Brazil ? ), which isn't really accepted procedure. I got the impression that the half-dosing, which resulted in better outcomes, was not intentional, but an 'error' on the part of a 'contractor', Srtingy. They still have some serious work to do, before they can make any more claims.
  15. AstraZeneca is reporting some dosing irregularities which have eroded confidence in the results reported last week. This may affect their application to have their vaccine authorized for emergency use by regulators, in time for early 2021 roll out.
  16. I, myself, have won the lottery several times, in 'other' universes.
  17. Language, guys. Young kids read this forum. Don't contribute to the downfall of young people's morals . From Stringy's link/quote "Our case STRONGLY continues, we will keep up the good... fight" Yeah, just like OJ was looking for his wife's killer … on the golf course . ( what can I say, I'm in a good mood; the Trump era is finally drawing to a close ) "
  18. The only 'science' that adage is remotely true for, is Holistic, or integrated, Medicine. These alternative medicines ( or quackery ) is any practice that aims to achieve the healing effects of medicine, but which lacks biological plausibility and is untested, untestable, or proven ineffective.
  19. I read that too, and was puzzled by it. Can you shed any light on why a half dose followed by a full dose would be more effective than a full dose followed by another full dose ? And not just by a bit, but 50% more effective ?
  20. Your posts give me headaches, Capiert. And its not just the formatting ...
  21. Great idea. Since climate change is such an existential threat, what would be a better weapon than militarizing the weather/climate ? If you could destroy their harvest and starve another nation, tear apart its infrastructure with hurricanes, or drown it under massive rains/swollen seas, there would be no need for planes, ships, tanks and atomic bombs. I'm joking. ( before everyone jumps on me and gives me a beating )
  22. Further to Swansont's comment about linking such postings, it is also customary to quote the error of the measurements. If both measurements are +/- 5 km/sec , very likely when dealing with astronomical distances ( and possibly not quite standard candles ), then they are equivalent in the range of 68.5-72 km/sec. They might not be different measurements after all.
  23. Believe it or not, the Russian military is alleged to have carried out tests of pilots jumping, without parachutes, into snow. "In the early 20th century, parachute silk was rare in the Soviet Union, so the military conducted experiments with air-dropping soldiers into deep snow without parachutes." From https://en.wikipedia.org/wiki/Winged_tank
  24. The equations that 'allow' time travel are self-consistent. But the fact that the equations 'allow' it, doesn't mean that time travel is possible. And certainly NOT that time travel can be self-consistent. Besides, where would you get the 1.21 GigaWatts ...
  25. These 'oversight mechanisms' are common in many Governments ( even Canada ), but they don't usually have any power over the Government. They are there primarily to 'shame' the Government for having breached certain standards of behaviour, in the eyes of the voters. I don't know about the situation with B Johnson in the UK, Stringy, but I'm sure you realize the Trump Administration has no shame.
