  1. Youtube is also full of dishonest and crackpot videos. There is no way of telling these apart other than looking at the credibility of the source. The way to judge the credibility of the source is to find the published papers by these "renowned scientists". At which point you might as well post a link to the science, rather than some popularised and simplified account. I assume you are not just believing everything you see on yootoob - although the quality of your arguments does leave me wondering (say "prove" one more time and it will confirm you are a crank). I would certainly be suspicious of anything published via such a route. On the other hand, if has been published in a peer reviewed journal, then it has greater credibility than either of those.
  2. If there is some interaction, I suspect it will be smaller than the errors in my estimates - some of which are within an order of magnitude at best. I probably should have rounded more to do a proper Fermi estimate: http://what-if.xkcd.com/84/
  3. A bit like your posts and your blog then. I thought you would appreciate it. Just trying to make you feel at home by posting random nonsense (and demonstrating no intelligence).
  4. Please show how you calculated this. I would assume the probability of reality is 1. But what do I know.
  5. Thanks. Some of those links are very interesting. Please remember to provide supporting references in future. However, some of your claims are not supported by any of them (e.g. melanin being a superconductor). And some of your sources are extremely poor quality. I would recommend you stick to peer-reviewed science in future. (For example, I would assume that any story on pesn.com is a lie or a scam, without some good evidence otherwise.) And try to avoid yootoob videos. They are, in general, worthless as a source of reliable information. Similarly, the fact that surrogacy services exist in India is hardly surprising. I imagine poverty in the country is a bigger factor than melanin. You haven't shown any such causal relationship. Neither have you shown that India is a larger source of surrogate mothers than America or Europe.
  6. Citation needed. Citation needed.
  7. Citation needed. Citation needed. Citation needed. Citation needed.
  8. I pay $60 a year for a cloud backup service. I think it is worth it...
  9. So, from here we have the mass of hydrogen in the galaxy as about 10% of the mass of the stars, or about 5x10^9 solar masses: https://en.wikipedia.org/wiki/Milky_Way#Size_and_mass And here, we have the specific heat of hydrogen as 14300 J/(kg K) http://www.periodictable.com/Elements/001/data.html (This is not very accurate as that is for H2, and most of the hydrogen in the galaxy is monatomic. And the specific heat varies with temperature, and possibly pressure. But it will have to do.) So putting all of that into Wolfram alpha: 5x10^36W / (10^40 kg * 14300 J/(kg K)) http://www.wolframalpha.com/input/?i=5x10^36W+%2F+%2810^40+kg+*+14300+J%2F%28kg+K%29%29 We get 3.5x10-8 K/s (kelvins increase per second) Which means that it would take a billion years for the temperature to rise by 10 degrees. I suppose that is quite interesting.
  10. Indo-European is a linguistic term. It describes languages, not peoples.
  11. Here is one key bit of information you need: 5 × 1036 W – astro: approximate luminosity of the Milky Way galaxy.https://en.wikipedia.org/wiki/Orders_of_magnitude_%28power%29#Greater_than_one_thousand_yottawatts Then you need to look up the specific heat of the gas in the galaxy. You can ignore the dark matter, for obvious reasons. And I suppose you need to decide if your "furnace" has a constant volume or a constant pressure.
  12. Energy in the form of mass, yes. But not thermal energy. No, there are only 400 billion, as you have read That depends on the time. The temperature will rise as the stars radiate energy and there is nowhere for it to go.
  13. From what I have read, they can usually be trusted in this way (after all, if they got a reputation for not providing a decryption key, then people would stop paying). There are, as with any business, a few rogue traders. I would invest in a proper backup solution to make sure it can't happen again.
  14. No, that isn't what it says. Read it again and try again. Is the problem that English is not your native language? But if it did say that there were the same number of stars in the halo (it doesn't) then that would be 2 x 400 billion, or a total of 800 billion.
  15. It wasn't a question. (Demonstrating your impressive comprehension skills again.) Are you assuming an unlimited source of energy? Or that all the hydrogen will be converted by fusion in a few billion years? If the former, then the temperature will rise to infinity. (BTW, this would be a variant of Olber's paradox, which is yet more evidence that the steady state model doesn't work.) If the latter, then you just need to work out what the total mass of the stars is and, as an approximation, assume all the hydrogen is fused to helium. That will give you the total energy. And from that, you can work out the final temperature. For someone of your outstanding intellectual skills, that shouldn't take more than about 10 minutes. Let me know what you get.
  16. You seem to have survived pretty well for the millennia before those things were invented.
  17. It depends how long you leave it there. The longer you leave a source of heat in an insulated environment, the hotter it will get. Do these questions have any point? How long do we have until you start making stuff up and saying "do you agree"?
  18. If it is the original Cruyptolocker then you can get a free recovery key: https://en.wikipedia.org/wiki/CryptoLocker#Takedown_and_recovery_of_files If it is another variety, you may be out of luck (a few others have been cracked). Otherwise, if you don't have backups and don't want to pay, then you have lost the data. You will also have to make sure the malware is removed (Malwarebytes is usually good at this.)
  19. Is the furnace gas-fired or electric? (Or, to put it another way, what the heck are you blathering about now?) In the unlikely event you are interested in the science, you could take a look at this: http://www.nasa.gov/mission_pages/chandra/multimedia/hot_gas_halo.html
  20. And there certainly isn't any evidence to support it.
  21. If you read the full paper, you will see that they do a lot of detailed analysis of what the effects of this type of dark matter would be, what the observational constraints are and so on. In other words, they have a model. On the other hand, you have some colourful pictures.
  22. That article is so vague as to be useless. http://arxiv.org/abs/1303.1521 Nothing to do with supersymmetry though. This would appear to require a completely new, unknown types of particles.
  23. For some reason I misread you as saying 117 elements. Sorry about that. Although some supersymmetry particles are candidates for dark matter, they are not constituents of atoms. Atoms, of any atomic weight, cannot be dark matter. Not even if they are atoms made of supersymmetry sparticles.
  24. Oh dear: "All elements from atomic numbers 1 (hydrogen) to 118 (ununoctium) have been discovered or synthesized" https://en.wikipedia.org/wiki/Periodic_table Hypothesis falsified. For pretty obvious reasons, dark matter cannot be made of any elements in the periodic table.
  25. Only if you eliminate all motion. If you have two things moving with a relative velocity then you have two frames of reference, by definition.
