  1. Well you certainly have spent an inordinate amount of time critiquing others posts and very little discussing the articles that were asked for and were given. Heres another. https://www.scientificamerican.com/article/are-we-living-in-a-computer-simulation/ Please let us know what you think. Oh and just for fun heres a flash fiction story on the subject. Everyone please read its really short and more interesting (so far) than this thread. http://dailysciencefiction.com/science-fiction/virtual-reality/philip-apps/the-no-sick-box
  2. Well I can't call you wrong. And I didn't read most of it for the reason you stated.
  3. As Strange said they are still not electromagnetic. We wouldn't need LIGO if they were. BTW the waves are not LIGO either.
  4. I think he probably will do some time. Trump will probably not although it does look like impeachment looms. One would think Trump insulated himself well enough to stay out of prison but he continues to suprise me. The other day he went after Joe Scarborough for no reason at all. Now Joe is claiming someone in Trump's inner circle said Trump has dementia. Which would explain some things.
  5. Rut roh it's getting hot up in the White House. https://mobile.nytimes.com/2017/12/01/us/politics/michael-flynn-guilty-russia-investigation.html?referer=http://www.google.com/
  6. Here LMGTFY. https://en.m.wikipedia.org/wiki/Simulation_hypothesis BTW this is a very old idea some Mayan texts indicate that they thought we exist in the dreams of gods. And in the 3rd century BC Zhuangzi Zhou wondered if he was a man who dreamed of being a butterfly or a butterfly who dreamed of being a man. Also Houman Owhadi, Tom Campbell, Joe Sauvageau and David Watkinson have proposed some experiments. https://arxiv.org/abs/1703.00058 As for me? Much like the question of free will I can't see what difference it makes so its just easiest to assume reality is real. Read the first link first its a pretty comprehensive overview on the subject.
  7. The Initiative for Interstellar Studies (i4is) is planning to build a probe to chase down Oumuamua and make some closeup observations. According to the i4is website they are a dedicated team of volunteers, committed to the vision of seeing interstellar flight achieved in the very near future. Sounds impossible to me. The fastest thing ever built by man is the Voyager 1 and it is travelling at 17 km/s. Oumuamua is moving at 44 km/s and it already has a large head start. https://i4is.org/i4is-announces-project-lyra-mission-a2017-u1-interstellar-asteroid/
  8. I really enjoyed the articles. I like how Cornell ranks theirs beginner, intermediate and advanced. But how could you forget xkcd? https://what-if.xkcd.com/49/ He mostly focused on the positives. Maybe you learned that from Phil Plait. He has a really good article on "stars that you see that don't exist anymore." http://www.slate.com/blogs/bad_astronomy/2013/08/13/are_the_stars_you_see_in_the_sky_already_dead.html
  9. A couple of more. I can never really get enough lol. So the first vid explains why the Milky Way might reside in a cosmic void. And the second one is a different take on the vid Mordred posted.
  10. I would see a doctor too. Have you lived in the same place all these thirty years? Wikihow has a pretty good page on how to get rid of spiders and keep them gone. https://www.wikihow.com/Kill-Spiders I particularly liked these suggestions.
  11. Very cool. Thanks Strange! I shall now attempt to embed a youtube video. It has some animations of Oumuamua plus a few words from Paul Choda who is manager for NASA's center for NEO studies and Kelly Fast (nice name for an astrophysicist) who is program manager. Paul says "we have been waiting for the discovery of an interstellar object for decades." Ok that was a lot easier than I thought it would be.
  12. Wow thats crazy awesome! Thanks so much for turning me on to this. I watched on my phone but will definitely watch on tv later.
  13. Professor Arjun Berera from the University of Edinburgh’s School of Physics and Astronomy has authored a paper suggesting that life on earth may have been seeded by cosmic dust streams. And not only that but Earth may be seeding other planets in the same way. A link to the abstract. https://arxiv.org/abs/1711.01895 So apparently we are stardust transported by cosmic dust. Heres an article on the paper. http://www.astronomy.com/news/2017/11/life-in-dust Now click on the link above and go look at the picture of a tardigrade. Please!
  14. Not me but... ...somebody did http://www.astronomy.com/news/2017/11/interstellar-asteroid-is-a-quarter-mile-long-red-beast
  15. @studiot said @sci-man let us know how the experiment turns out.
  16. Heres a more recent article suggesting the fossils are closer to 32,000 years old. https://phys.org/news/2017-09-dating-neanderthal-vindija-cave-older.html
  17. Home science tools seem to have a good selection. https://www.homesciencetools.com/chemistry/chemistry-kits/
  18. Bad news indeed if it happens. https://www.reuters.com/article/us-usa-internet-exclusive/exclusive-u-s-agency-to-vote-to-repeal-net-neutrality-rules-fcc-chief-idUSKBN1DL21A
  19. Interesting and some nice pics as well. I think I have observed a similar phenomenon just not as dramatic. I spend a week at the same condo in Destin Florida every summer for the past 25 of them. Sometimes it is very shallow many meters into the ocean and sometimes it drops off very quickly.
  20. Yep thats why when it was spotted dozens of observatories turned their telescopes on it.
  21. Your welcome. I'll probably have a little more to say and possibly more questions after I think about your article a little more. Honestly, with regard to the two threads I think you are referencing, after page three or four I don't know why you bothered. Carl Sagan ignited my interest many years ago with his series of books chronicling the adventures of the pioneer probes almost thirty years ago. I am still very much hooked. As I don't have the formal training I rely on people like you to explain the finer details of the amazing discoveries being made these days.
  22. Thanks for the replies they really help. Ok I guess we are just going to have to wait for more observations.
  23. To add to what Prometheus said the prefix xeno means foreign. And make the moon pay for it.
  24. Well I read the article and it was a good read but I don't think it really addressed why black hole mergers might not have an EM component. In fact the article states that several researchers feel that there was one but their findings cannot be confirmed. He concludes with four bullet points that the evidence seems to suggest that if black hole mergers do have an EM component , it's one that's: incredibly weak, that occurs mostly at lower energies, that doesn't have a bright optical or radio or gamma-ray component, and that occurs with an offset to the actual emission of gravitational waves. He also dosent get into the why of the offset. I dont understand that either. The article left me with another question. Sorry. I'll repost your link to (hopefully) avoid confusion. https://www.forbes.com/sites/startswithabang/2017/06/08/newest-ligo-signal-raises-a-huge-question-do-merging-black-holes-emit-light/#680a220147d9 Did he just say something came out of a black hole?
