  1. Maybe the efficiency refers to greehouse effects ? Methan and other natural gases have stronger effects than carbon dioxide
  2. Maybe reaction is to low to be observed ? For a higher concentration you should try a distillation
  3. Has someone counted the number of topic about time travel ? I think that is one of the most popular subject on this forum. A special section should be created for it !
  4. If two planets were so close they shared an atmosphere there would be a loss of heat energy and planets would get closer until they fell upon one another.
  5. Hi, I'm Emily, I love science and science fiction ! I'm in France.
  6. In this case our atoms could contain small universes ans small people wondering if their universe is in an atoms... We should be more careful with our atoms
  7. We are often traveling in time. Present is only a motion from past to future. No serious theory describes a possible time travel and it only science fiction. You should try this: http://www.bbc.co.uk/doctorwho/dw
  8. The hydrogen bomb could be used if this comet or asteroid is far enough in order to deviate it, but not to destroy it.
  9. According to a rather exotic theory, time may simply stop in five billion years: http://news.nationalgeographic.com/news/2010/10/101027-science-space-universe-end-of-time-multiverse-inflation/
  10. I don't totally share your opinion. Newtonian theory can be completed by other ones. One of these other theories tells that interractions are exerted via elementary particles called bosons. http://en.wikipedia.org/wiki/Boson
