• Can a star sit barely on the edge of being able to support fusion such that it will actually oscillate through fusion cycles?
• How much time passes between when something happens in front of us, when our eyes receive that visual information, and when our brain processes it?
• Did the advent of the Nuclear Age have a spectroscopic effect on our atmosphere if viewed from another solar system?
• Does the rate of genetic mutations increase as a result of environmental pressure? If so, is this rate change selected through natural selection or does it affect individual organism as part of some feedback loop with the environment?
• how does cells stick together?
• Is there a consensus on SV40 and Polio Vaccines?

Can a star sit barely on the edge of being able to support fusion such that it will actually oscillate through fusion cycles? Posted: 28 Sep 2018 04:35 PM PDT Can a star sit on the edge of being just large enough to support fusion but too small to support continued fusion? Could a star be massive enough to ignite fusion but then the fusion pressure is powerful enough to push against gravity so that it stops fusion until gravity collapses the material again and fusion restarts? If such an oscillating star is possible, would the cycles be in seconds, minutes, hours or longer? submitted by /u/Stuck_In_the_Matrix [link] [comments]

Did the advent of the Nuclear Age have a spectroscopic effect on our atmosphere if viewed from another solar system? Posted: 28 Sep 2018 09:38 AM PDT I have read about the effect that the detonation of atomic and nuclear weapons has had on the atomic makeup of certain materials, such as steel. Would our atmosphere demonstrate a discernible effect from the atomic detonations that would be visible from a solar system that is several light years away using our own spectroscopic technology? If so, would this indicate evidence of intelligent life, or can this effect be replicated naturally? submitted by /u/Pulfe [link] [comments]

Is there a consensus on SV40 and Polio Vaccines? Posted: 27 Sep 2018 03:48 PM PDT I'm talking to someone on Facebook in regards to Simian virus 40 and the polio vaccine. I used to be in immunization and allergy specialist, this was a long time ago though and maybe I am outdated with my education. However, this person on Facebook is adamant that SV40 is still an ongoing and potentially carcinogenic issue for people. Am I incorrect in my recollection that this has already been confirmed as a non issue? If you are extra knowledgeable in this field a little extra elaboration would be nice if you wish... submitted by /u/Gigantkranion [link] [comments]
