The most mysterious star in the universe | Tabetha Boyajian

  • Published: 29 April 2016
  • Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

    How do we know other solar system planets circulate
    in the same plane that we are observing from? 
    Are we assuming all solar systems rotate in the same plane  we are in? 
    Lets just say this star rotates in the same plane of sight, there could
    be much debris (not in planetary form rotating in an elliptical pattern,
    sometimes crossing in our line of sight and then moving out.  Or mutable planets crossing our path near the same time dropping the density.

      If we found that by barely looking, imagine what else is out there giving how big the universe is. It's impossible we are alone. Remembe, just because god didn't mention aliens in the bible doesn't mean they don't exist. its all his plan taking place in his time for his reasons.

          What’s more plausible? Intelligent life on other planets or thousands of space rocks coincidentally flying in front of a star at the same time and it happening many more times??

              Yes, Ms. Tabetha Boyajian, is right, those are structures or shall we say CRAFTS ... the Kepler just witness a massive rescue on a planetary civilization or maybe few planets on Taby's Star System ... and who knows? we may also about to meet our planetary cousins.

                      Its proven that aliens already have "engines" that do not produce heat. So this is very possible.

                        All the theories seemed to be tied to masses associated with the gravitational influence of the star. Perhaps the light is being blocked by gas or dust clouds that are passing slowly between us and the star. They would probably be closer to the star than to us, but still not under the influence of the star's gravity. Their shape and density could be variable enough to explain the asymmetric effect on the star's light intensity.

                          Why cant it be stuff going in front of the telescope - near the telescope - not near the star? Looks to me more like cloaked space ships investigating our telescope...

                            WHAT IF : due to the harm industries and nuclear power plants etc did to us, to earth in some few centuries, it affected our body and minds which made us look alien-like. now, till that time, in those 400-600 years, (this is how much time it will take all that to happen) so we would have developed all the kinds of devices and machines of which we always dreamt of, they now existed in future. now these alien-like creatures, who our generations turned into, they now time traveled in our time to tell us, to stop all the wrong steps which made our next generation look like aliens. so now these were the aliens who we always wanted to discover, they're the one who always kept on sending signals and to connect with us to tell us stop all that we're doing due to which they became THE ALIENS and they're our future generation itself! just their body and minds affected by the radiations, development and effects of industrial and nuclear and all. thoughts?

                                      A giant collusion would produce a huge amount of dust. this would block the light from the star like a haze instead of a single object and would create a different shaped light curve. Also, the dust would be glowing in the infrared because of the heat from the sun and the collision, and so the system would look brighter at infrared than it should, and it doesn't.

                                              @warrax111 thanks for your comment. When i came across this flat earth thing, i thought the ssme as you. And made it my mission to debunk what i thought was nonsence but after a few months i could not deny that the earth is flat. Once your able to shift your perspectiveit is clear as day. Please actually watch some earth vids with a open mind. PEACE.

                                              +Darren Bailey Omg, you are a flat earther? You basicaly degrade human science and human intelligence. I admit, space program and science take lots of resources. But not observation. Actually, real missions. The hubble telescope and other telescope are actually good stuff. It helped to deny lots of nonsense, that religions was lying to people over years.
                                              But you are degradation of human intelligence, until you believe flat earth. You flat earthers were basicaly destroyed in every decent discussion by scientists, or people with intelligence. And your theory was debunked many times. Dont be a blind sheep. There is lots of evidence all planets are round.

                                                  Consumption of a planet
                                                  In December 2016, a team of researchers proposed that Tabby's Star swallowed a planet, causing a temporary and unobserved increase in brightness due to the release of gravitational energy. As the planet fell into its star, it could have been ripped apart or had its moons stripped away, leaving clouds of debris orbiting the star in eccentric orbits. Planetary debris still in orbit around the star would then explain its observed drops in intensity.[74] Additionally, the researchers suggest that the consumed planet could have caused the star to increase in brightness up to 10,000 years ago, and its stellar W.T.Flux is now returning to the normal state. :PM:As the Low mass star began is consumption of the metallic core, the increase of light permeated the sky in a fragmented but brief process.
                                                  :PM:You have to remember The universe only takes what it needs. It was probably just hungry at the time and went night night.

Very misleading and confusing, how do you get three letters from four letters which is actually a much bigger word/idea.. be safe everyone.
