The most mysterious star in the universe | Tabetha Boyajian
About | Information | History | Online | Facts | Discovery
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.

could it be a black hole distorting the star's light?
-
These are solar surface events not transit just huge dark spot irregularities as this particular star
Is unstable. -
ok first not saying it is aliens. but if a race got that advanced to build a Dyson Sphere to harness more energy then they would have all ready known that heat is another energy source and instead of letting that heat energy escape and be wasted they would have built in to the Dyson system a method of capturing and using that heat energy which means we wouldn't find the heat signature of it do to the heat being used

its dysonsphere

Science is the search for truth and so scientists must of course look for the simplest answers before invoking fantastic explanations like aliens, but they need to be smarter about how they go about this. Humans have a hard time supporting things unless they have a direct benefint,or it captures their imagination and you only need to look at the dismal funding of NASA and science in general to see the truth of it. The scientific community dismisses those things that easily captures the publics imagination and thereby misses a great opportunity to increase not only interest in science, but important funding and support.

Very rich aliens because they can build this one. They have a lot of galactic dollars.

Boy Kepler Mission was so joyful and mesmerizing! I love every single Kepler data #NASA shared with the world! I wish if there is a similar mission in the near future, and don't get me wrong, I know that JWST is the latest and greatest, but the technology and projections of those two observatory missions are distinct and different in many ways, Kepler mission is somewhat uniquely different!!

This is the second TED talk that I've watched this week that has not only disappointed me, but actually slightly angered me. Why? Because it's just bad science. It's unbelievable that she starts the lecture by quoting Carl Sagan - ''Extraordinary science requires extraordinary evidence'' - then proceeds to offer us not extraordinary evidence but sci-fi style imaginings. That's not science. She then goes on to explain how she opened up the best-guesswork to the astronomic hoi-polloi, who offered all kinds of vivid imaginings including alien warfare. (The heat residue of which by the way would have been very evident, so, come on.)
She tells us to ''imagine'' an alien civilisation, who, being far advanced compared to us, would have exhausted energy resources. Why? Why would they have exhausted their energy resources? No ''advanced'' civilisation would do this. But she then goes on to explain a theory based on that ridiculous starting point.
This is the worst thing about some modern ''scientists''. Instead of looking at available evidence and slowly building up to a theory, they start with their desired theory and try to make the evidence fit. Imagine you have a jigsaw puzzle, but you have lost the lid. It might take a long time but you could eventually put it together and find out what it is a jigsaw of. But what many scientists attempt to do these days is decide what they want the picture to be and try and jam the pieces in to fit their hypotheses.
This woman like many other ''scientists'' today remind me of Fox Mulder from The X-Files who had a poster in his office of a UFO with the caption ''I Want To Believe''. -
Lots of people are saying they believe it's planets but the data showed that the irregular pattern within the light dips ruled that out..... unless there's a triangular shaped planet in which case I'm packing my bags and heading out to find it
-
it's a big piece of swiss cheese
-
Dark Star
-
the Electric Universe theory and plasma physics explains this star easily, as well as all other unexplained or anomalous discoveries...
-
how many alien is a question...OK. thanks
-
It's just an intergalactic talent show and we're seeing the remnants of a planet that was DISQUALIFIED! SHOW ME WHAT YOU GOT!
-
No one thought about the possibility that there may be more than one planet rotating around the star and we observed it when there was a cluster passing in front of it?
-
Could it possibly be Donald Trump's hair?
-
i want to beleive
-
a school of very large space whales...next question please!
-
An alien race that ran out energy built a Dyson sphere to take it from sun!!
Yeahhhhhhh where they found energy to build the Dyson sphere? -
worst shill ever
