Towards the search for life on other earths | Sara Seager | TEDxCoconutGrove

Sara Seager examines her pursuit of an Earth Twin. Looking at Earth from the perspective of outer space may allow us to recognize and to identify characteristics of life that may be present in outer space. She offers a look into her "squiggly line" science that may be the key to recognizing Earth Twins outside our solar system.
Professor Sara Seager is a planetary scientist and astrophysicist. She has been a pioneer in the vast and unknown world of exoplanets, planets that orbit stars other than the sun. Her ground-breaking research ranges from the detection of exoplanet atmospheres to innovative theories about life on other worlds to development of novel space mission concepts. Now, dubbed an “astronomical Indiana Jones”, she is on a quest after the field’s holy grail, the discovery of a true Earth twin. Dr. Seager earned her PhD from Harvard University and is now the Class of 1941 Professor of Planetary Science and Professor of Physics at the Massachusetts Institute of Technology. Professor Seager is a 2013 MacArthur Fellow and was named in Time Magazine’s 25 Most Influential in Space in 2012.

    (1:47) "Earth is the only planet we know of that has life on it in our solar system and in the entire universe." A true statement with many implications. One implication is that we have _no basis whatsoever_ to calculate probabilities of life starting anywhere else. Maybe it happens all the time in many places or maybe it happens rarely or _maybe_ it never happens at all. Maybe the life on this planet came from an outside source - outside of this physical universe. Maybe. Does that really seem so unreasonable?

    But life on Earth is all just an accident. There was no design or plan. Its evolution. Even the "elements" that make up all of the matter in the universe "evolved". They weren't "created". Right? Oh wait. How do "elements" just "evolve". And how can something exist without having been "created" at SOME POINT? Never mind. Go back to your "probabilities" and narrow-minded thinking where an unbelievably amazing and "fortunate" series of "accidents" somehow let to Earth and life on Earth "evolving" mixed with "open-minded" thoughts about how such a series of accidents happening "elsewhere" is a matter of "probability". Whatever you do, don't research or even think about the fact that "probability" is "calculated" based upon past, known and observed events, data, etc. Statistics require "data" and "data" requires observation and "observation" requires something to observe and before something can be observed, it has to both happen, be expected to happen and have the data relevant to it recorded and saved and has to be something that has happened and NOT HAPPENED as an "outcome" of a "process" and that "process" has to be everything and anything BUT "accidental" with even the "result" being not a matter of "chance" or "probability" but an identifiable DIFFERENCE that occurred somewhere IN THE PROCESS even if no OBSERVER can see it.

Life can take infinite forms which therefore means infinite possibilities , i suggest you have an open minded mind ...not us

    Just because there are quadrillions ++++ of planets out there, that is not automatically proves that any of those planets should contain any form of life. I am not skeptical, I am just as curious as anyone else, however, one cannot say it for certain what is and/or what is not being out there. We doesn't even know exactly how life was originally formed to become the start of life. Even if the stuff of life can be found all around the universe.

    There very well may be lots of others out there, however, there’s no proof that any such species travelled among the stars to come here. And there was plenty of time for that to happen so the de facto assumption is that it hasn’t been possible due to the insurmountable limitations of interstellar travel. Astronomy will continue to evolve but it’s doubtful that it will get a glimpse of unequivocal signs of sentient life out there.

    The three possible reasons that come to mind why we haven't found any credible evidence of intelligent extraterrestrial life are: (1) one-way communication would be of no practical value to IET, considering that the vast distances/times involved in such communication would be truly astronomical (2) IET life is too advanced to be interested in mere earthlings (3) Unless IET has cracked the mystery of immortality (where time wouldn't matter) two-way communication would be of little interest to IET, unless it has something akin to humanitarian sentiments, which can't be ruled out. After all, most civilised nations (except China, where they skin and boil dogs alive) have organisations such as the SPCA.

    The presenter is unaware of the INTRAVIA HYPOTHESIS which states simply that "Since we have not seen life created, we do not know all the conditions necessary for its occurrence." In addition to planetary conditions (atmosphere, temperature, water, etc), there may be one or more "cosmic" condition(s) necessary which may have existed for only a limited time in a limited space. (The level of background radiation from the Big Bang might be such a "cosmic" condition) Thus, it becomes plausible that there was only one planet with the right conditions AT THE RIGHT MOMENT. Put another way, the Drake Equation may be missing at least one term ... of arbitrarily small value.

Slowly it was upped to where it was estimated that 200 criteria were needed for a planet to support life. Considering that, it wasn't even feasible for life to be here on Earth. Cut the bull, lady.

Why would life elsewhere be like us? They are searching in the wrong places, goldilocks bullshit. No wonder they don't find anything.

Most stars surrounded by planets. Therefore if we believe and preach about God being omnipotent we must accept that He can create life where He pleases. We can't limit the power of God to only one planet.

    Jansci definitely it's her role, as a speaker, to make the viewers interested. She is not talking something new and 90% of the audience already know what will be her summary. therefore smiling and making topic interesting are mandatory.

    Shoeb Adnan I personally think the topic is extremely interesting, whether she smiles or not. Mostly it just looks like she's uncomfortable delivering a speech without a podium in front of her. I'm sorry that it takes a fake smile or cleavage to make a speech interesting to you.

    Brian Bixby I did not mean to say topic was boring. The topic did raise question in my mind and that's why i am here. But I did not like her explanation of topic and presentation style. I understand that she was felling little uncomfortable. But what about her speech preparation. She could add some interesting lines to get viewers attention. Anyway, End of discussion.
