This talk was given at a local TEDx event, produced independently of the TED Conferences. Did you know that gravity can bend space and time, and that clocks run faster at the top of a skyscraper? Martin Hendry describes how Einstein’s theory of gravity shapes our modern world, and how lasers, at the heart of the most sensitive scientific instruments ever built, are opening a whole new way of studying the cosmos.
Martin Hendry is Professor of Gravitational Astrophysics and Cosmology at the University of Glasgow. He is part of a global team of more than 900 scientists leading the search to detect gravitational waves, the ripples in space and time predicted by Albert Einstein and produced by some of the most violent events in the cosmos: exploding stars, colliding black holes, perhaps even the Big Bang itself.
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
So this was before… awesome.
Not a bad prediction. Only about a year off! Good work!!
Thank You. Was wondering about dates & how long it actually took them to detect and confirm their first gravitational wave. Not long at all. So happy for this as funding at least in USA almost demands immediate results.
1:15 Yeah right, what he really means is that it's the most sophisticated grant money scam ever produced, and in a few years time, they're confident they will have rendered a whole new CGI presentation for bullshitting the public.
YES! THE WAVES HAVE BEEN DETECTED!
can we travel on this wave?
This gravity wave stuff is such a crock, just like black holes. Main Stream science should not be considered science anymore, it should be considered science fiction because most of their facts are made up. You can't create facts from theories and thats what these people do now a days. They act like black holes and gravity waves are somehow factual when they have no idea what gravity is . How would they know the difference between a gravity wave , a dark energy wave, a dark matter wave ?. You know something is seriously wrong when science is an expert on black holes and gravity waves when they don't even know what gravity is ? how could anybody thing gravity waves and black holes are factual when they are nothing more than assumptions. why would anybody see a wave and just assume it must be a gravity wave, how do you have a gravity wave with no matter to create it ? Albert Einstein is the reason these guys have a distorted understanding of reality
why does he speak like a hobbit?
Science is amazing… :)
question: how does the gravitational waves deteriorate through space-time? is there a resistance present?
no such thing as gravitational waves, good observation pittiful explanation.
LOL i've been an Elvis fan club member for years.
Thank you sir for such a lucid and simple explanation
numbers measurements and representation of shapes…
(Minute 6) What's the advantage in having mass exert action at a distance on space-time instead of other masses? Exchange gravitons (as you exchange photons in electromagnetism) and you're quite good to go
Probably the entire maths and physics could be explained through one equation and that is y = a sin(x) + c .. because in physics everything is about energy and in maths everything is about the numbers and measurements.. like y= a if x = 0 and c = 0.. and substituted with different values you could generate the numbers and so on and so forth..
Am I the only one who really likes his accent?
I myself made a video explaining the gravitational wave phenomenon in celebration of this enormous leap in our understanding of the universe 😀 so hyped about this
