Feb 29 at 16.30 UTC: hangout on the discovery of gravitational waves

On February 11th, 2016 was announced the discovery of gravitational waves by the LIGO and Virgo collaborations. We organize the Gravitational Wave Fiesta in Paris for this historical occasion. In order to allow everyone to participate, we hold a special hangout on February 29 at 16:30 GMT.

Ask your questions!

You will have the opportunity to ask your questions about this exceptional discovery.

This Google Hangout will be streamed live on YouTube and Google+ Hangouts for approximately 60 minutes, where you can follow the questions and answers live.

If you are not among our 80 lucky guests who will be present in Paris for the Fiesta, we encourage you to ask your questions and we will select the most popular ones to ask our guests during the Hangout.

There are three ways you can do this:

  • You will be able to send questions and comments before and during the event by submitting them in the Google Hangout Q&A chat window (if you have a Google account).
  • You can send us questions to our Twitter account @Gravity_Paris, using the hashtag #FLGravity.
  • If you are registered to the first session of the Gravity! course on Futurelearn,  you can leave your questions or comments in advance on the discussion of step 5.12 of the course .

What happens if I can’t watch the live Hangout?

Don’t worry!  A recording of the discussion will be made available after the live event finishes. You will be able to access the recorded video after the event right below.

Will loading the Hangout mean I appear on camera?

No, you will just watch the live stream like any other video (though Google users can submit comments via the interface).

Is a Google account required to view the Hangout?

No, you can watch the Hangout without logging in to Google.

    Q:- How discovery of gravitational waves helps in future development of human being ? is this discovery helps us to rethink on the different laws & principles of Physics?

    • Hi,

      gravitational waves allows us to see events in the sky that cannot be seen with other means, for example black hole merger, the inner structure of supernovae, etc. At the same time, analysis of gravitational waves can provides us with some new information about general relativity and the nature of gravity: Is General Relativity the correct theory of gravity in strong regimes? Do gravitational waves travel at the speed of light? And as any other science discovery in the past, there is the unexpected…

    What is the most optimistic launch date for eLISA?

    What might gravitational lensing of gravitational waves tell us?

    I SO appreciate your hangout this morning discussing the ramifications of the recent findings on gravitational waves. I would like to suggest that the names of the participating lecturers be printed on the screen so we may know them. They were introduced but it was too difficult to catch last names, especially.

    I am particularly interested in knowing the name of Marco, who represented LIGO. I would like to contact him as I am very interested in being one of the citizens whose computer is used to download and analyze LIGO data. I hope you can help me contact him or the organization that sets up the computers of the people whose computers can be used for downloading data. Thank you!

    • Hi Judy,

      this is Marco (Cavaglia). Thanks for your comment, and for watching the hangout! You can find all information on Einstein At Home here: http://einsteinathome.org/ Being able to “use” home computers for our data analysis really helps us a lot. Maybe your computer will find a gravitational wave in the future? 🙂 Cheers
      Marco
