The Dark Universe Through Einstein's Lens

One of the most surprising predictions made by Einstein's theory of relativity is that light doesn't travel through the universe in a straight line. The gravitational field of massive objects will deflect the path of light traveling past, giving some very dramatic effects. We see multiple images of quasars, galaxies smeared into arcs and circles and magnified images of the most distant objects in the universe. This talk will explain how gravitational lensing was first observed and discuss how scientists use this phenomenon to study everything from exoplanets to dark matter to the structure of the universe and the mysterious dark energy.

    Really enjoyed hearing Debbie Bard. Her enthusiasm for her work is quite evident. Loved the subject matter (dark)! :-)

    Thanks, it was excellent!, slight British accent did not need subtitles ;-) For first time I realise that it could be cool and not so heavy. Classic subject was wrapped in new inputs, like a Computer Simulation that was well presented!

    Started at 7 from work, only to realize that I took the wrong exit to 92 east Hayward. It was 7:30 by the time I came back to San Mateo :/. next time.

    Ok everyone, the red cap is MIA. I'll be wearing a black cap that says FBI on the front. I'll arrive about 7pm and sit to the left as you walk in, about halfway down. It's not a good place to save seats but we can at least find each other.

    Hi Edward,
    Will the group be sitting together? Do people go out for coffee afterwards for post lecture discussions?
    Thanks!

      These events usually attract a crowd! Arrive early if you can. In the past I've worn a red baseball cap so those who want to meet up can. Edward, I'll do that this time if that's ok.

      he SLAC Lecture series is designed for the public so should be The audience will likely include geeks asking technical questions. accessible.

    • Elisa

      Whoa, hit send too soon! Bottom line,, it's designed for amateurs but those with more knowledge attend, too.

    Hi
    Does anybody know about any electric car charging stations (e.g. Blink) on Loop Road of the SLAC National Accelerator laboratory? Otherwise I will walk up 2 miles from Stanford Main campus - it is healthy ;-)
