Astronomy's New Messengers
About | Information | History | Online | Facts | Discovery
Marcia Bartusiak joins Kip Thorne, Laura Danly and Rainer Weiss to demonstrate how two observatories on opposite sides of the country, called LIGO (Laser Interferometer Gravitational-wave Observatory), may open a new window on observing the cosmos—one based not in light but in gravity. Scientists have embarked on this joint experiment, seeking whispers of far-away violence—like the collision between distant black holes—rippling through the cosmos. It’s taken nearly a century, but technology has finally caught up to Einstein’s brilliance. His 1916 General Theory of Relativity predicted the existence of gravitational waves—undulations in the very fabric of space and time—and LIGO researchers are now poised to detect them.

Jaysus, guys. You had KIP THORNE on your panel, but thought it was better to spend 15 minutes reviewing the most elementary facts of gravity, well understood in advance by your average ten your old??

The "double slit experiment" is the common cold of the physics world. It shows light functioning as both a wave and single photons, which can't be explained. It tempers my excitement about a lot of these theories.

Let's all giggle and talk like children.

"AeeEe".

They can hear a pin drop in every house in north Korea. And every comb that goes throw everyone's hair.
-
we need to focus on our planet and each other then the universe understand
-
agreed niel tyson is a big arsehole
-
These World Science Festival talks are like a breath of fresh air in the otherwise cesspool of crap produced by the likes of National Geographic, the Discovery Channel, Neil Tyson, etc.... Thank you so much for this!!

As people already stated in the comments:
- 12:31 freaking minutes of introduction, wth? -
February 2016, Gravity waves discovered, there might be a planet 9 somewhere beyond the Oort cloud... we live in an amazing time period...
-
And about 1 year later, LIGO detects gravitational waves! Science is friggin amazing. :)

when i hear hollywood or movie put into a sentence where it didn´t belong according to conversation i say bye bye

the universe is electrified. gravity is the pressure from surrounding magnetic fields. gravity seems to push 90 degrees to any magnetic field line. so the magnetic field lines sustain the gentle push by imparting inertia onto an object with mass. if a massless particle such as a photon passes through. it gets more electrical energy imparted onto it to self sustain and move unhindered. some photons hit he lines with the same charge nd instead follow the lines indefinitely or until a weak spot releases the photon. gravitational lensing.
im speaking shit. but its an idea. -
great show, but when we finally get to the last panelist the host talks all over him. rude
-
KIp Thorne is one of very rare people that can explain things well. Too bad he has some disability in his speech. Nevertheless he is a rare jewel on youtube for gravitational topics.
-
I enjoy this "Shows" immensely ....so few of them going around.....some times one is to busy w/every day living that one loses track of the fact that stuff like this is out there .....ready for us to enjoy it.
I like to thank everyone involved on developing these programs and those who ensure they get to us....
Thanks!!......Gracias!! -
he's an android.

i tried to understand Andrea's explanation but was foiled by her sexy red dress and long legs: xlnt calves, thighs that shine out, a beautiful woman sighs

Freeman Dyson has shown an equation proving that LIGO will never ever detect gravitational waves/gravitons.A waste of money and a huge mistake on behalf of the folks behind the project.
