Gravitational waves: A three minute guide

It's almost exactly a century since Einstein first predicted the existence of gravitational waves. In this Nature Video we find out what they are, and how scientists are searching for them, in an attempt to prove Einstein right.

What a clear and precise explanation. So easy to follow. Thank you!

[josianamas]

Amazingly clear even to a person completely new to scientific jargon. Really astonishing. Thanks so much for allowing me to understand all this.

[LanIost]

That's an insanely good unintentional transition at 0:06!

[ashwinkumark]

We have confirmed what was conceptualized by Einstein a 100 years ago!

[doctordilanka]

This video is so good that the RIGHT EYE of the guy reporting is experiencing a gravitational wave while the video was being filmed.

This is the biggest news of this century. Last century's was Einstein's theories of Relativity and the Photoelectric effect. Einstein still makes the biggest news hundred years after he's gone

The universe is alive and has a heart pulse... just like all of us :)

[SekitendeJulius]

This is the most elaborate video on this theory so far.

[ThePurestOnes]

I myself made a video explaining the gravitational wave phenomenon in celebration of this enormous leap in our understanding of the universe :D Einstein was such a brilliant guy, all of his theories has been proven correct. Even things he considered mistakes were found to be correct

Hey, I am a student participating in Breakthrough Junior Challenge, may I know whether the footage at the start 00:00 to 00:03 copyrighted? And can I use it in my competition? I saw it in quite a lot of videos.

I have always wondered what evidence we have that gravitational waves can't move faster than light.

[Hayseman-zkdo]

It's amazing what we will build to answer one simple question that really doesn't have much of a significant impact on the world today.

[maasicas]

Objects cause distortion of space AND gravitational waves. Gravity is the result of space trying to push itself back together and gravitational waves are caused by objects moving. Both are caused by mass, but "gravity" and gravitational waves are 2 different things.

[varan]

Sorry if my question is dumb, but aren't light in the laser beams contracting as well as surrounding matter, eliminating all possible differences in travel time that we are looking for?

[itsjustameme]

So in principle one could make negative interference with gravity where the gravity of two massive objects cancel each other out?

[abhinavr]

Amazing to know how simple a concept the LIGO is based on.

[novianovioTV]

Great information. Except if you play the background music at the same level as your foregoround narration they cancel each other out and we don’t have full intake of what you are saying

[berendbeumer]

great time to be alive! Realy made my day

[BIOGRAVITON]

По видимому, так же как и электромагнитные взаимодействия нельзя рассматривать отдельно.То-есть как магнитные и электрические. Подобно этому, я считаю, что и гравитационные поля и био-поля ВЗАИМОПОВЯЗАНЫ!!! Это можно очень хорошо наблюдать в природном "Биогравитоне" -городке на западе Украины - Каменце-Подольском. Там каньон ("минус-масса" камня опоясывает остров с людьми(фауна) - Старый Город) почти замыкаясь на турецком мосту. По всему периметру кольцо-антенна окружена зелёной лесопарковой зоной(флора) создающей разность биопотенциалов. В результате создаётся мощнейший генератор ВОЛН ВЕРОЯТНОСТИ (Де Бройля). И события развиваются очень интересно, непредсказуемо для непосвящённого, а порой чудесно и восхитительно для позитивно настроенных, или крайне трагично для пессимистов. Налицо эффект усиления БИОПОЛЯ!

The fact that there are people in 2017 that believe the earth is flat and deny any evidence proving otherwise astounds me
