What are gravitational waves? - Amber L. Stuver

In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light that was picked up by the LIGO detector. So what are these ripples in space? Amber L. Stuver explains.

That animation is the greatest on TED-Ed's history. It made me feel the waves and gravity, so sweet.

The bigger the mass the bigger the depression. I'm living proof of this.

[lohithreddy]

The background sounds and animations are simplistic and awesome

[devfrdj]

It's insane that Albert Einstein predicted these waves in 1916. Such a genius

You mean I can send my mixtape out to the whole universe through gravitional waves?

[vijaykumarreddyalavala]

Watch with headphones. What an just wow

[aboodyboi]

the sound design in this video gave me eargasms, I recommend wearing a good headset while watching this, such asmr

Q. What are gravitational waves?

A. "Fluctuations in the gravity coming from the universe are called gravitational waves." (1:33)

I gotta say, props to the scientists that came up with the gravitational wave detection method. It's not scientifically speaking foul-proof, as a number of less extraordinaire factors could still be a cause of it, but the method for measuring these waves did surprise me given it's precision compared to some other grandiose experiments conducted in the field of physics nowadays. Great job to the ted-ed animators and script-writers too, as this was a brilliantly informative video.

I'm fascinated...

When tree falls in a forest and nobody there to hear it, does it make a sound?










LIGO: Yes

[digitronicle]

this video is both visually and audio balanced perfectly to explain the topic. It delivers knowledge with impact.

[tronknows]

One of the best gravitational wave explanation videos. Thank you.

[vemugantitharani]

Thanks for making the complex concepts very simple to understand . Simply phenomenal ted.

[modolief]

Extremely clear and concise explanation, thank you.

[HealthChronicle]

This is a Great Video. I love how all ted ed animations are so nicely done - they make sure the message goes across to whoever is watching, no matter the topic. Getting Inspired by Ted ed over the years we also make ANIMATED HEALTH VIDEOS on our channel. Do check it out if you get the time.

A great video on such a tricky topic. Easy and understandable.❤👌

[taramas]

This animation was.... Just....Amazing!

[Encraftonline]

Thanks ted for one of the simple yet best video out there of gravitational waves.

[gorea]

the sound design in the video is astonishing, props to those who did it
