A TED two for History of the Universe in Sound: and Sound the Universe Makes:

In summary, the conversation is about the use of sound to explore and understand the universe. Honor Harger and Janna Levin discuss the various sounds that can be heard in space, including the ringing of space, the sound of a black hole consuming another, and the possible sound of the big bang. They also mention the incredible sounds recorded by the Voyager spacecraft as it passed by planets in our solar system. These talks can be found on TED's website and are open to the public.

Ringing of space... then banging on space as a big black hole gobbles a small one...the sound of the big bang... or possibly the sound of multi-verse big bangs...

Enjoy...

Very cool. I really enjoy these TED talks. Thanks Rhody.

I just realized these are talks I'd like to see in person, so I looked. Seems they're open to the public and listed on their site here: http://www.ted.com/tedx

They have an interactive map so you can find talks going on near you and get tickets. I wonder if they sell beer at these events?

Thanks for the talks!

Sound from Vela Pulsar. It's like a cosmic rave party!

Also one could find all over youtube similar videos of electromagnetism-turned-sound by the Voyager spacecraft of planets in our Solar System. Most of them could be taken as art! Although I'm not sure how authentic they are. I just don't see how we could receive such clear signals from Voyager being so far away. Maybe we have enough information to reconstruct the signals back on earth? Jupiter as an example below. It's just too good to be true!

1. What is the significance of sound in understanding the history of the universe?

Sound plays a crucial role in helping us understand the history of the universe. It allows us to study the properties and movements of celestial objects, such as stars and galaxies, which emit different types of sound waves. By analyzing these sound waves, we can gain insights into the composition, structure, and evolution of the universe.

2. How does sound travel in space?

Contrary to popular belief, sound cannot travel in the vacuum of space as there is no medium for it to propagate through. However, in certain scenarios, sound waves can travel through the ionized gas between stars, known as the interstellar medium. These waves are typically low-frequency and can reveal important information about the universe's magnetic fields and other physical processes.

3. Can we hear the sound of the Big Bang?

No, we cannot hear the sound of the Big Bang as it occurred over 13 billion years ago, and its sound waves have long since dissipated. However, scientists have been able to detect an echo of the Big Bang in the form of cosmic microwave background radiation, which is a type of electromagnetic radiation.

4. How does studying sound in the universe help us understand Earth?

Studying sound in the universe can provide us with valuable insights into the physical laws and processes that govern the universe, including the formation and evolution of stars and galaxies. This knowledge can then be applied to better understand and predict phenomena on Earth, such as earthquakes and volcanic eruptions.

5. What is the role of technology in capturing and analyzing sound in the universe?

Advancements in technology, such as radio telescopes and other specialized instruments, have allowed scientists to capture and analyze sound waves in the universe with greater precision and accuracy. These tools have also enabled us to detect and study sounds that are beyond the range of human hearing, providing us with a more complete understanding of the universe's sonic landscape.
