AI Thread Summary
The discussion centers on the concept of "Amplitude Death," which raises the question of whether everything in the universe is constantly vibrating due to its natural frequency. The original poster, Steve, wonders if it's possible for something to stop oscillating entirely and what the implications of that would be. A participant challenges the notion of universal vibration, explaining that an object only vibrates when acted upon, such as being pulled or pushed. The conversation highlights the complexities of oscillation in physics and the conditions under which it occurs. Overall, the thread explores the relationship between natural frequency and the potential for cessation of vibration.

Hi all,

Posted this in general as I think my question could span a number of physics fields.

I was doing some work on Turbulent flow this evening and whilst on Wikipedia I got myself reading links after links until I came across a link called "Amplitude Death" and this got me thinking.

I understand that everything in the world has a natural frequency and therefore everything is vibrating.

The question that popped into my head was.. "Is Amplitude Death actually possible? Can something stop oscillating/vibrating, if so what would happen?"

Just curious, but I thought this forum would be the best place to ask!

Thanks
Steve

Huh? Where did you get such an idea? "Natural frequency" of a spring, for example, is the frequency at which it will vibrate if you pull it or push it and then let it go. If you DON'T pull it or push it it doesn't vibrate.
