    Frame Time
AI Thread Summary
The discussion centers on the concept of the shortest measurable time duration between events in the universe, exploring whether there is a limit to this duration and its relation to Planck's constant. It highlights that the shortest time frame, derived from the Heisenberg uncertainty principle, is theoretically very small but not practically measurable. The conversation delves into the implications of Planck's constant on defining events in the universe, suggesting that events could be viewed as vibrations with specific energy levels. Participants express a desire for deeper understanding and further exploration of these concepts, indicating an interest in advanced topics like wave equations related to the universe's energy. The discussion also touches on the capabilities of current measurement devices, such as attosecond clocks, which are at the forefront of measuring extremely short time intervals. Overall, the thread emphasizes the complexity of measuring time at quantum levels and the ongoing quest for knowledge in physics.

What is the shortest time duration that one particular frame can exist?(between two interval of universe) or what is the shortest duration between two unique events in the universe?

Has it got limit?

Is it measurable?


If it is , to what extent it is measurable?

What's our capabilities ( devices we got) to measure them?

is this shortest time frame has something to do with Planck's constant(h)?

Thanks in advance for your valuable replies.

\frac{\hbar}{4E}
where E is the total energy of the universe. I forget if the factor in the denominator is supposed to be 2 or 4. Anyway, it is a consequence of the Heisenberg uncertainty principle. This is a rather short amount of time because the numerator is very small the the denominator is very large. It cannot be measured in any practical way.
 
Thank you for reply. That was helpfull.

Can you tell how can we define the time frame in the light of this Planck's constant.

can we say an event in universe is a single vibration consisting some certain energy(again in terms of Planck's constant).

I hope we get a physicist involved here because I am not sure of the answer. Theoretically, though not practically, it may be that you could come up with a wave equation for the state of the entire universe, I'm not sure. If so, it would contain information about the energy in the universe, but there would be some uncertainty in the amount, meaning it would give you a range of values rather than a single value. If you were to actually measure the energy of the entire universe, the result would be one of the numbers in the range, but before you make the measurement, you have no way of knowing which one you'll get. However, I have no idea if you can identify events with vibrations of this wave equation.
 
Hyperspace,

You may be interested in reading: http://www.rdmag.com/News/2008/07/Attosecond-clock--takes-measure-of-quantum-tunneling/"

In the not too distant future I was planning a post on it, but have yet to do the hard research necessary to make it meaningful to a layman (and others like myself).

You beat me to one of the more tantalizing aspects of my digging into it.

I hope you find it useful, and that it sparks more meaningful questions and discussion by all who contribute here.

Rhody... :wink:

Thanks for post. I will definitely going to read your link.

I am an electronics engineering student , yet have great respect and passion for physics.

I have lot of questions and confusions(ocean of it) , and I am trying to quench my thirst.

The people like you will be beneficial for me in this forum.

Last question- are you physics student or became already physicist..?

THank you!

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
