Observable Universe : 8. By the th notation, we would be one Planck Time unit shy of One possible conclusion could therefore be that today we are living within the early part of the nd notation. Use the Gregorian calendar circa where a year is Discrepancies would become quite large at the size of the Observable Universe and the Age of the Known Universe.
Again, using simple mathematics, the distance light travels in one minute is 17,, This difference will be further analyzed. A Planck Time multiple, either 1. We will explore further the calculations for a day, week, month and year based on such a system.
What are Planck Units? What is time? What is a meter? What is length? What is space? Like this: Like Loading Follow Following. Worldviews Are Too Limited Join other followers. Sign me up.

The Planck time is the unique combination of the gravitational constant G, the relativity constant c, and the quantum constant h, to produce a constant with units of time. For example, in during the analysis of the Hubble Space Telescope Deep Field images, some scientists speculated that where there are space-time fluctuations on the Planck scale, images of extremely distant objects should be blurry.
The Hubble images, they claimed, were too sharp for this to be the case. Other scientists disagreed with this assumption however, with some saying the fluctuations would be too small to be observable, others saying that the speculated blurring effect that was expected was off by a very large magnitude.
We have written many articles about Planck Time for Universe Today. The theories that use extra dimensions then have the possibility to use such ideas as representing particles as standing waves on the circumference of the universe in the closed dimensions. Relativity in brief The Planck scale: relativity meets quantum mechanics meets gravity.
The Planck scale combines the quantities used in relativity, quantum mechanics and gravity c, h and G. On the Planck scale, simple ideas about time and space break down. However, the Planck units appear to give absolute scales of length and time. This poses important challenges for Special Relativity, as this page explains, following a brief introduction to the Planck scale. Defining the Planck scale Combining quantum mechanics, gravity and relativity What do space and time mean at the Planck scale?
Defining the Planck scale The Planck length L P is defined by taking the constants of nature and combining them in such a way that their units combine to give a length. Planck's constant, h, has units of joule seconds. Newton's constant G the constant of gravitation has units of N. And the speed of light c has units of m.
This defines the Planck length, which is 1. That's 0. To give you an idea, let's compare it with the size of an atom, which is already about , times smaller than anything you can see with your unaided eye an atom size is about 0.
Suppose that you measured the diameter of an atom in Planck lengths, and that you counted off one Planck length every second.
