Deck of Cards and Planck Time?

Click For Summary
There are significantly more ways to rearrange a single deck of cards than there have been Planck times since the Universe began, with 52! approximating 8.066 x 10^67 formations compared to about 5.053 x 10^61 Planck times. A Planck time is defined as the duration light takes to travel a Planck length, which is 1.6 x 10^-35 meters. The discussion highlights the vastness of possibilities in card arrangements and raises questions about their implications in quantum physics. Additionally, it notes that the age of the Universe in years is comparable to the current global population, suggesting they may equalize in the near future. This emphasizes the extraordinary scale of both time and combinatorial possibilities.

Deck of Cards and Planck Time?

This is truly unbelievable. I've checked my work multiple times, gotten it checked by others, and still the same answer remains.

There are more ways to rearrange a single deck of cards than there have been Planck times since the Universe began.

Number of formations of a single deck of cards:
52! = 52 x 51 x 50 x 49 ... 3 x 2 x 1
52! \approx 8.066 x 10^{}67

Number of Planck times (tp) since the Universe began (assuming the Universe is approx. 16 billion years old, which is generous):
(1 x 10^{}44) x (60) x (60) x (24) x (365.5) x (1.6 x 10^{}10) \approx 5.053 x 10^{}61

(tp in a sec)(sec in min)(min in hr)(hr in day)(day in yr)(yr since singularity)

8.066 x 10^{}67 > 5.053 x 10^{}61

Keep in mind, a Planck time is the time it takes for light (in a vacuum) to travel a Planck length (1.6 x 10^{}-35 metres.

Now, think about how many possible games (that is: entire games) of chess there are.
 


Are you trying to make a point about something related to quantum physics?
or just stating the vastness of possibilities in a deck of cards?
 


Another "unbelievable" fact:
The age of universe in years is of the same order of magnitude as the number of people on Earth. They will probably become equal in the next 100 years or so.
