[Request] Cell Division in the Planck Time - how long would it take to form a new body?

1 Upvotes

As the title says, if your cells would split in the planck time 5,391247 ⋅ 10⁻⁴⁴ seconds and it starts with just a single one cell (not already a formed body with a lot of cells), how long would it take to form all cells of the average human body?

The body has, depending on the source, 30-36 trillion cells, let's just go with 30 trillions for the calculation here. Let's ignore the different forms of cells and different parts of the body in this example

I'm very bad at math, but does it not even become much faster with splitting of the cells, because after the first one, there are two cells and from there on, there are four cells and so on?

Thanks for any replies!

[Request] What is the computational load of the observable universe?

In other words, how much computing power would it take to compute the exact position and orientation of every elementary particle down to the Planck length at a refresh rate of 1 per Planck time?

Edit: People are getting hung up on the simulation analogy so I removed it

Marked with Spoilers for Fire Emblem: Fortune's Weave. The massive... thing in the middle there is the true body of the progenitor goddess, Sothis. I was wondering if there was any way from this shot to work out how big she is. For context, the two men in the foreground are orbiting the planet in a huge space ship. This is the best shot of her and you might as well use the Earth for scale, since there are a ton of hints the planet is supposed to be Earth-like.

That is a pretty mind-blowing statistic, if true.

A 15 kg caracal launches vertically and reaches a takeoff velocity of 7 m/s. Assume its centre of mass accelerates uniformly from rest over a vertical distance of 0.50 metres.

Using Newton's laws of motion, estimate its average upward acceleration and the average net force acting on its centre of mass during takeoff.

Then calculate the average upward ground-reaction force required to produce that acceleration, including the force needed to counteract gravity.

How would the results change if the acceleration distance were only 0.25 metres?

How powerful would a humans legs need to be in order to do this?

Assume they are 80 kg person.
