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

[Request] The federal budget allocates roughly 10 times more per capita to Americans over the age of 65 than to those under 26.
That is a pretty mind-blowing statistic, if true.

[Self] Lottery Probability
My husband and I have been doing these tickets lately, as the are super fun to scratch! I know we are not going to win, but I was wondering what the probability of getting a bingo - a big one (>$1000) off a card like this?

[Request] Would the cube really be millions of degrees?
Also would you be full? What would happen if you tried to eat it?
I suppose that first question could be disregarded if the grilled cheese cube is in fact millions of degrees lol
Feel free to answer it anyway tho!

[Request] How powerful would a human legs need to be in order to do this?
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.
