How did matter in the universe start moving in orbits ? How do things start spinning ?

The big bang theory says that matter went straight away from a central point.

Is that sufficient to create orbits ?

Maybe it's not a big bang and more like a big slingshot.

This orbit thing also looks fractal to me.

Galaxies, solar systems, planets, moons, atoms. And are there orbits smaller or bigger than that ?

A few months ago, I noticed that the forces and movements currently described as a set of straight lines can also be described as a set of orbits.

If someone throws a ball, it can be described as (at least) two lines : one forward and one towards the ground.

But it could also be described as an orbit around the earth with slight orbital influence from nearby and less nearby objects (other balls and the moon for example).

I wonder if they are still useful now that the water in bathrooms is no longer grounded.

The supply lines are made of PEX and the drains of ABS.

This means that, if you were touching the live wire and water at the same time, the outlet would not trip because the water is not connected to the ground (and not completing the circuit).

Oh wait, now that I think about it, some electricity can flow through the water in the PEX pipe. But is that enough to trip a GFCI outlet ?

I find it annoying that I can't find a large, high-resolution, non-smart TV.

There are none at Costco and the ones on Amazon are too small.

Even if I buy a Smart TV and not connect it to Wi-Fi or Ethernet, it is not inconceivable that it would upload everything through LTE or 5G.

Me and my dad cut and bent some sheet metal to replace flashing around the basement access door.

We had some holes at the bottom of the door.

Me and my dad glued some sheet metal to cover the holes.

These days, I am watching Hell's Kitchen.

(I watch multiple series at a time and switch between them)

I am suspecting that the contestants specify the ingredients they need in their signature dish.

In season 4, Louis Petrozza used a pumpkin.

I doubt Hell's Kitchen had that in stock.
