I tried Minetest a while ago and was never really able to get into it. The new player experience was rough, a lot of decision paralysis. The texture style can vary between mods and servers. It didn’t feel very cohesive. I don’t know if that has changed since I last played, but to me it didn’t feel like a minecraft killer then.

From what I can tell, Hytale was supposed to be a bit like Terreria in 3D, as well as a platform for minigames. The gameplay and graphics from the trailers looked really good. I’m sure it would have been a Minecraft killer for some. (Ex. players who primarily play for the minigames like bedwars)

Sourcing the carbon from the atmosphere is still better than getting it from the ground. It turns a net positive emission source into net zero.

It may be worth it to decide how we define ‘unstoppable force’ and ‘immovable object’.

An Immovable Object has 0 velocity:

v = 0

Acceleration is the time derivative of velocity:

a = d/dt(v(t))

a = d/dt(0)

a = 0

And we know that

a = F_net / m

An object with infinite mass would satisfy this equation, but an object with no net force would too. We could add a correction force that will satisfy the constraint of 0 net force.

|F_net| = 0

∑F_i = 0

F_correction + … = 0

To satisfy Newton’s 3rd law, we would need a reaction force to our correction force somewhere, but let’s not worry about that for now.

A physics definition of ‘Unstoppable Force’ is:

|F_unstoppable| =/= 0

In this case the gravitational force fits this description, given a few constraints

F_g = Gm∑ M_i / x_i²

As long as the gravitational constant G is not 0, our object has mass, and

∑ M_i / x_i² =/= 0, then

|F_g| > 0

But this does feel kinda like cheating because it’s not really what people mean by ‘unstoppable force’. the other way to define it is just immovable object in a different reference frame.

a = 0, |v| > 0

I’m gonna stop here because this is annoying to type out on mobile
