Not at all. There is many ways to rationalize time, nothing is settled at all. The “settled theory” you talk about would create paradoxes, if time travel is ever made real. And paradoxes don’t work well with reality.

There is actually a fairly common way to rationalize time that is the opposite of what you’re describing: Time is entirely a construct, there is no past, no future, only the present. Take away all of humanity’s memories and the past doesn’t exist at all.

There’s also an understanding of time that says it only goes forward, making time travelling to the past impossible.

It’s not like we actually know how time travel would work. Because, you know, it’s not currently a thing at all.

It still shouldn’t be banned, it should be up for debate when picking a system. Explicitly banning a system is pretty much anti-democratic by nature.

Nothing screams “democracy” like explicitely banning a voting system

Now that is some high quality projection hahaha

If something should work, but it doesn’t, nuke all the caches before diving in the rabbit hole of debugging weird issues
