If someone was taken into a 4th spatial dimension, what would it look and feel like? How would our brains interpret it?

This is ignorant nonsense.

Unlike the garbage you're spewing?

It's certainly not useless and it's certainly not a requirement to actually live in a space of said number of dimensions to verify the accuracy.

Okay, tell me exactly what I would be seeing if everything had an extra dimension, including the illusion of time. Tell me what my ape brain would be seeing and how it would react to what I'm seeing.

I'm not talking about slices of a simulation, I'm talking about the real thing.

Also wrong. That's 4.

Where's the temporal dimension in all of this?

The temporal dimensions is not entropy.

What else could it be?

There's more of a suspicion that the second law of thermodynamics is connected to the arrow of time but it's not settled and the second law isn't the same as entropy.

What are you even talking about.

There's no basis for this and the previous statement that energy is transferred in linear fashion

What the hell are you even talking about.

The only thing that could be said is that a universe with multiple time dimensions would lose predictability by physics

Wow, you admitted to it, you don't have a clue what would actually happen and what we would see. First step: acceptance, congratulations.

but 4 spacial dimensions doesn't mean multiple time dimensions as you wrongly assert earlier

We're talking about a world that is purely 4-D. Try again.

This is so trivial that we have absolutely no issue understanding a 4d (or any d) cube.

Okay, tell me what my brain would be seeing and how it would react to seeing an object. It's terrific that we have "no issue understanding" it, it's a different matter entirely actually seeing it.

Try again.

Much of your life depends on a deep understanding of mathematics these days.

No shit.

If we couldn't understand something as trivial as 4d space we wouldn't be able to build any of the technology you are using to type this post.

We're not talking about understanding it, we're talking about actually seeing an entire universe comprised of 4-D.

Are you even trying here? Do you even know what we're talking about here? Are you lost?

Jesus, try again.
