So, the biggest question I have about all this eminently theoretical physics video thing is, has anyone ever managed to experimentally demonstrate you can __voluntarily__ bend the brane our reality resides on by any measurable amount, and also demonstrate this causes an actual translation in 3d space? At all? Ever?

Or are we conjecturing what would happen if this was even slightly viable?

We've only very recently managed to experimentally demonstrate that unimaginably huge cataclismic events can make this happen, but, has anyone ever built some device that can make a crease of any significance at all in reality, and do so at will?

Bends in spacetime creating measurable effects is how LIGO’s interferometers see gravity waves.

You’re asking for a light bulb when we’ve barely begun grinding lenses for a telescope.

Apologies in advance if this sounds excessively rude, but I'm not asking for anything as there's noone to actually ask to, I'm asking about that.

That distinction matters, since I personally find it easier to derive enthusiasm from concrete, tangible tools that may prevent the entire species as a thing from dying choked in a toxic miasma of our own creation than from the purely numeric advances in our grasp of the rules of a universe we're basically guests in.
