I understand dark energy permeates all space in the universe homogeneously. And it powers the expansion of space. Imagine a warp drive which sucks up the dark energy of space in front of it thus collapsing that space to propel the ship forward, leaving a trail of "no space" behind it. This allows faster than light travel because there will be nowhere the ship existed between its starting point and its destination. All the space where it had been during the trip will be gone.

At the moment dark energy is more like a theoretical / mathematical concept. A placeholder for something we do not understand if you will. Building a means of transportation based on that will be challenging but good luck with it...

I think this has been already proposed as one way to ''travel faster'' than the SOL; just try ''space warp propulsion'' on Google.

Thanks.

It can still turn out that it's really about space/time geometry or something, and there is no dark energy or matter at all, right?

Based on my understanding of current and past cosmology, absolutely. It could even all just be something like observational biases, incorrect assumptions, measurement errors or any combination of these. Measuring things that are far far away is inherently difficult, and we have no way of travelling to places that maybe would be good study grounds for certain assumptions. The only thing that we have is light, which is useful but only one way of studying things. Many things science have been observed and confirmed by several independent methods, but in cosmology you cannot do that too much, you have to rely mainly on stuff that has no (or if it has, extremely little) mass, has travelled a long way in space and time and has some other properties that make it not an ideal messenger.
Before covid I was on an outreach trip from HK to some other countries with a group that included a theoretical physicist. Based on what he said, even for stuff that is measured at the LHC and similar colliders, there is a lot more uncertainty than what is commonly known/anticipated. But ofc this kind of stuff does usually not sell well in grant applications and stuff so you don't hear about it too much.

If its possible to go faster than the SOL then aliens would already be here if they were advanced and existed.
If they are advanced and exist, how do we see them?
We need special glasses ofc.
Its called sleep deprivation
****ING TEST IT BRO
Start making fun of aliens and then check your ass for probes.

Milk. Out. Nose. <3
And buzz was an alien in that movie?!?!?!
Holy ****ing **** this is getting deep bro.
