Don’t know how you got the idea of infinite energy. Our universe has zero net energy. Too long of a discussion to go into so we leave it here.

Imagine you are living inside an opaque balloon. You can’t see outside but there are other balloons floating around. If any two balloons get pressed against each other then you can indirectly observe that from inside of your balloon.

Our universe is homogeneous all around in terms of distribution of matter and temp of the edge of the universe. Theory is that if another universe presses against the boundary of our universe then we should be able to observe that as an inconsistency (just like you can see indention of other balloon pressing against your balloon, even from inside). Scientists have found inconsistent regions of our universe where either the temp is below the average or there are no galaxies (great void). There is no direct proof that another universe is pressing against ours, but the point is that we probably can test the existence of another universe under some very specific conditions

Comments in here take me back to the membrane theory. This theory....to me....offers an explanation of how the universe can start from a single point and have inflation... If you have 2 sheets of paper representing the seperate universes and you touch them flat against each other then you get a single point of contact along the entire sheets of paper. That makes the beginning of the universe a single point but the bang occurs along the entire plane, making it appear to be....inflation? Who knows, maybe our universe is over 300 b light years along the plane but only a 15-90 b from top to bottom....

Right now our universe is this planet. At least that’s how I think we need to start viewing this organic spaceship,.and we do have a profound effect on it. Also, while our tiny planet is an insignificant dot in the universe, you have no way of knowing our significance unless you are an all-knowing deity or can see the future. Maybe we seed and populate the rest of the universe once we get our shit together. Or maybe we blow ourselves up with nukes before we get there. Who knows? I don’t, and I don’t think you can say for sure either.

I assume that this is either for a story or you're a supervillain looking to commit a very complicated crime. Either way, I support the idea.

If space travel is cheap and common, then it would be very difficult to stop other travellers from dropping by. Similarly, if Earth wanted to make a concerted effort to communicate with the colony, then Earth could probably communicate. So you've probably got to look at avoiding communication both ways.

First step: launch a vessel that can convert an asteroid to a low emissions stealth base. Obfuscate the launch with something like a false flight plan.

Second step: destroy all radio technology, delete all information relating to radio technology from the records. No radar, no radio, everything is hardwired.
