Exoplanets and Fermi paradox: can we ever get an answer from other civilizations?

Stargate.  The idea of Stargate is that there should be a ring-shaped light wave on the frame. The system puts that light wave ring rotate very fast. Then there is a similar frame at the receiving side. The energy level of the receiving light ring should be lower.  The energy level must be higher on the transmitting side. The system puts those light rings in superposition and entanglement. And that should make the quantum tornado between those two frames.  Information travels between those superpositioned and entangled photon rings. The thing. What this system requires. Is energy. The system needs lots of energy to transport objects between planets and stars. So theoretically that system requires a black hole to focus enough energy into the frame that it can create a quantum tornado or wormhole.  That is tight enough. That means the interplanetary system that transports people is far away in the future. But that system can make long-distance quantum teleportation tru...

SETI, AI, and mirror bacteria.  Can the first alien encounter happen with a creature that we created ourselves?  If we want to find "another Earth".   First, we must determine. What does that other Earth mean this time? The other earth doesn't mean that there are any lifeforms. Or lifeforms are possible in the way we know them.   Does that mean a rocky planet? That is frozen like some giant Pluto? Or does that mean some locked planet? Or a planet where aliens listen to jazz music?  There is one interesting idea about the hypothetical alien civilizations. That could be at our level. They might reach Kardachev-scale 1. And that means they are only a little ahead of us. It's possible. We think that the messages that those civilizations send are coming from our own military forces. In that case, we must realize that the aliens might not want to send messages to other civilizations.  In that case, the data that the hypothetical civilization sends is acciden...
