proszę o naj!:(((
1. I think it's possible, cause people are still learning about mars and they are sending satelites. In my opinion people are curious about life on the other planets, so if technology will get better it can happen, but not in next years
2 I don't think that can happen in 20 years. Maybe in next centuries? It's even really hard to imagine to teleporting cause it sounds like science fiction film.
3. I'm sure about that, cause universe is really big and we still haven't found out about it. We only know a few planets and we can't be alone.
4. It will be kinda scarry but also interesting. If they will be nice and they wouldn't destroy our planet it will be really nice experience. I also think that friends with them would bring us some benefits and new oppurtunities
