It's actually entirely possible that there is no other life in the universe but us. If we exist, aliens should be able to exist too. Even so it's also possible that a race of aliens so technologically advanced managed to actually leave this universe to create their own. This would require either another realm or dimension. Since we live in only 3 dimensions I doubt creating or be able to use a "4th dimension" is possible. I honestly dont even think there is. The concept of "realms" seem stupid tho.
Our universe will inevitably die. They are probably off making a universe that won't die.
It will die, it a loving long period of time. Like a few centillion years maybe.
I laugh at people who think that the only possibility of other life in the galaxy is super-intelligent beings with tech way beyond us.
A part of me wants to believe that we are the hyper-advanced species that's going to go forget up some other planet long into our future.
People thinking intelligent life automaticly means super hgh tech are stupid.
The reason we havent got a "reply" from our radio signals send into space are either because
- "they" dont have the technology to detect them
- "they" can detect them but have no idea what the hell it is
- "they" they know its "us" but have no means or way of "replying"
- "they" found us but leave us be
