Some thoughts about universes

I'm recently very much into universe multiverse, theories, also quantum physics.  I listen to the astrophysicist Neil Tyson de Grasse and I love listening to him. And some time ago I heard a theory, that maybe our universe is inside of a black hole. According to Einstein theory black holes host their own space time, they preserve matter, electric charge and angular momentum, which would allow galaxies to develop. And here it could also answer the Fermi paradox: where is everyone? Maybe we don't hear anyone, because maybe we are alone in our universe (black hole) there might be also different explanations, like aliens using telepathy instead of radio waves for communication.  I drew some series of pictures related to this topic. I'm curious, if there is anyone Aldo interested with this topic and what are other people's thoughts. 

Here it says "haha these funny little humans use radio waves for communication and expect the same from us."

  • The issue I have is most depictions of aliens are like us only with green skin and elongated skulls making them somewhat comparable to humans at first glance and they tend to have two arms and two legs too. All these human features have taken millions of years to evolve on earth under earths natural rules of evolution. It assumes a lot to begin to think aliens would be anything like us. Life as we know it requires certain elements to grow and much of space is extremely lacking in these life giving properties. I wouldn’t discount aliens altogether though because if we go down the route of different universes then the aliens big bang may have contained unknown elements not known to this universe. 

  • This is an interesting thought actually. Considering how many species there are on our own planet (of which we were definitely not the first) it is statistically unlikely that if alien life did exist then it would be anything like us. Particularly because other planets have a completely different atmosphere etc which would mean if there was a possibility of a life surviving there, the survival mechanisms would be very, very different to ours. I'm not sure whether I believe there are aliens out there - I certainly do not think there are little green people running around. But I do find it baffling that one planet could have so much life on it and so many others seemingly none. But there are many galaxies other than ours and so much of space unexplored, I don't think it could ever be ruled out.

  • If aliens are real do they watch us or study us in some way and if so why do they do that? Is it a Star Trek type mission to catalogue the universe and its inhabitants or do they know what we are capable of and avoid us due to our destructive tendencies. We can’t assume they’d invade because what would be their motivation for such an act?. If we imagine ourselves coming across another form of life in the vast expanse of space what would humans choose to do I wonder? I think they’d study it out of interest and curiosity. 

  • It does seem to be making a comeback recently, the alien theme has been in the news the last few days with this from the BBC

    It’s either a ploy by the powers that be to seem more transparent or they are exposing us to UFOs and UFO sightings because they’ve become more frequent lately. This sighting is an orb tracked off the coast of Yemen taking a direct hit from a missile and proceeding to carry on as if it was nothing.
