Fascinating account of a very far away event long, long ago

Like 50,000,000 years ago scientists believe this unfounded black hole may have started forming. These ā€œspace scientistsā€ invest their life studying the universe and the formation of galaxies. To them, the science is in the stars, how they are formed and what propels them, what shapes them, etc.

I have been looking at stars for years. Whenever the discussion comes up about the universe, stars, moon, etc., it turns into a boring conversation for most people. I toured NASA in Florida several times and each time I learn something new. I have also been to the observation point to see a launch, which was a ā€œblast.ā€
 
was reading something about space in the news lately and what lies beyond our universe, probably other universes or ??? the item went into detail about the shape of our universe but my question has always been no matter what the shape is if it ends someplace and is contained what contains it? does it just stop, like the end of a rope? then it is hard to imagine there being other things beyond..

In the magazine I read, there was an article about the universe and how many galaxies there are. Astronomers and Space Scientists agree that there are probably as many as 200 billion galaxies. Can you imagine how many stars that would be, plus remnants of old stars, gases and dust? The universe actually has an indefinite size due to it expanding yearly. I donā€™t think you or I have the knowledge to give a close approximation of the measurement today.

I keep wondering how far into space or the universe we can go and why would it be necessary to keep going deeper. I also think about if we go deeper into the universe, we have to be able to return. I donā€™t think even NASA or Elon Musk is ready for that.

Think of the universe like a balloon partially blown up, and still getting bigger--but with one alteration. All of the universe is only the surface of the balloon. That is what Relativity means by the curvature of space. There is no container, no outside and no edge.
 
Enrico Fermi, a Nobel prizewinner who built the first nuclear reactor, never published a word on the subject of extraterrestrials. We know something about his views because physicist Eric Jones collected written accounts from the three surviving people present at a 1950 lunch in Los Alamos where the so-called Fermi paradox had its roots: Emil Konopinski, Edward Teller, and Herbert York (Fermi died in 1954).


According to these eyewitnesses, they were chatting about a cartoon in The New Yorker showing cheerful aliens emerging from a flying saucer carrying trash cans stolen from the streets of New York City, and Fermi asked ā€œWhere is everybody?ā€ Everyone realized he was referring to the fact that we havenā€™t seen any alien spaceships, and the conversation turned to the feasibility of interstellar travel. York seemed to have had the clearest memory, recalling of Fermi:


ā€œ... he went on to conclude that the reason that we hadnā€™t been visited might be that interstellar flight is impossible, or, if it is possible, always judged to be not worth the effort, or technological civilization doesnā€™t last long enough for it to happen.ā€

quote from scientific american
 
I am and have always been of the mind that WE are the aliens, discended from our ancestors who traveled here for some reason be it exploring or running from aggressors. there is a very good quote in a book where the analogy is made about technology advancement. It can only happen if there are enough people to support it. so if your space ship is damaged in some way and here is where you are you must survive based on what your group of people can provide in the way of food, shelter, manufacturing, and if you cannot keep up the current standard then you must fall back to something that you can sustain. and if you fall back far enough then you return to the hunter gatheror stage and advance forward from that point.....

Agreed! Not a believer of creationism or Darwinism either. I think the first people on the Earth were explorers , adventurers from other worlds assigned to inhabit the new world in several different areas, which over centuries, had to acclimate to different parts of the world.
had to invent earth time (which is distorted). I think the world is zillions of years older that is thought.
 
I think there is a flaw in that argument. If another race of humanoids did land on Earth many years ago, they must have had the technology to do so and were clever, intelligent beings. It would seem likely that rather than lowering themselves to the current population, we would have seen a sharp rise in technical advancement at that time and recorded evidence of the event. Instead we don't even have cave paintings or carvings that can definitely depict extraterrestrials. What advancement we have seen is a succession of steps over many millennia. There is also the assumption that these 'people' would be compatible with whatever species of human was predominant at the time.

I think that Fermi had it right.
 
who said they had to be compatible? yes if they were that advanced could they not clone a new species? but the biggie here is that they did not have enough people with them to sustain their current life style thus they had to fall back to something else. i.e. for you sifi folks, taking the uss enterprise 1701 as an example. the total number of people on board was about 1000 crew and families. the ship could hold many more so much of the time it was empty. this number of people,even with high technology could not sustain their level of society even if they increased their birth rate.
So the ship is damaged to the point it can no longer navigate space and they are stranded in orbit around the earth or maybe mars, beam down of shuttle down to planet side and struggle to survive.
I think that last statement of not being able to survive long enough to be spaceworth is the best answer.

I donā€™t think I meet the legal definition of an alien.
 
There's a good documentary on Netflix called A Trip to Infinity. Very entertaining and really gives you a breathtaking understanding of how tiny we (and our planet) are, and how incredibly immense the universe is. And how strange. There could be an infinite number of universes, with wormholes, black holes, and other phenomena too weird for us to even begin to comprehend.
