I M watching a science documentary about The Telescope and it all makes sense. Humanity must first be able to see what, actually, is in our galactic bubble, surrounding our home world, before we can physically travel  the cosmos. Did you know, when Hubble starred at a patch of sky, the size of a drinking straw, for ten days, it reveiled ‘ The Hubble Deep Field ‘!
I M amazed! Almost every point of light is a galaxy, 100,000 of them in that drinking straw sized patch of sky, and they go on forever! There are galaxies at the edge of our observable universe, 13.7 billion light years, that are moving away from us, faster than the speed of light.
Take our one galaxy, The Milky Way, all the stars, 100 billion of them, and most of them have planets circling them. I think if I were a space faring, intelligent alien race looking for a permanent home, I would choose a solar system with a Red Dwarf Star. The majority of red dwarf stars have rocky, terrestrial planets a little larger,(1.1- 2.5 times the radius), than Earth.  When the radius of the exoplanet approaches 1.8 or more, the majority  retain hydrogen atmospheres, so we are interested in exoplanets with a radius of 1.6 or less. The thing is red dwarf stars are long lived. Earth’s star, our sun, is a yellow dwarf, (G colour) and has a life expectancy of maybe 12-15 billion years. At about 9 billion years, ( 4.5 billion years from now ), our sun will have used up much of it’s hydrogen and swell up in size to around the orbit of Mars. It will be a red giant star. After it’s red giant phase, the outer layers will shed off, and we will be left with a burnt out shell of a star, a few thousand miles in diameter, called a white dwarf. Red dwarf stars consume their hydrogen fuel much more slowly. Their average life expectancy is in the 100’s of billions years and the star remains relatively the same, irregardless of age, except the older the red dwarf, the more calmer it becomes. The habitable zone of a red dwarf is inside the orbit of Mercury. A typical orbit for a habitable superearth would be 30-120 days, depending on the size of the red dwarf sun. They are typically 10-40% the size of our sun, Sol, and have a surface temperature of 3000-4000 degrees C. Our sun, Sol, has a surface temperature of 5500-6000 degrees C.
With the new James Webb Telescope, next generation, we will be able to read the atmosphere’s of planets around other stars.
When we look up at the stars, we are seeing back into the past. We are seeing everything, the galaxies, the stars, the planets, all, as they were, not as they are right now. We are confined to the speed of light when searching our universe. If aliens lived in a star system 2000 light years away, and they looked at our planet with a telescope, they would see us, not as we are now, but as we were, 2000 years ago. We are separated, not just by unimaginably enormous  distances, but by time also. If the exo-solar system is moving towards or away from us, it will also effect the time dilation, so ‘chance’, I believe, will have as much to do with finding extraterrestrial intelligent life, as our technology will.
More likely, if there are superadvanced  extraterrestrials, they would be aware of us and for some reason, not making their presence known. I always remember what happens here on Earth when a more advanced civilization discovers a less advanced one. Complete destruction of the less advanced society. And this is the same species! Imagine an advanced, totally alien species meeting 21st century man. If I were this truly advanced, extraterrestrial civilization, I would do my best to blend in with the natives. Hell, they might have been observing us, for quite some time.
Imagine what they might think of humanity. We are capable of much and sometimes that is not such a good thing. We must learn to share and should realize, there are other intelligent, sentient beings we share this planet with. Until recently, humanity hunted the Cetacean species, almost, so close, to extinction. We should seriously consider a diplomatic mission with the Cetaceans. About 5 years ago, a Bowhead Whale beached himself on some northern Canadian shore. He was quite old and dying. Scientists noticed the metal tip of a spear, imbedded in the side of his face, his ‘cheek’, and it had been there for quite some time. They carbon dated the metal tip and it came back as late 18th century, (1790’s). Wow! That would put the age of this Bowhead at over 200 years of age! Freakin  Wow!
That would mean, any Cetacean over the age of 50, would remember humans hunting them relentlessly, like wolves. Except wolves only take what they need, humans, it seems, always take all that there is. In fact, there are countries, a few, that still  hunt whales. They say it is for scientific purposes, but their own scientists say it is for economic purposes. They are eating them for crying out loud! I will not even get into what humanity is doing to the waterways and rainforests of this planet,  including their inhabitants. Let’s face it. As the dominant intelligent species of this world, we are responsible for more than just ourselves. We must learn to share because the universe is watching and it is, the right thing to do!
