Just imagine if we could develop a kind of space craft to send humans there, They meet up and we infect them with the COVID virus, I wonder what they would think of us ?????

About as much as what the rest of the world thinks of China! :sick:

"They are 'super-Earth' planets, which means that they are a few times the mass of the Earth and are expected to have a solid core like the Earth, as opposed to the big gas giants such as Jupiter and Saturn,"

Not entirely correct. Both Jupiter and Saturn are suspected of having rocky cores. They would have formed mostly from the same stuff (granted with more ice), then simply hoovered up massive atmospheres.

Only 100 trillion kms. Unless there is some major breakthrough in faster than light travel !! we will never see them.

Common misconception that one would need to attain light, or faster than light, speed - e.g, typical thinking: if these exoplanets are 11 LY away > travel at light speed and get there in 11 years. As an outside observer, yes, but as per Einstein's equations and time dilation, one 'merely' needs to approach light speed to cross vast distances faster (for the traveller).

Ponder this: Light itself will cross the entire universe somewhere between instantaneously and a couple seconds.

And yet, scientists tell us they're looking at cosmic events that happened 13 billion years ago, because that's how long it took the light to arrive...

Hopefully it will take that long for these guys to get here

I think there will be 3 levels of aliens out there in the universe/space.

1. Those that evolved up to Dinosaurs and no further.

2. Those whose planetary events led to another species - like humans - evolving into a higher species and they will be similar to us in advancement.

3. Those aliens that evolved prior to the big bang, had the capability to survive it and would never see us as more than an ant colony

From our perspective the light does indeed take that long to reach us. But according to Special Relativity time stops at the speed of light, so photons feel no time and also feel no distance, so for the photon the time from emission to absorption is instantaneous.

and what if they infect us with some fancy intergalactic virus 1000 times more potent than C-19 ?  I have no interest to shake hands with any small green men 🙂

We don't need to think about what would occur, we only need to look at human history.

 

When the first Europeans "discovered(?!)" North/Central/South America, they brought small pox which eviscerated the local populations who had no resistance to it. Hmm... Did the same occur in Australia with the Aborigines (any Aussies want to comment; I don't know)? I think the questions would be which civilization infected the other worse and which was able to withstand it. Hmm... and whether it would be seen as an accident or as biological warfare.

 

Thanks to members for the comments on the Drake Equation; it is good to hear that it is being expanded(?) to cover non-Terran environments as well as the thoughts that we are actually inputting numbers into it. Yes, it is going to follow the GIGO Principle (Garbage In/Garbage Out), but I like the idea that there is some kind of intellectual structure evolving to categorize thinking regarding alien life.

 

One final thought, which might make me sounds like a whack-job...

 

What if alien life is already on earth and we simply do not recognize it? Would we recognize a species that is green and plant-like, but which communicates via odorless chemicals and reproduces by subterranean, microscopic spores? Would we even see/notice a species that is gaseous (hmm... would either of us recognize the other?)? What if there is alien life which exists only as energy and/or consciousness? Again, would either of us notice the other?

 

We live in a fascinating era of discovery about the universe/space; I truly hope that the discoveries keep coming and our knowledge keeps increasing.

 

Go curiosity! Go exploration!

Intelligent life if it is around would want to avoid us. We are pretty violent as a species and look what we did with our planet.

Exactly. If there is intelligent life there they'll be shooting down the space ships before they can get back to earth and bring the hordes from our overpopulated, polluted and dying planet.

Because they would be better off than us? Their planet would be a green paradise and they'll live in harmony with it?

I hear TAT has already sent Love Aliens signs to them and announced no visa needed.

Don't we have enough "extraterrestrial" living here on Earth already? If there are any out there umpteen light years away, I hope they stay out there.

And if extra terrestrials DO land on Planet Earth...............I'm sure that DRJack will be on hand telling them to "Go back home " 🙂
