Yes there could be any reason why we don't see aliens or them contacting us. Hell there could be even a combination of reasons. What the point of these Fermi and paradox solutions is to give a possible solution. Not a definite proof of fact, as we have no evidence truly proving any theory or ruling them out.
And yes these are some pet theories I did come up with. That didn't fit the mold of the current laundry list of Fermi and paradox solutions. I listed them because I think that the current list of Fermi and paradox solutions, are filled with confirmation bias. Let's look at the zoo hypothesis one of the favorite Fermi and paradox solutions. It speculates that aliens don't contact us to preserve our "culture". That's how we want aliens to act toward us. We think our culture is so advanced, and /or so special, that any "wise" extraterrestrial race would never change our course of development. For every case of us not interacting with an uncontacted tribe I can find 100 more of when we did interfere with uncontracted people. But this theory still persists. So yes I'm going to list more reasonable theories
Not a lot of them wish to talk about aliens in the first place. Many fear that their careers would be over, if they acknowledge the existence of extraterrestrials. As their colleagues would lump them in with ufologists.
I don't know how you can criticize me for my "lack of evidence", when you do the same. We also had a theory of how Cold Fusion would work, how did that work out for us. It must be that we're not advanced enough civilization to figure out how Cold Fusion works. It not just bad science. It's no our lack of knowledge in the field. The same argument is made here with terraforming.
Just because we have a theory of how something works doesn't mean that's actually how it does work.
And were are we now all these years later. Have we been able to make a successful self-contained ecosystem? It's 50 years later we should've been able to discover by now. How do you think it will take 100, 200, 1000 years to figure that part out. Then how long will it take for us to figure out how to terraform planets, without failing. Or together the resources to terraform planets.
You know in in 1680, we discovered gravity. And now in 2020 we still haven't figured out how to make antigravity machines. I really doubt in 1 billion years that we would ever find a way to make it antigravity machine even with all that time because devise the laws of physics. Just like I believe that an eight 8 billion years we still will not figure out how to time travel. Just because your civilization has billions of years to work on a project doesn't mean he can defy the laws of physics. Now we don't know all the law including all the laws of biology. Yes were discovering new things each day. And sometimes they do invalidate all discoveries. But some laws can't be violated.
Do you have a link to this paper. Any counterpoint to yours I did not say technology was static.
We do not know how long ago our interstellar neighbors came into being. For all we know they are only 500,000 years older than us. They may not have had enough time to get up to the advanced level that you're talking about. Also I don't think exploding thermonuclear bombs behind the spacecraft is an effective solution. It sounds like those people who want to use nuclear weapons to stop hurricanes. Yes I do believe though in nuclear engines but not exploding nukes.
In addition we have no evidence that anyone can reach K2. We base this off the Dyson sphere concept. But this is just our love affair with solar panels. If we had more of a love affair with wind turbines, would be talking about Dyson sails. Dyson Spheaes remind me of the website once came across, called tales of future path. In which people in the 19th century believed that we could build skyscrapers so large that we could land aircraft on them.
This is the same questions I have asked ufologist. What experiment can we produce they could prove that aliens exist.
From what you just told me there's already irrefutable proof that aliens exist. So why do we not to be said that they do exist? Effect wire astrobiologys and astronomers, not pointing out that this evidence proves the existence of intelligent extra terrestrial life?
That was another theory that was about to propose. That our search is the equivalent of each sensor being a bucket thrown into the ocean, searching for a plastic bottle. Even if we have hundreds of thousands of sensors, and some large ones at that may take some time for us to actually collect any artificial object or signal.
