Danger is something that is not easy to define. As you rightly posted wondering where it will come from or where it is are the questions to start from to anticipate and avoid it. So mental preparation whatever the ship, spaceship or airplane we move on is essential. Do we observe something that gives us anxiety or can become dangerous? Rationality and observation; detachment and distancing from the source of potential danger. Understanding and overcoming a danger takes time in a hostile environment and when we move on the three axes, everything can become hostile; man was born to move on the two axes that can be drawn on the ground.

Too unsafe, it could create an unforeseen man made meteor impact, it would be too stupid to create something like that, what we need is a pre impact shield. Something like a massive wall of steel that is compact enough to deflect incoming meteors by a certain angle. These shields should be able to couple and decouple/have their own propulsion systems and be able to connect and disconnect in the event of failure and should be able to organise them selves into a wall of varied thickness, imagine ping pong. To collect degrees, we should have a device that can have varied magnetism and cause incoming debris to rotate around the magnet or deflect (based on the incoming speed of the object) and be able to slow the object while maintaining full control over where they will drop (into the ocean) which means we may need more than one to collect fast incoming magnetic materials.

Men have written a lot; not all men have written by passing on their wisdom and respect for the world by their stories ( oral tradition). I can assure you that in Aboriginal and Native American cultures there are so many concepts that should be brought to the attention of the younger generation. Many of those concepts match up with what you expose. Probably, given the planetary problems we got into, they had good reason to live by those rules . Rediscovering essential values is not looking back, but is changing course to get out of the social crisis that in a thousand ways affects today's civilization in the world. Greeting

It's a theory. In fact, when the sun begins to increase the volume it occupies in space it will create such a decompensation in the orbits of the planets that life on Earth will probably end in a short time ( if technological man has not already completed its destruction autonomously ). In any case, for the cataclysmic version of the end of the world, we will still have to wait at least 4.5 billion years ; for the version in human self-production even a single century could be enough . We need to change the mentality of many earthlings if we want to keep waiting for the big flash of The Sun . Greeting.

I believe that meteors may have helped create life on Earth, either because of the physical effects of the impacts, or because of the chemical components they carried. As we know Organic Life is mainly based on carbon, hydrogen, oxygen and nitrogen in addition to small amounts of other elements. Residues of DNA chains from space are probable, but not very credible as a trigger of life if anything they can prove to us that from the unknown place from which they came life existed. I believe that life on Earth was formed in the primordial chaos that has reigned since the planet assumed the necessary form and orbit stability. in my opinion, however, some pieces are still missing to define with certainty the series of mechanisms that gave rise to the first cells and therefore to the first terrestrial DNA chains. It is clear, however, that today after the completion of the human DNA mapping we know that between a human being and a monkey there is a minimal genetic difference, under 3 %, as well as with pigs ( at other points in the DNA chains ). I do not believe that humanity is ready to "play" with DNA yet; the time of the super race has passed for too little time, and the traumas and devastation it has left are still alive. Perhaps in a few generations, having overcome some serious evils of terrestrial societies, it will be possible to serenely take the human genetic heritage in hand and give it harmony and health in a world free from pollution, hunger and rebalanced in the relationship between man and environment. The road is as long as a journey among the stars. I quote an ancient Chinese sage "even a journey of a thousand miles begins with a step" and we men of today can take that first step. Greeting

The points of view are formed with life experience, mature by experiencing pleasant and unpleasant episodes, going to discover distant places and the people who live there, meditate and understand the differences and difficulties of others. Then if we realize that our knowledge and our having learned do not make us understand what we are experiencing at that moment... then... it is time to travel again to our places and among our people to rediscover them and listen to what they say and understand what has changed.
