Shall We Colonize Mars or Planets in other Star Systems?


Colonizing Mars may sound like a good idea, but it would be a nightmare. Very little atmosphere, no protection from radiation, no natural food, no infrastructure, too little gravity, too cold, no grass, no plants, no lakes, no animal, no skinny-dipping, and almost no way to deal with big problems that will absolutely happen. And you’d have to live underground.

Our bodies are adapted to the Earth’s environment in thousands of ways. Colonizing Mars or anywhere else in our solar system would be disastrous.

What about the concern that some disaster could happen to the Earth that would destroy humanity?

I think that within 100 years or so, we’ll have the technology to avoid large asteroid collisions, devastating diseases, super-volcanoes, etc. So after a century or so, I think it’s highly unlikely that any disaster would destroy humanity. (Astrophysicists think the Sun will serve us well for at least a billion years).

World population is expected to top out at less than 10 billion people, and with proper recycling, there are plenty of resources for all. After all, our natural resources do not get used up. (The exceptions are the fossil fuels, but we won’t need them after this century). There is the same amount of iron, aluminum, chromium, and all the other elements, that there were millennia ago.

As far as extra-solar planets, keep dreaming. The planet, Proxima Centauri, is in the nearest star system to our own solar system. And it’s over 4 light years away. At the current speeds of our spacecraft, it would take tens of thousands of years to get there. It would be a miracle if, next century, we could get there in a thousand years.

It would be more of a miracle if we could get there with anyone alive.


What about small, robotic spacecraft? By next century, it's possible but not likely, that we’ll probably be able to send out a bunch of these to various star systems. Once one gets to a planet that it can land on, it could send a transmission back to Earth about what it has found. It can then duplicate itself, and send out more small spaceships. I’ve seen some estimates that we could have these essentially visit every part of our galaxy in 100,000 to 1,000,000 years. A million years seems like a long time, but hominids were around a million years ago. And the dinosaurs died off over 60 million years ago. So it really isn’t as long as it sounds. And we’d know for sure which planets, if any, have intelligent life.

But human colonization of extra-solar planets? We’d need a spaceship to house hundreds of mostly young couples, that can support them for many generations. If you think that’s going to work, you’ve been watching way too many Star Trek and Star Wars’ movies. I know I have.

 
Our only hope is that Elon Musk develops a huge Tesla spacecraft that can travel at ‘ludicrous speed’. Hopefully, we wouldn’t run into a bunch of Klingons.

Excellent.
I always enjoy your blogs.
Makes a lot of sense

Wee√®eeeeeell… At least we’ll be *skinnier* on the scale ;)

This was a very well written article, fun to read and easy to understand.

I'm glad that you pointed out in your blog that, practically speaking, nobody is going to migrate to other planets! Even discussing it seems like such a waste of time to me, since we've been told that it is forbidden that beings from one planet interfere with the life of another planet. Persons of your generation and afterward seem to like to discuss such idiotic (to my generation) topics.

Is it possible to program benevolence into an AI?

Benevolence is really an emotion, just as are anger, enjoyment, and other emotions. 
We have no idea as to how to program a computer (or AI which is a computer program possibly controlling some hardware) to have feelings. We have no idea as to how to program a computer to be self-aware or to care about anything.
There is a debate about this. Some computer scientists think that we’ll eventually be able to program AI’s to have feelings and be self-aware and some computer scientists don’t think so.
And if they do become self-aware, would that be bad? More than a few scientists think so.
Stephen Hawking, for example, has stated: “I think the development of full artificial intelligence could spell the end of the human race.”
Bill Gates, the founder of Microsoft, is equally concerned: "I am in the camp that is concerned about super intelligence. First, the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few deca…

Save us from Leftists

By definition, Leftists want the government to control much of their money and lives. Governments are run by politicians, which have a favorability rating around 15–20%. Who wants them to control the economy or our lives?

If you do, look around at the numerous countries that have tried this. They invariably get corrupt and their people become poor.

I’m not against programs that give money to parents to educate their children as they see fit. I’m also not against programs that give money to each of us to provide for medical expenses. But this money should go to all equally so that we have ‘equal rights before the law’.

If structured properly, these programs don’t allow Congress to control our lives because parents would be able to choose the school for their children.

And adults could choose their doctors and hospitals for them and their children.

Leftists such as United States Senator Elizabeth Warren, “Unveiled a proposal (in February 2019) outlining the Universal Child Care and Earl…

Will mankind survive overpopulation, resource shortage and climate change?

I’m going to reduce the anxiety in your life. Here’s how: Overpopulation is not a problemWe’re not running out of resources“Climate Change” may be disruptive, and it may even be better for humanity Let’s take these one at a time. Overpopulation In 2017 world population is about 7.5 billion. Here is a UN graph of the projected population until 2100:

So it seems Earth’s population will top out this century between 9 to 10 billion people. Modern countries can easily feed, provide clothing and housing, etc., to its citizens. Developing countries have a problem because their governments are corrupt and don’t allow its citizens freedom, especially free markets. As countries modernize they get richer. Notice the growth of China, for instance, because its government has been allowing free enterprise. Natural Resources Reports of running out of natural resources have appeared for decades and maybe a century ago. Instead we’re finding more and more natural resources. Fracking has allowe…
