Awhile back, I wrote a post related to living on Mars. Today I came across an article promoting a book entitled,
“The Next 500 Years: Engineering Humanity for Life After Earth.”
I have no plans to purchase the book, but I did read the article … and thought some of my blog visitors might find it interesting.
Here’s the lead-in:
HUMANITY’s long-term prospects are weak, at best. If we don’t all kill each other with nuclear weapons, a planet-killing asteroid can’t be too far off. And anyway, the sun itself will (eventually) expand, obliterating all traces of life in our system. Let’s not even get started on pandemics.
As if awareness of our own mortality hasn’t given us enough to fret about, we are also capable of imagining our own species’ extinction. Once we do that, though, are we not ethically bound to do something about it?
Apparently this fellow thinks in the far distant future we will have the ways and means to carve out our place somewhere in the universe.
One thing’s for sure — his outlook for such a venture is most definitely ambitious!

No doubt many of you have read about the recent and “much-awaited” preliminary report on the government’s assessment of UFO phenomena.
According to this article, “The report finds that an overwhelming majority of more than 120 sightings in the past 20 years did not come from any U.S. military or other government technology.”
So the next question automatically becomes: Where did they come from?
Some have promoted the theory that they are super-advanced foreign military craft. Others have commented that the phenomena may be “alien” spacecraft — not necessarily “extraterrestrial” but rather “experimental technology” developed by other countries.
Both of these scenarios are naturally a chief concern for the United States because if hostile countries are involved, that would threaten the world’s largest military power.
Of course there are untold numbers who insist the objects are most certainly and definitely “otherworldly.”
From my personal perspective, I tend to agree with Michael Shermer, editor of Skeptic magazine. Michael is a science historian and a longtime analyst of UFO theories and other phenomena – and he points out the blurry and hazy element to the sightings. He notes that several billion people have smartphones that take crisp, clear images, not to mention satellites that can precisely render detail on the ground.
He then puts forth this challenge: “Show me the body, show me the spacecraft, or show me the really high quality videos and photographs … and I’ll believe.”
I admit that when I was considerably younger, I fancied the idea of visitors from other parts of the universe. Looking back, I’m sure it had a lot to do with my love of sci-fi movies. In fact, one of my favorites was “The Day the Earth Stood Still” (the 1951 version), in which an alien lands and tells the people of Earth that they must live peacefully or be destroyed as a danger to other planets. (Actually, the warning in the movie is not so far-fetched even today.)
However, as I matured, I began to see things differently. Based on my current perspective, there are simply too many rational thinking hurdles to overcome for me to accept the idea of extraterrestrial visitors.
Yet … stranger things have happened.
What’s your take? Will these blurry images that move and shift and disappear in the blink of an eye be explained in the final governmental report? Or will they remain in the UFO file with a “to-be-determined-later” notation?
P.S. Further reading on this topic can be found here.
The recent news related to the planet Mars, the Perseverance rover, and the Ingenuity helicopter has caused me to ponder the prospect of Living on Mars. No, I’m not referring to potential future exploratory “visits” by space-age scientists. I’m talking about taking up residence full-time. And I’m going to say this upfront —
I don’t think it will ever happen.
While I’m fully aware that science continues to present us humans with unimaginable advancements –and things aren’t slowing down (especially in the areas of space exploration)– I simply cannot visualize humans taking up full-time residence on Mars.
Let’s think about this for a minute.
The only way humans could actually live on the Red Planet would be in some sort of climate/air-controlled facility. They could never step foot outside without appropriate protection and breathing apparatus.
Further, when one considers the geography of Mars as presented via various advanced imaging apparatus, the surface appears to be relatively barren. Lots of rocks. Some craters. Overall, a mostly desert-like surface.
In other words … No forests. No rivers. No oceans. No grass. No birds. No animals. No reptiles. No fish. None of the beautiful and intriguing things that Earth offers in plenitude. Of course this also means no swimming, no bird-watching, no fishing, etc.
Add to this the frequent dust storms, the C.O.L.D. climate (average temp -81 degrees Fahrenheit; -62.77778 Celsius), and the thin air. (Those white fluffy clouds that often accent Earth’s blue skies? Non-existent on Mars.)
These are just some of the things that make me think full-time life on Mars by the average earth-abiding citizen will never come to pass. This isn’t to say that scientists may one day determine how to travel to, live on, and study the Red Planet. But for people like you and me to make our home on such barrenness seems extremely far-fetched. And for most of us, I would think very unappealing.
However, this isn’t to say the future could include sightseeing visits to the planet in an environmentally-controlled space craft that will circle the planet and allow earth people to view its mysteries. After all, we do have people living in a Space Station, so surely, a “taxi-ride” to the Red Planet is futuristically conceivable.
The article references a certain theoretical physicist named Miguel Alcubierre who contends that “motion faster than the speed of light … is possible.”
However, some seem to feel this is an unlikely event because:
[A}n Alcubierre drive would expend a tremendous amount of energy—likely more than what’s available within the universe—to contract and twist space-time in front of it and create a bubble.
And some scientists have criticized the Alcubierre drive because …
it requires too much mass and negative energy for humans to ever seriously construct a warp-based propulsion system.
However, there is a new study in which some scientists offer the following:
Where the existing paradigm uses negative energy—exotic matter that doesn’t exist and can’t be generated within our current understanding of the universe—this new concept uses floating bubbles of spacetime rather than floating ships in spacetime.
The article closes thus:
[W]hile a physical drive may not be a reality today, tomorrow, or even a century from now—let’s hope it’s not that long—with this exciting new model, warp speed travel is now a lot more likely in a much shorter timespan than we previously thought.
If all this seems like Greek to you, you’re not alone. But I think there’s enough in the article to challenge those who believe our future is “in the stars.”
Do you agree with the following statement? It was included in an email that I regularly receive from New Scientist ..
The search for extraterrestrial life is one of the most exciting frontiers in astronomy.
The astrophysicist who made the statement also mused that … We might turn out to be a form of life as primitive and common in the cosmos as ants are in a kitchen.
Just out of curiosity … what are your thoughts? Do you think extraterrestrial life will be discovered in your lifetime? And if so, will it be as described by the astrophysicist — or do you speculate that it will be far advanced? How do you think such a discovery would jive with the religiously-oriented?
I used to think it was awful that life was so unfair. Then I thought, 'wouldn't it be much worse if life *were* fair, and all the terrible things that happen to us come because we actually deserve them?' So now I take great comfort in the general hostility and unfairness of the universe. - M. Cole
