If there are so many aliens out there, where are they?

With the recent disclosure by the American Army and Navy of unexplained sightings of flying objects, the question of extraterrestrial life comes back to the surface.
The famous Italian physicist Enrico Fermi summed up the question of extraterrestrial life in the summer of 1950 by saying, “But where is everybody?”
He was joking about the fact that we haven’t been contacted by aliens yet, although in theory they exist. This the Fermi Paradox.

The Fermi Paradox

The Fermi Paradox is: The apparent contradiction between the lack of evidence of extraterrestrial civilizations and various high estimates for their probability.
Our galaxy, the Milky Way, has between 100 and 400 billion stars and an estimated 1 trillion planets. There are millions of galaxies in the universe so extraterrestrial life should be a common occurrence.
There are several statements related to the Fermi paradox.
The aliens are listening to us but no one is transmitting anything back.
The aliens fear communicating with us because it’s considered dangerous.
Earth and humans are avoided to allow for its natural evolution and development to happen.
Alien life is already here but we don’t see it.

A series of possible scenarios have been put forth to explain the paradox.
1. Aliens do exist but are not communicating with us.
2. Aliens are communicating but we can’t hear them.
3. Aliens have been here but we weren’t here. (They came before humans were here as a species.)
4. Aliens exist but most people don’t know it yet.
5. Aliens have existed but now have disappeared. (The lifetime of the alien civilization was too short.)
6. We aren’t interesting for the aliens. (Only a few humans are interested by insect societies.)
7. We may already have received signals but didn’t realize it or understand them. (Dr. Frank Drake working with NASA was the founder of SETI, Search for Extraterrestrial Intelligence, in 1960, which uses radiotelescopes to listen for messages from space.)

First Contact

Issues with contacting E.T.
1. Should we try to contact aliens?
2. Who should speak for Earth?
3. What should we say?
In 2010, the English physicist Stephen Hawking said, “Aliens almost certainly exist but humanity should avoid making contact.” He explained that aliens might simply raid the Earth for resources and move on.

Too late! We have already disclosed data about Earth.

In 1972, Pioneer 10, then 11, space probes designed to fly by Jupiter and Saturn were launched. Following the recommendations of the American astronomer and cosmologist Carl Sagan, they contained a gold plated plaque with a physical representation of the date and location of Earth in the universe and a drawing of two human figures. They are still traveling at this time.

In 1974, a mathematical message designed by the American astronomer and astrophysicist Dr. Frank Drake was sent in space to the region of Magellan 31 with the help of the Arecibo radiotelescope in Puerto Rico. (The telescope collapsed in 2020 following the break of its main support cables.)
The Arecibo Message

In 1977, two robotic interstellar probes, Voyager 1 and 2, were launched from Cape Canaveral, in space so that they could take pictures of Jupiter and Saturn, then later of Uranus and Neptune. “Each space probe carries a gold-plated audio-visual disc in the event that either spacecraft is ever found by intelligent life-forms from other planetary systems. The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from the people” in 55 languages, and different “Sounds of Earth”, including music by famous composers and modern music. It also contains photos of Earth and the structure of our DNA!
As of 2021, the two probes are still operational and have reached the interstellar medium but are not beyond the boundaries of our solar System. They are still transmitting data.

In 1999, SETI at home started to use an army of 5 million amateur internet users to process data collected by radiotelescopes across the world.

This concludes an overview of our attempts to communicate with aliens. We have not yet received any consistent signal from outer space but we have only been listening for about 60 years, a mere second in spacetime. However, perhaps we should use caution before we continue to send out information in deep space. Who knows who could be listening!

Why are reviews so important? Tips and Tricks for Authors

Hello my friends. A reminder for all the readers out there.


Why reviews matter to readers and authors.

More than one thousand books are published every week. With so many choices, readers search on the internet for books to read in the genre they like. They read reviews to get a glimpse at the story and how people feel about the characters. Reviews help the reader see how many people have read a book and help them to decide whether to purchase it or not.
It’s the same with movies. People look at the reviews to help them choose which movie or video to watch.
For authors, reviews give them feedback on how the readers feel about their book. The author can then use this to improve his writing. If the reviews are good, especially coming from someone not in the immediate circle of friends and family, reviews validate the author’s writing. Reviews also drive sales. Most avid readers don’t take…

A unique planet. Let’s celebrate Earth. Our beautiful planet.

Why do scientists consider Earth unique even in 2021? Well of course, because it’s the home of so many varieties of life forms and also home to the most complex being we know of to date: humans!

Seriously, there are several important features that make Earth a unique planet.

Let’s go over a few of them.

The Goldilocks zone.
Earth is the third planet from the Sun and, until now, is the only one known to harbor life. Its location in the solar system is strategic because it contains water in liquid form on its surface. Earth is in what is called the Goldilocks zone, meaning not too far from the sun for all the water to freeze solid and not too close that the water would be vaporized.
We believe through radiometric dating that our planet is about 4.5 billion years old.
Earth is the densest and largest solid planet in our solar system. 71% of its surface is covered in water and 29% is covered by land. Scientists tell us that most of the water on Earth came from ice from asteroids and meteors which hit Earth in its early history. Hard to believe, isn’t it?

About 4 billion years ago, a chemical reaction produced complex molecules which mingled together and started to multiply, and life was born. At the beginning, Earth had very little oxygen in its atmosphere. Indeed, the gases present at that time, nitrogen, carbon dioxide, and methane, would be deadly to us today.

Ozone layer
Unicellular organisms evolved into multicellular organisms. Photosynthesis appeared and living cells started to produce oxygen in large quantities. The interaction between oxygen molecules and ultraviolet radiation from the Sun led to the formation of the ozone layer. This protective layer in the atmosphere is extremely important because it protects all life on Earth from damaging radiation from the Sun. That’s why, even if there was enough oxygen on Mars to breathe comfortably, the lack of the protective ozone layer means we would die from radiation exposure.

Electromagnetic field
Earth’s central core is made primarily of liquid iron and a few other metals like nickel. Mars doesn’t have a liquid core but Jupiter and Saturn also have one. The core rotates with the rotation of the planet and produces convection currents and an electromagnetic field. Earth, Jupiter, and Saturn possess this field which extends far out in space like a bubble and protects the planet from deadly ionized particles from the Sun. Those ionized particles, mostly electrons, shine when ionized and produce the Aurora Borealis and Australis.

Tectonic plates
The continents are located on the surface of what are call the tectonic plates. These formations float above the liquid core of the planet and their movements, caused by the convection currents of the central core, produce volcanic activity, earthquakes, and mountain ranges like the Himalayans, the Rocky Mountains, the Andes, etc. There is a constant remodeling of the planet’s surface because of them. As far as we know, no other planet has tectonic plates.

The Moon
Four billion years ago, a massive object the size of planet Mars collided with a young Earth. The collision sent millions of particles in space which bound together and created the Moon. At the time, the Moon was much closer to Earth than it is now, about 80,000 miles instead of 238,000 miles. At the time, it had a magnetic field and shared it with Earth. This enabled the Moon to act as a protective barrier against the solar wind and the young Sun’s powerful radiation. The Moon was critical in Earth’s ability to keep its thin atmosphere and protect emerging life during this vulnerable time.

In 1687, Sir Isaac Newton explained that ocean tides are created by the gravitational pull of the Moon. There are two high tides and two low tides every 24 hours. Apart from the obvious high and low of the water, there is another important consequence to the tides. Life had to develop ways to live in the water and on dry land. This encouraged changes in physiology and the development of lungs in creatures which eventually were able to live on land.

Finally, the Moon is relatively large compared to other moons in our solar system and it helps to stabilize Earth’s axis and acts as a shield against passing asteroids and comets.

Location. Location.
Earth is fortunate to live in a good neighborhood. Our Sun, at 4.6 billion years old, is still young and this is important because this immense furnace will remain stable for a long time. Indded, the Sun still has about 10 billion years to live. The only problem is that we believe its brightness will increase by 10% every billion years and this will eventually destroy all life on Earth. This means our lease will be up in less than 1 billion years!
Space exploration is in infancy, but we must search for Earth-like planets if we want to survive as a species. Until then, life will continue as usual if we take good care of our planet!
Our close neighbor the Moon is good to us and continues to protect us from being hit by asteroids and other space debris. Our biggest neighbor, planet Jupiter, is also a good neighbor because being so large, its gravity attracts a lot of large rocks, asteroids, etc. and it gets hit instead of us. Some think Earth would not have survived without the protective influence of Jupiter.

On Earth day, April 22nd, celebrate and contribute to keep your planet beautiful. Remember Earth is unique and precious. Each one of us needs to be mindful of its fragility and help take care of it because we will never find another one like it.

Enjoy Earth, your own little planet! Live long and thrive!

A New Year

Hello my friends,

It’s a New Year but COVID-19 is still with us.
Sadly, we have lost Myrtle Beach’s ex-mayor Mr. John Rhodes to COVID. I would like
to offer my sincere condolences to his family and to all who have lost someone dear.

We must all do our utmost to fight this disease. Until a great number of people get vaccinated, we must continue to wear masks, wash our hands, stay at home as much as possible, and avoid unnecessary trips.

Staying at home is not easy so I have a few suggestions for you.

– Listen to your favorite music or dance with your partner.
– Try something new like Tai-chi or yoga with a Youtube video.
– Bake chocolate chip muffins or your favorite cake. My husband
tried homemade pizza dough and it turned out great.
– Reconnect and chat with old friends on Facetime or Zoom.
– Learn to play a musical instrument with Youtube or a friend.
– Find a good book to read. For example, my sci-fi fantasy novel
“I Am Sheffrou”, pen name Cami Michaels is a unique and
engaging story. Now on sale on Amazon.

For my part, I am hard at work on book 2 of the Sheffrou Trilogy.
“Betrayal”, The Color of Treason, a sci-fi fantasy thriller.

I wish you all the best for 2021,
Talk to you soon,


Happy and Healthy New Year 2021!

Good tidings to all on the eve of this brand new year. To all my friends I wish you the best for 2021. Less worries, less sadness, more joy, more celebration!

To start off the year with a bang, my science-fiction fantasy novel “I Am Sheffrou” is on sale for $0.99 until 01/03/21. This unique and engaging story is not one to miss. You can find it now at https://books.bookfunnel.com/freeand99calienromance/mw06s35wi3
