All of Us Are Dead

Best Sci-fi Series on Netflix

Released in January 2022, this show has become a favorite of Sci-Fi lovers. Produced in Korea, All of Us Are Dead involves a group of students who are trying to fight off a zombie virus. It shows the courage and fight of the students who must deal with a zombie invasion and still come out of the school alive. With a huge worldwide fan following, this show mostly takes place at a high school when a zombie apocalypse happens. The outbreak is naturally caused by a failed science experiment (those damn scientists!), and the students are trapped without food and water. Even the government has cut them off! This coming-of-age zombie tale stars Yoon Chan-Young, Park Ji-hu, and Jeon Bae-soo.

Alice in Borderland

The premise of Alice in Borderland is similar to that of Squid Game, in which a group of people found themselves involved in a dangerous life-or-death game. Various characters are stuck in an abandoned Tokyo and must complete every challenge to win as many cards as possible. Each card has a number that indicates the total remaining days the players will stay alive before they must collect another card.

Lost in Space

In 2046, humanity is on the brink of extinction. It is now the Robinsons’ turn to take an interstellar journey and join an established colony in the Alpha Centauri system. They are unable to reach the colony because the spaceship is attacked by aliens. As the family evacuates the ship using a smaller spacecraft, they inadvertently enter a wormhole and crash-land on an Earth-like planet. Thanks to a balanced mix of family drama, space adventures, and memorable villains, Lost in Space is a promising reboot of 1965 original.

The 100

Throughout seven seasons, The 100 continues to deliver shocking plot twists and an enticingly rich world-building storyline. Viewers follow the journey of a hundred delinquent juveniles, who have been sent from a space colony to Earth. Those teenagers are all space-born, and the entire planet is considered a hazardous zone due to a nuclear disaster almost a century ago. As it turns out, adapting to the environment is the least of their problem. Some people actually survived the apocalypse; their descendants now live in cult-like societies, including cannibals. The 100 find themselves involved with the conflicting parties.

Sweet Tooth

A half-human half-deer boy is navigating through a post-apocalyptic world. Despite having a 10-year-old boy as one of the main characters, Sweet Tooth tackles some intense mature themes like greed, hatred, and loss along the way. Think of the story as a fairytale geared toward adult viewers. Based on a DC Comic series, the adventures deliver an enjoyable blend of fanciful drama and a generous dose of excitement. There is only one season, consisting of eight episodes.


Right around the time that NBC cancelled Manifest after three seasons, Netflix brought the series to its streaming platform, and it has been a big hit since. The story starts with a flight that undergoes some massive turbulence before finally making a safe touchdown at Stewart International Airport. On the ground, the passengers and crew learn that they have been presumed dead for more than five years. They unknowingly disappeared into the turbulence, and now they are back with many baffling questions.

The OA

A blind woman named Prairie Johnson has been missing for five years. She has now returned and has shockingly regained her ability to see. Johnson tells everyone she is the “original angel,” sharing stories of abductions and escapes. Instead of reporting her ordeal to the authorities, she takes matters into her own hands and assembles a team to save the other missing people. The only way to the rescue is through a portal that leads to another dimension.

The Umbrella Academy

One of Netflix’s original series, The Umbrella Academy is based on a comic book series of the same name by Gerard Way, illustrated by Gabriel Ba. It tells the stories of seven children with extraordinary powers. They are now on a mission to figure out the mystery surrounding their father’s death and save the world from an impending apocalypse.


Thousands of people from the future have their consciousnesses sent back to the present, so they may prevent the collapse of human societies. Since their physical forms are still in the future, they must inhabit the bodies of present-day individuals to complete the task. Although a time warp is hardly a new sci-fi concept, Travelers should feel refreshingly different thanks to the tricky double-life premise.

Stranger Things

Check out our Stranger Things quiz.

It would be blasphemy to make a list of the best sci-fi series on Netflix without having Stranger Things included. The stories of El and a group of misfit teenagers in the fictional town of Hawkins, Indiana are among the best Netflix has to offer. No one is safe from the relentless threats of monsters originating from the town’s alternative dimension. Events in the series are set in the 1980s, showcasing a detailed nostalgic glance at the trends and popular culture from the bygone decades. In fact, it is the series’ old-fashioned look and feels that keeps everyone coming for more. The series has concluded its fourth season and is up for another and final chapter.

What are the long term effects of space travel?

According to nasa.gov, there is an acronym they use for the five stressors of space travel: RIDGE.

  1. Radiation-On Earth we are somewhat shielded from radiation by our atmosphere. But in space, astronauts are exposed to all kinds of different levels of radiation. This exposure can cause an increased risk of cancer and degenerative diseases.
  2. Isolation and Confinement-Astronauts are trained so they will be able to work for six to 12-month missions. But getting ready to head to Mars will need more preparations. Sleep schedules, heavy workloads, boredom, and missing loved ones are the things that NASA knows need to be developed for safe and successful missions.
  3. Distance from Earth-The Space Station orbits 240 miles above Earth and the Moon is 1000 times further. Important things to consider are having enough food and medicine. This can be delivered to the Space Station, but going to Mars will require everything to be on board.
  4. Gravity Fields- “Astronauts will encounter three different gravity fields on a Mars mission. On a six-month trek between the planets, crews will be weightless. While living and working on Mars, crews will be in approximately one-third of Earth’s gravity. Finally, upon returning home, crews will have to readapt to Earth’s gravity.”
  5. Hostile/Closed Environments-Microbes can change characteristics in space and micro-organisms can be transferred easily in closed spaces. This could lead to more allergies and other illnesses while in space. Every inch of the environment has a very well-thought-out design so it’s not too hot or cold, and the right lighting and the right amount of space for each astronaut to work.

Go to nasa.gov for much for the information about space travel. It’s a very interesting read.

How will robots change our lives in the future?

According to rd.com real robots will take on a larger role in the coming years, thanks to the advancements in robotics. Artificial Intelligence (AI) will be a real game changer. Martin Ford, author of Rule of the Robots: How Artificial Intelligence Will Transform Everything states that AI will eventually evolve so that it will be a utility just like electricity is today. It will become so inexpensive that anyone can use it to solve just about any problem you may have.

What is a robot? Any automated machine that can replace human effort. Think of classic shows like The Jetsons and Star Wars with robot maids and bleeping droids to help you with everyday needs. We are already using a robot if you have a robot vacuum cleaner or an interactive robot pet.

There are many pros and cons when we think of the future of robots in our lives. Go to rd.com to read about them and more about robot technology. You will want to buy your own robot! The article is called How Robots Could Change the Future by Scott Steinberg (Oct. 13, 2022).
