Science fiction stories do come true all the time. Less than a hundred years ago, space travel was a fantasy invented by storytellers such as H G Wells and Jules Verne. When we consider the extraordinary advances made in the fields of travel and communications in the past century, it is tempting to believe that Star Trek may in the future be nearer to reality than at present seems possible!
Science fiction introduces us to elaborate, futuristic worlds that often sound like nothing more than a dream. But humanity has made incredible technological advancements over the past 100 years, and many of the ideas predicted in science fiction have now become reality.
Some predictions, like self-driving cars, are still in the early stages, but scientists and engineers have reached many other milestones first described in fiction, such as bringing people to the moon.
In 1865, author Jules Verne released From Earth to the Moon, which described three Americans’ mission to launch a spacecraft and land on the moon. Parts of the novel were similar to the first real moon landing, which occurred 104 years later.
Both the NASA astronauts and Verne’s characters launched from Florida. NASA’s command module was named Columbia in another similarity to Verne’s fictional spacecraft, the Columbia. NASA astronauts Neil Armstrong and Edwin “Buzz” Aldrin succeeded in walking on the lunar surface in 1969 while Michael Collins remained in the spacecraft. The three men in Verne’s novel, however, never stepped foot on the moon.
NASA has acknowledged other similarities between Apollo 11 and Verne’s novel as well. For example, the space agency said the Columbiad’s shape and size closely resembled the Apollo spacecraft. The novel also claimed a telescope would be able to see the Columbiad mission’s progress. When an explosion caused a malfunction during the Apollo 13 mission in 1970, a telescope at Johnson Space Center was able to see the accident, which took place more than 200,000 miles away (300,000 kilometres).
3D holograms have been featured in sci-fi for decades. In 2017, an Australian company claimed it has managed to produce a hologram table that resembles the futuristic holograms from the original “Star Wars” movie. Princess Leia called for Luke Skywalker’s help using a holographic message in the 1977 “Star Wars” movie. Since then, scientists have worked on turning this technology into reality.
Euclideon, an Australian company, says it has made the first multi-user hologram table in the world. As many as four people can interact with the hologram at once using motion-tracking glasses. Though Euclideon’s invention has been met with some scepticism, but New Atlas reported in November 2018 that the company is moving forward with bringing the hologram technology to market.
“Star Trek” featured replicators that could 3D print food and everyday objects in a few seconds. Scientists are now using 3D printing technology to make objects out of plastic, metal, and glass, though the process is not nearly as fast.
The New York-based nonprofit Mattershift says it has developed carbon nanotube membranes that could separate and put together individual molecules.
Forbes reported that Mattershift CEO Rob McGinnis says the membranes could help scientists make anything out of a set of basic molecular building blocks. “We’re talking about printing matter from the air,” McGinnis said, according to Forbes. “Imagine having one of these devices with you on Mars. You could print food, fuels, building materials, and medicines from the atmosphere and soil or recycled parts without having to transport them from Earth.” In addition, startups like Natural Machines are working on making 3D food printers commercially available.
The Iron Man suit has become legendary since first appearing in Marvel Comics. People won’t be flying around in suits anytime soon, but the US military is developing high-tech suits that will mirror some of Iron Man’s capabilities. The military’s TALOS program – short for Tactical Assault Light Operator Suit – aims to enhance human combat.
TALOS will take in huge amounts of data from drones, naval sensors, and reconnaissance aircraft to better inform soldiers, Military Times reported. The suit is expected to be light and include life support systems that will track soldiers’ vitals. 3D sound pickups built into the suit will also help soldiers figure out where incoming fire and vehicles are coming from.
It takes millions of years to make a fossil. An animal dies. Its body sinks to the bottom of a lake. Sand and silt cover its body. The flesh rots away. Minerals seep into the bones and turn them to stone. The animal is now a fossil. The fossil is found.
Just over 100,000 years ago Homo sapiens appeared. The name means ‘wise man’. They were modern humans. In Europe they lived during the freezing Ice Age, a time when glaciers covered the land. The Ice Age ended 12,000 years ago.
The first people we think of as humans appeared in Africa. About two million years ago, Homo habilis (handy man) appeared. Then, more than one million years ago, Homo erectus (upright man) appeared, but they weren’t modern humans.
