The simulation hypothesis is the proposal that all of reality, including the Earth and the rest of our universe, could in fact be a computer simulation. Nick Bostrom popularised this idea in his book “Are You Living in a Computer Simulation?” published in 2003. It has captivated many popular scientists and innovators such as Elon Musk [interview]and Neil deGrasse Tyson[Isaac Asimov Memorial Debate].
However, the idea is not novel. It appeared in many movies like the famous Matrix (1999). I especially like the Ship in a Bottle (S06E12) episode of Star Trek: The Next Generation (1993).
The Enterprise spaceship is…
Qattara Depression is in Egypt. Its deepest point is about 130m below the sea level. The idea was using that as an advantage firstly brought in 1912. The multiple different project proposals were considered: Using the elevation distance as a hydro plant or divert Nil river to establish freshwater Qattara Lake. That would make this part of the Sahara Desert habitable. However, the cost of building a canal or tunnels was extreme. The proposed solution to use 213 nuclear bombs (every 1.5 millions of TNT) for the land extravasation was quickly discarded.
However, we could use the advance in the…
COVID-19 makes more than 30 million people unemployed just in US within weeks. That’s about 20% of US jobs. Artificial intelligence (AI) might be as significant as COVID.
Yet, there is a key difference between COVID and AI. Most of the jobs lost due to COVID might come back after the quarantine restrictions are released. That will not be the case of AI. The average expectation is that about 35% of jobs would be replaced by AI software within the next 10 years.
About a year ago, I wrote an article on using a large fleet of solar sail spacecraft to compensate for the released CO2. It seems to be far the cheapest option to save our planet of the effect of Global Warming. However, that is not the only benefit. We could use them for interstellar travel.
The fleet of solar sails probes to combat Global Warming will need to cover 1.2 million sq. km. That represents the power of about 10 TW ~ 120.000.000 Newton force provided by solar radiation (assuming F slightly higher than 9.08 μN/m2 at 1AU — the…
Physics defines sound as a vibration that propagates as an audible wave of
pressure through a transmission medium such as gas, liquid or a solid. Most of the sounds we hear are generated from solid materials, including human speech. Although we need to breathe in order to speak, the muscle tension of the vocal cords must be precisely managed in order to generate the voice.
If humans happen to hear a strange noise, such as an iron spoon slowly moving on the glass or a low frequency roar from a distance, this can cause the body to automatically respond with…
Back in 2016, I visited CEBIT conference in Hannover. It was full of so called “smart” things which I did not find smart at all. This “smart” things hype included, in fact, many just “connected” devices that in most cases, delivered a single purpose, narrowly defined benefit to the user.
A few examples I still remember:
Almost 10.000.000.000.000 kg of CO2 is every year released and mainly stays in the atmosphere. We increased the concentration from 300 ppm to more than 400 ppm during the last hundred year. And we will most likely double it before we move to CO2 neutral methods of energy production.
So, can we even avoid the negative consequences of the released CO2?
Despide all negative news on global warming, I see one viable option to save our civilization. But we need to change our thinking in two ways: Firstly, we need to start using tools of 21st century and secondly, we…
