A spaceship is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spaceship except single-stage-to-orbit vehi...

Jet engines, which are also called gas turbines, work by sucking air into the front of the engine using a fan. From there, the engine compresses the air, mixes fuel with it, ignites the fuel/air mixture, and shoots it out the back of the engine, creating thrust. A turbofan engine, sometimes referred to as a fanjet or bypass engine, is a jet eng...

In physics and relativity, Time Dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them (“kinetic” time dilation, from special relativity) or to a difference in gravitational potential between their locations (gravitational time dilation, from general relativity). When unspec...

MarsLink.in 2024, Landing Five starships land on Mars, marking the beginnings of the Mars colony. All of the martian rovers sent by different countries before this day. Watch as the five uncrewed starships land and deliver life support systems, these pioneering starships pave the way for humans to land on Mars in two years time, for fishes t...

The butterfly effect is the idea that small, seemingly trivial events may ultimately result in something with much larger consequences – in other words, they have non-linear impacts on very complex systems. For instance, when a butterfly flaps its wings in India, that tiny change in air pressure could eventually cause a tornado in Iowa. The ter...

The immune system is a network of biological processes that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to parasitic worms, as well as cancer cells and objects such as wood splinters, distinguishing them from the organism’s own healthy tissue. Many species have two major subsystems of ...

The respiratory system is the organs and other parts of your body involved in breathing, when you exchange oxygen and carbon dioxide. Parts of the Respiratory System Nose and nasal cavity Sinuses Mouth Throat (pharynx) Voice box (larynx) Windpipe (trachea) Diaphragm Lungs Bronchial tubes/bronchi Bronchioles Air sacs (alv...

A photonic quantum computer could have huge advantages over its matter-based counterpart. Photons are much less prone to interact with their environment, which means they can retain their quantum state for much longer and over long distances. A photonic quantum computer could, in theory, operate at room temperature – and as a result, scale up mu...
