An unmanned aerial vehicle (UAV) is an aircraft that carries no human pilot or passengers. UAVs, sometimes called ‘Drones’ can be fully or partially autonomous but are more often controlled remotely by a human pilot. These find applications across many industries including entertainment, military, medical, rescue operations, etc. Drones can be classified as: • Multi-Rotor Drones- These are the most common types of drones. They are used for a variety of applications like aerial photography, surveillance, etc. They are easy to manufacture and are relatively cheap. But they also contain downsides such as limited endurance, speed, and flying time. They can carry multiple payloads per flight. • Fixed Wing Drones- These are completely different in design. They make use of wings which are typically seen on regular airplanes. Unlike multi-rotor drones, fixed-wing drones cannot hover in air. Instead, they move forward on their set course as long as their energy source permits. They can fly at h...

  The Universe is incredibly big and seems full of potential for life, with billions of habitable planets. If an advanced civilization had the technology to travel between the stars, It could colonize our galaxy in roughly 100 million years, which won't be as long for our billion years old Milky way galaxy or even other neighbouring galaxy.   Still we see nothing, hear nothing, the universe seems empty. This is the Fermi Paradox. One of it's hypothesized solution is the dark forest solution. This theory gives a logical explaination why, If there is extraterrestrial life, Aren't trying to make any contact or hiding low under the radar. The universe is a dark forest. Every civilization is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound. Even breathing is done with care. As the hunter sneaks through the dark forest all alone he knows that there might be others like him. H...
