The most innovative technology in the 21st century.

As of the 21st century, SpaceX operates one of the most innovative technologies, or perhaps the actual most innovative technology, for their reusable rockets. SpaceX's Starship which is currently in development as of September 2020, is a fully reusable rocket.

SpaceX Starship Booster and Spaceship

When the entire rocket reaches space, the first stage/booster stage will obviously detach from the spaceship part. It has enough fuel left to literally fire up its engines to perform a re-entry burn to slow it down before fully re-entering the atmosphere, and then performing a landing burn to land right next to the launchpad where it launched from, to be re-used.

The actual spaceship itself, which is still in space, now in Earth Orbit, will wait there in orbit, while the booster gets ready to launch again, with a Starship Tanker on top of the booster, instead of the spaceship. The Starship Tanker will launch to orbit, just like the actual spaceship did on top of the same booster, and they will attach to each other and the tanker will refuel the spaceship, so it can depart for the Moon, Mars, and beyond. The booster will land AGAIN to be reused for another tanker for another spaceship, or another spaceship, repeating the entire process, depending on the destination for the spaceship.

This is the most innovative technology on Earth. Well, and Mars. Venus and Mercury too, all of them! Feel free to click here to watch the Starship Launch animation to see what we just talked about in action.

Starship SN10 Aborts at T - 0 Seconds for its 10km test flight.

  Moments ago, Starship SN10 attempted a flight to 10km, to then orient itself into a unique horizontal bellyflop position, flip itself upright after it has descended to about 1km, deploy the landing legs, and touch down on the landing pad softly. This vehicle, Starship Number 10, uses Liquid CH4 (methane) and Liquid Oxygen aka LOX/LO2, used by its 3 powerful Raptor engines.  Today, SpaceX started their official stream for the Starship SN10 Flight. SpaceX have privated the stream replay, so we cannot replay it. In case you want the link: The vehicle began fueling up with Methane and LOX, and then shortly after, it started the engine chill process, which is the process of chilling the engines down in preparation for engine ignition, so the engine material does not crack or get damaged from sudden shock. The vehicle attempted to start up its 3 Raptor engines, by opening the fuel & oxidizer valves, starting up the turbopumps, sho

What is “the best” programming language?

Programming languages, there are so many of them. Some programming languages are way easier to learn than other ones. But which programming language, is “the best” programming language? This question, it is not really answerable. There is no “best programming languages”, they are all meant for different things, well, MOST of them. If I were to compare 2 different programming languages, meant for very similar things, like Batch and Bash, I would say Batch is easier, as its Syntax is not as confusing as Bash’s to the average person. Here is another example, C# is primarily used for computer applications, mostly on Windows, and HTML is a markup language, being used to make websites. I cannot compare C# (it is pronounced “See Sharp” if you didn’t know) because they are used for completely different things. It wouldn’t make sense to say, “C# is way better”, because what is it better at? Developing desktop applications? Sure! Then I can say HTML is better at making websites, it is not a logi

How do you know the universe was not created a few minutes ago?

       The universe is the giant area of space that we live in, which is observable. Anything past our universal border is not in our universe. People do say the universe is constantly expanding, but there is no proof of that, as the "imaginary" or, maybe not imaginary border at the "end" of our universe. But, how do you know that the universe even exists? Were you even in it last week? Did last week even exist? Last week, the universe could have been created, and you do not have proof against it. All of your knowledge and memory could have easily popped into existence a few seconds ago, tricking you into thinking you have existed for longer than you think. This is likely, but also unlikely, it is a 50/50 chance. A reason that this is unlikely is, there are a lot of things that do not make sense in our universe. Like, why does matter attract matter, resulting in gravity? This exists in our universe, but can it exist in a different universe? Not really, or most likel
