Can humans REALLY colonize Mars?

Yes, humans can colonize Mars, but there are some issues that we would need to get around. Let's say you launch a rocket into earth-orbit, then from there, fired your engines to put yourself on a trajectory to rendezvous with Mars sometime within the next few months. Sure, you can arrive at Mars, and land, as long as you have a heat shield to survive atmospheric entry and engines that you can start up to touch down safely, but you need a way to get back to Earth, and you also need a way to communicate with Earth.

Mars orbits farther away from the Sun than Earth does, so the 2 planets' orbits are not in sync. Mars orbits slower than Earth, so at one point, Mars and Earth will be exactly horizontal from each other, like this image below.

The sun is now in between Earth and Mars, so you don't really have a way to communicate, as our huge star, The Sun, is right in the way for our antennas on Mars to communicate with ground stations or satellites on or around Earth. This means, if there is a leak in your station on Mars, well, you can't tell anyone about it besides your Martian friends. You can fix this with a deep-space/interplanetary satellite network, consisting of thousands of satellites orbiting the sun, all at different orbits to have communication with Earth no matter where you are in the solar system. You send data to one satellite, then it goes to the next one, all the way around the sun until when the last satellite receives the data, it sends it directly to Earth, then, the people on Earth receive the data. There is also a problem with this, #1 it will take some time to get the data all the way to Earth, unless we invent some new method of transferring this data, and #2, it is pretty unreliable, if one satellite misreads data, you will be pointlessly sending faulty data across thousands of satellites just to get the useless data to Earth, without you even knowing anything went wrong.

Ok, that is the first problem, the second problem is, when you land on Mars, you used up your fuel to get in Earth Orbit, put yourself on a trajectory to intercept Mars, and then to land on Mars. You have no fuel left now, and you are basically stuck on Mars. Yeah, that sucks. There is a solution to this, you can use Mars' atmosphere and surface to get Liquid Oxygen and Liquid Methane, a perfect rocket fuel mixture, but you cant steal all of Mars' resources forever, you need a more reliable source, at least until you steal everything from Mars.

We, humans, have experience with sending stuff to mars, we have sent multiple rovers, including the perseverance Mars Rover that was launched just recently launched last year (it is currently 2021), and as of January 31st, 2021, the perseverance rover will be touching down on Mars in under a month. We could do the same thing, except instead of a rover being on top of the rocket as the payload, it can be a human-rated space vessel. SpaceX is working on its Starship Rocket a lot, which its goal is to land humans on Mars. They plan on making Liquid Methane and Liquid Oxygen from Mars to use as rocket fuel to return to Earth, but it is unclear how they will communicate with the people on Mars when The Sun is directly in between Mars and Earth. So far, it looks like they are progressing fast, setting us on a track to reach Mars sometime in 2023-2026. Maybe they will use their fast progressing laser-powered Starlink Satellites to communicate with Earth. With the current rate SpaceX is progressing, you will be able to go to Mars in your lifetime, not just once, but multiple times to Mars and back to Earth.

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
