Boeing's "Slow" Progress

After the Boeing Starliner Space Capsule incident, many people looked at Boeing in a negative way, despite their contribution to Space Exploration.  One reason for negativity for Boeing is because of their incident during the Starliner Orbital Test Flight. It was intended to rendezvous with the International Space Station, zooming around Earth at 17,500 mph, but instead, there was a software error that caused thrusters to fire at the wrong time, putting Starliner on the wrong course which caused the failure to rendezvous with the International Space Station. This made SpaceX’s Crew Dragon Capsule the first vehicle to carry humans from american soil since the American NASA Space Shuttle. It is not as easy to get into orbit as flawlessly as people think. Thousands of things have to go right for one system to work, and one simple thing has to go wrong for the entire mission to fail, and during the Starliner Orbital Test Flight, a few things went wrong. Boeing says they are pretty much co

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

Should I use wireless charging or cable charging?

  Many of us use wireless charging to charge our phones. Wireless charging was invented a while ago by Nikola Tesla, an electrical engineer. Wireless charging is easy, simple, and you can quickly throw your phone on a wireless charger to begin charging it. Wireless charging is indeed more simple and easy, but surprisingly, at least to some people, it charges slower than cable charging. Cable charging is faster because it has a direct connection from the energy source, to the phone, charging the battery directly, whereas wireless charging sends low-power signals through the air, creating a delay in charging.  Whether you are charging your smartphone via cable or wireless charging, your battery can get slightly warm. Usually, the battery will become warmer when you are charging via wireless charging and this can cause issues with the battery. The Samsung Galaxy Note 7 was prone to LITERALLY lighting on fire if the battery got slightly too hot. Don't worry, if you have a Galaxy Note 8

How do satellites in space work?

  There are many different types of satellites. The moon is a satellite, a natural satellite, there are also artificial satellites, like the International Space Station, where there are currently 7 humans living. Other satellites include things like communications satellites, internet satellites, and radio satellites. Let's focus on internet satellites to explain how it works. Most satellites use a series of radio waves to communicate with other satellites, or to us here on our home planet, Earth. Depending on how high the satellite is orbiting Earth, your connection will either be slower or faster. If you have a satellite orbiting at a high earth orbit, the satellite will be very far causing your connection to it to be relatively slow, but if you have a satellite in low earth orbit, your connection will improve, by a LOT.  Satellites aren't just always above you, in order for them to remain in space and not fall back down to earth, and burn up in our atmosphere, they must orbi

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

Watch a Delta IV Heavy rocket blast off for National Reconnaissance Office.

The United Launch Alliance Delta IV Heavy rocket will blast off of Space Launch Complex-37 at Cape Canaveral Space Force Station, Florida. The customer for this mission is the National Reconnaissance Office, but the payload is unknown, as the mission is classified. If the Delta IV Heavy rocket lifts off on December 10th, 6:15 PM EST as planned, this will be the 142nd mission that ULA has performed, and the 30th time the National Reconnaissance Office has purchased a ride on a ULA Rocket. This rocket uses Liquid Hydrogen and Liquid Oxygen as fuel, which enables the rocket to reduce pollution coming from itself. As the payload/satellite aboard this rocket is classified, for the National Reconnaissance Office , we do not know much about it, other than it is going to orbit aboard the Delta IV Heavy Rocket. The Delta IV Heavy rocket is the 2nd most powerful operational rocket in the world, right after Falcon Heavy, and Delta IV Heavy is also the biggest operational rocket in the world. Laun

What does the lock icon on a website mean?

Many of us wonder what the lock, sometimes the green lock, on a website means. It is usually to the left of the address to the website. Today we are going to tell you what this means, when it is good, and when it is bad. The lock icon means the connection between you and the web server is encrypted and secure. Meaning it makes it extremely hard for someone to find your connection info, and use it to steal some of your data. The lock icon represents an SSL or a TLS Certificate. SSL stands for Secure Sockets Layer, while TLS stands for Transport Layer Security. TLS is the successor to SSL. TLS is more secure than SSL, and most modern browsers no longer support standard old SSL Certificates, and prefer TLS. It will also show "HTTPS" rather than "HTTP" in the website address if it has a TLS Certificate. HTTP Stands for Hypertext Transfer Protocol, but HTTPS stands for Hypertext Transfer Protocol Secure. Now, if you ever go to a website where you put in information like

Watch SpaceX Launch their CRS-21 Mission for NASA

With the support of NASA, SpaceX will launch its Cargo Dragon 2 spacecraft to the International Space Station on Sunday, December 6th at 11:17 AM EST, and dock on the next day. This launch will mark the first launch of a Cargo Dragon 2, and it will ride atop a SpaceX Falcon 9 Block 5 rocket, which will launch from Launch Complex 39A, Cape Canaveral, Florida. The previous 20 Commercial Resupply Service missions were operated by the Cargo Dragon 1, but the mission will be supported by a Dragon 2 capsule, and the booster supporting this mission (B1058) supported the Demo-2 mission, ANASIS-II mission, and Starlink L12. There are lots of differences between past Cargo Dragon flights and CRS-21. There are 5 unique facts about CRS-21. One of the interesting facts is that for the first time, there will be 2 Dragons docked simultaneously at the ISS (Cargo Dragon 2 and Crew Dragon Resilience), marking the stepping-stone of commercialization of the ISS. Another fact is that the Cargo Dragon’s doc

Proof that we don't live in a simulation.

Many of us believe that we could live in a simulation, and that we most likely do, but there is one fact to prove that wrong. You need to take up mass to store things, even on the most advanced computers in the universe, or, out of this universe. If Space is Infinite, or how big space already is, how can all of that be stored in a simulation? You cannot store infinite data in a simulation, and the "number" infinite exists, but no one has counted to it, even though that is not possible, so the number infinite would not be possible to exist, if we are hosted inside of a simulation. All of the data in every human's brain, nearly 8 billion human brains, on just Earth, would take up an INSANE amount of data, that it would be pointless to even try to store that data, well, at least in our universe. Our universe? What is our universe? Our universe is the region of outer space that is observable, and it is really big. A universe wasn't assigned to us, no one made what we call

What is the Hubble Space Telescope?

A telescope is something you look through that magnifies an object by A LOT, usually. The Hubble Space Telescope isn't an ordinary telescope. It is orbiting Earth at around 17,500 mph, or 7823 m/s (meters per second). The Hubble Space Telescope was launched into a low earth orbit on April 24th, 1990 by the NASA Space Shuttle (Atlantis) and has been orbiting alone since. Vehicles use to service this Space Telescope (only the Space Shuttle), but we do not have any vehicles capable of doing so right now. The Hubble Space Telescope isn't the kind of Telescope that you look through, it contains a computer, takes extremely zoomed in images of stars, exoplants, nebula's, galaxies, black holes, supernovas, and more. It sends these images back to scientists, engineers, and more back here on Earth to observe them and enhance them to make more sense out of them. The Hubble Space Telescope will be replaced with the James Webb Space Telescope in possibly 2021, which will be launched ato

How do numbers make sense?

This might seem like an odd, or even dumb blog post topic, but keep reading and you will see what we are talking about. If I asked you, what number comes before 0, you would probably say -1 (negative one). Why -1 though? You just skipped an infinite amount of numbers, like -0.1, -0.2, -0.3, -03333∞. You skipped the number infinite, literally. How does this make sense? The same goes for the number after 0, you would say it is 1, but what about 0.11111111111111111111111111111111111111, or simply 0.1∞? You can never count past 0.1∞, because the 1 after 0. goes on for, well, forever. Now, if I asked you again what comes after 0, you can't say 0.1 infinite (0.1∞), because that just doesn't make sense, you can't count to infinite. For this reason, we skip to the next major number, which is 2. 2.0∞? Yep, that's what 2 is. The 0 after the decimal point goes on forever, and ever, and ever, and ever. You can't count it, because it's infinite. So what's after infinite?
