space.

we're in it.
 some of us don't even put any thought into the wonders that the laws of physics have created. some of us spend our lives playing roblox. since i was a tiny annoying kid I always loved space. The idea that we could go out of our globe and explore other worlds was astonishing. As I grew i discovered that space exploration was scarier and more complicated than what I once thought. The possibility of dying while in the process of going to space is really high! Oxygen is scarce, pressure is almost nonexistent, the temperature is low, nobody can hear you. Basically everything including your spaceship can kill you. Even with that knowledge in hand, I still would love to go to space, specially because of how deadly it is. Knowing that a simple alteration in some properties of the ship, or a tiny malfunction might blow me up, it makes me admire that thought even more. I think that the idea of dying in space, being scattered through the vacuum where there is nobody to hear you, is what makes me so attracted to the subject. After all, we are so insignificant. When on earth, we fit quite nicely to this scale. But when in space, we truly understand that we are simply microscopic thingies when compared to the wholesomeness of the cosmos. We don't know what is out there, but we thrive to discover what lies within the void of our universe. Some of us don't, sometimes due to fear, or just simply because of pure ignorance!
Sometimes I like to think about the speed of light (299792458 meters per second, if you're american just google it on miles or some shit idgaf). The light that the sun irradiates takes around eight minutes to reach the earth's surface. So, if the sun were just to magically stop shining, we would only understand that 8 minutes after it happened. That makes me think. Telecommunications. They are based around light emissions. NASA wants to send humans to mars, but if we calculate it, the thought of being there is scary (ignoring all the dangers that space kindly offers to us).Why, you may ask. Here on earth we can use the internet to talk with each other, at a staggering speed! Skype, whatsapp, and other apps, we use them to speak and see each other , and we don't even notice the lag due to the short distance that the light that encodes our data has to go through. Now imagine that you successfully finished your trip to mars. You are now installed in your new artificially pressurized martian "home". You feel that now is the adequate time to communicate the people back on earth about your success. So you get to the communication station and speak. You would expect a human to respond something after a few seconds, but nothing comes through the speaker? You might think you are alone, that they left you there. Thing is, any type of data that is sent from mars will take around a minimum of 3 minutes to reach earth (you obtain this result by dividing the minimum distance between the earth and mars by the speed of light, and then divide it by 60). You can obtain the maximum and average lag times by getting the distances and repeating what I did. Imagine saying hello, and only getting an answer more than 3 minutes later. That's a current issue with space exploration on a human level. If for some reason our spacecraft exploded, or we had any issue that needed quick examination from ground control, they would only receive said data too late. Of course, this issue can be fixed, by finding something faster than light ( which would require adjustments to general relativity ). Quantum entanglement sounds like a nice solution, ( check this out:https://www.sciencealert.com/scientists-have-achieved-direct-counterfactual-quantum-communication-for-the-first-time ). This is endearing. To be honest I don't know. Das ist alles,
