My Reflection on Space

While reading space I couldn’t help but remember all of the ways that space has been exposed to me throughout my life, whether be from space documentaries and school to Star Wars and Doctor Who, I have grown to find Space and its infinite expanse quite fascinating. Something cool that I happened to learn was from one of my favorite YouTube science channel, Vsauce. In this Channel, Michael explains many science questions that we sometimes wonder about. The video in question that I watched was “Travel INSIDE a Black Hole” where Michael explains various things about black holes, but what interested me the most was when he talked about how it would look like to a person who is watching someone else enter the black hole. Basically, As the person who is traveling at the speed of light approached the black hole, they would appear to slow down rather than speed up. The gravitational pull of the Black Hole is so powerful that even light cannot escape. And since gravity also affects light, time slows down due to light not being able to escape the black hole. The person who approaches the black hole would go on just fine as if nothing had happened, and at some point they would cross the ‘event horizon’, which is basically the point of no return, where they will at some point have their molecular structure stretched paper thin. At that point no one really knows if something other than death awaits possibly on the other side of a black hole, there are only theories. I always love thinking about these mysterious parts of space, it really makes you wonder about all the stuff thats out there, in space.

If you want to have a better explanation of black holes, I will leave the video I watched just below.

For my space blog I decided to focus on the Challenger Space Shuttle Disaster. This terrible accident happened on January 28, 1986. Within 73 seconds after liftoff the shuttle exploded which killed the seven crew members on board. The temperatures the day of the launch were considerably low but NASA continued with the launch. This was why it exploded, the cold weather caused a degrading on the seal of the solid rocket boosters that help to bring the ship into orbit. This launch was heavily broadcasted because it had one of the first teachers going into space and she planned to give lessons from space. Even my parents remember watching the whole thing going down on tv and being in complete shock when it exploded. It was a very tragic event. I also did a little research into the space exploration where they landed on the moon for the first time. The first man on the moon was Neil Armstrong. He took his first step on the moon July 20, 1969. Also on the mission were astronauts Edwin Aldrin and Michael Collins. The name of the flight that brought them to the moon was called Apollo 11. Space exploration missions are super cool because then we come back with more knowledge about what is up there since we know very little about space since it seems to go on for infinity but it can also be very dangerous.

Space Reflection

I can never wrap my head around how large the universe is and how we are looking back in time while looking at the stars. The speed of light is 299,792,458 m/s or 671,000,000 mph. Since light travels so quickly, we don’t experience delays in everyday life. In comparison, the speed of sound is 343 m/s or 767mph. Think of the delay that happens between lightning and thunder. If a storm is far away, there will be a greater gap between the lightweight and the thunder we hear. If a storm is close, there is a small or even nonexistent gap. However, the universe is so huge that we are viewing what some stars looked like millions of years ago. A light-year is the distance light can travel in a year which is roughly equivalent to 6 trillion miles. Icarus (pictured below), the farthest individual star that was ever visible, is 9 billion light-years away from earth, which means when someone views the star, they are looking at how Icarus looked 9 billion years ago.
