Everything about space, rockets, relativity and quantom mechanics is absolutely mind blowing. Just the numbers in themself are just so massive in their scale, wether big or small, that I can't help to feel amazed every time I read one.
That is just the numbers though. The ideas and how the universe works are even more mind boggling. The idea that time travel isn't just possible, but something that happens to practicly everything in the universe, or that particles can exist in every position in the universe at once. These are ideas that play with our preconceptions of how the world works, and spits in their face.
When I talk to Someone, when I give them my standard go to explanation of space, which still boggles my mind. The general reaction is just 'that's cool' even though I just told them they are looking thousands of years into the past when they look at stars in the night sky ( not strictly true, but, true somtimes)
I just don't understand how this wouldn't boggle people's minds. Completely shattering their preconceptions about how the universe works, that they are looking at things in the sky as they where hundreds of years before they where born, it just means nothing to them.
Maybe it isn't the facts, maybe the way in which I present them. I can be like that, I know. But but... it is just so awesome. I can't think of a situation where it wouldn't be something that someone wouldn't be interested in.
Maybe I am overly obsessive. Yes, yes I am overly obsessive. Still, what I say I think holds true.
To end it off, here are some facts that if you want you can completely ignore.
-light travels fast, but in the scale of the universe, not that fast. It takes time for light to travel from one point to another, so long. One of our base values in astrophysics in the lightyear, the distance in which light travels in a year. When you look up at the night sky, you are looking at light that has taken years to melenia to travel to us. When you look up at that random faint star on a good night. You are looking hundreds if not thousands of years into the past. With the right telescopes, you can look billions of years into the past from your own back yard.
Gravity, speed, and energy can all affect how time works. If you are traveling near the speed of light, you would be experiencing time more slowly. You feel the same in your ship, but for every second that passes for you, a year could pass for people back on earth. Gravity has an affect to. The closer and closer you get the the event horizon of a black hole, the slower your time becomes relative from someone far away. To you, you fall into the black hole, and everything feels normal, except for the gravitational forces ripping you apart. From an outside observer, the closer you get, the slower you move, until you stop on the edge of the black hole. Then you stay there for infinity. While you fall into the black hole, the universe will speed up to the point in which hypothetically, and infinate amount of time passes in the outside universe before you fall in. For you, you fall in and you die. To the person watching you, you never fall in. Different observers see different things happening to a person or object. Something might happen for you, but might not happen to someone else. There is no correct answer even though both of you observed completely different things happening.
The main liquid engines for the retired space shuttle, the RS-25s use powerful pumps to pump fuel into the engine chamber to be ignited. The use two pumps, a 'low pressure' pump that compresses fuel to 450 psi (your car tires are 40 psi) then a high pressure pumps, that pushes the fuel into the combustion chamber at pressures exceeding 2000 psi. They pump around 500 pound of fuel a second with a combined horsepower of 30,000 horsepower. Near 30 times more powerful than the buggati veyron. All that for one type of fuel. So they had another pump to pump the oxidizer as well.
Temperatures in the combustion chamber reach near the melting points of metal. Is order to cool the bells and chamber, they used the exhaust from the turbopumps as coolant even though it was facemeltingly hot to begin with, and also using the supercooled fuel by pumping it through tiny holes in the bell or nozel of the rocket.
One RS-25 can lift 550,000 pounds. The equivalent weight of 50 elephants strait up into the air.
Ok, completely divulged into my interests and gave an information dump. Who cares, don't like it don't read it. It was fun to just write about. Like seriously though, how could you not find this stuff cool? Serious question, if you don't i would love to know why.
