Some myths about space that you need to stop believing in, the number of these myths are huge. But i decided to mention atleast two of them here.
1. The reason why astronauts float in space is because of ‘zero gravity’ in space.
Although astronauts on the space station appear to float freely about their modules, they are in fact plummeting. Fast.
Their bodies, and the space station itself, still feel the inexorable tug of Earth’s gravity, and they fall towards the planet at great speed. Happily, they keep missing.
The spacecraft and its occupants are also travelling sideways at many thousands of miles per hour (which is why rockets never go straight up, but describe an arc). Effectively, the space station is falling around the curve of the planet.
This controlled freefall gives the impression that gravity isn’t there, but it is – about 90% as strong as at the Earth’s surface.
2. ‘Sun is a big hot ball of fire’
The Sun and stars are powered by nuclear fusion. Hydrogen ions (protons) fuse together near the core to form helium.
Put in these tiny atomic terms, that doesn’t sound all that powerful. But the quantities are staggering.
Every second the Sun converts 700 million tons of hydrogen to helium. If you want a horrific comparison, that’s like consuming the mass of every living human, every second.
The Sun, then, is a seething ball of plasma, a hot, electrically charged gas.
That’s two of them, enough for now. I will post about a lot of other myths soon.
Space can be very weird, you can grow two inches in your time in space or your heart can become kinda spherical (atleast that’s what I read). That’s certainly not a reason to not go into space. Although after your return back to earth eveything reverts back.
