how does zero gravity work??

 1. Zero gravity works better than normal gravity

 You can get yourself into some pretty weird positions while floating around in free space or even just sitting still on Earth's surface. With no gravity at your back, your muscles are forced to do their jobs without any assistance from gravity. This makes them stronger and helps prevent injuries caused by muscle breakdown. Your joints are also healthier because they don't have to bear the weight of your body as much.

 2. You can sleep anywhere

 If you've ever tried sleeping in bed with someone else beside you, you know that it's hard enough to fall asleep. If you're floating around in a spaceship, though, you'll be able to drift off instantly. That means you'll be able to rest anywhere in the ship—including chairs or couches—and not worry about waking anyone up.

 3. Zero gravity is great for exercise

 When we think about exercising in zero-gravity conditions, the first thing that comes to mind is running on treadmills. While this might be fine if you enjoy running, it's actually rather boring compared to other types of exercise. When you're in microgravity, there's nothing for your legs and feet to grab onto, so they're completely unsupported. This forces your body into different movements, like swinging your arms, twisting your torso, and jumping up and down.

Zero gravity works by slowing down your heart rate. In zero gravity, blood moves slower through your veins since there are no objects against which they can move, thus causing less pressure on your heart while still allowing blood to flow at the same level. This means that the oxygen content in your blood remains constant; however, this is not enough to keep the cells alive. Your body may live under zero-gravity conditions for several days but after a certain period of time (about 20 hours) your body begins to die from lack of oxygen. The reason behind this is that your heart beats faster to compensate for the lack of movement.

Exoplanets holds a better survival than Earth

 Exoplanets holds a better survival than Earth ■Exoplanets are those planets that have a rocky surface like Earth, Mars etc. and found outside our solar system.  We have heard a term SUPER - EARTH A Super earth is  an extra solar planet with a mass higher than our earth but lower mass than " ice giants" such as Uranus, Neptune. examples of super earth are COROT - 7b{ICARUS}, GJ1214b{SHESHA}, KEPLER - 440b. ■  Reasearchers had already discovered many planets similar to our mother EARTH but very recent studies has opened up new mysterious facts revealed "these SUPER - EARTHS full of Hydrogen and Helium. Featured Articles  💙 Mission Mangal ■SOME FACTS ABOUT HYDROGEN AND HELIUM 1} HYDROGEN - ●Most abundant element on Earth. ●Alternative fuel source [with a very high energy] ●fuel cells in rockets or gasoline powered cars. 2}HELIUM - ●Second most abundant element in the universe. ●used in air balloons. ●source of energy of sun and stars. ■These exoplanets  ...

Research: The mass of a black hole is 4.4 times the mass of sun | Binary systems | black hole - ISC

 Research: The mass of a black hole is 4.4 times the mass of sun|Binary systems|black hole NASA  and European Space Agency(ESA) for the first time measured the mass of a black hole moving in space with the one and only The Hubble Space Telescope (HST). Until now the mass of a black hole determined on the basis of position of binary systems or galaxies. Large black holes were belived to occur only with companion stars , but for the first time a single black hole has occured .  The discovered black hole is believed to be about 80 light years away from our galaxy. Earlier it was estimated that it is 5000 light years away. Stars increase its mass by interacting with another star or its comapnion star. When the mass increased it explodes called Supernova.  Remants called as 'neutron star'. When remanant is bery large it is called "black hole".  According to scientists the mass of a neutron star is between 1.6 to 4.4 times the mass of sun. The discoveries till n...
