We Don’t Know Why Astronauts Get Motion Sick
Переглядів 70 тис.Рік тому
A majority of modern astronauts experience any one of a suite of symptoms scientists collectively call Space Motion Sickness, or SMS. But despite knowing about it for nearly as long as humans have gone into space, we still don't know exactly what causes it, or how to predict which astronauts might lose their lunch.

The Biggest Star In The Universe Is Too Small
Переглядів 124 тис.Рік тому
R136a1 is the most massive star that astronomers have ever discovered. It's so massive you might think the laws of physics wouldn't allow it. But it turns out that its current mass estimate is actually so low that it threatens our understanding of how the universe got to be where it is, today!

    The question is what happened to that matter it's sucked into the black hole and what really comes out at the other end of the black hole that's what the people probably want to know and I believe what really comes out at the end the black hole it is a new creation that's why the universe it's internal

    I've had this thought about those Aliens in "Edge of Tomorrow!" Those super "fast" Aliens would have had to evolve on a planet, orbiting a star, that itself and its accompanying planets, orbit a black hole! That entire solar system would be moving at a percentage of the speed of light. Anything evolving there, to the molecular level, would be doing so at a relatively "faster" rate. Take "them" out of their relative "space" and put them in ours, they would appear to "move" at dizzying speeds, to THEM "we" would appear to be practically sitting still/idle. On their perspective they're just moving at THEIR relative "normal" speed as we're moving through our space. They'd be wondering why we're so, "easy to kill" because we're so slow again, relatively. Fascinating thoughtful stuff..lol❤

    Honestly... I think your ryt... I have a feeling that this "earth" we live on is an EYE!!! As above so below! The outer of an eye has its lens behind the pupil there is another lens as above so below. If you research about what the eye is how it works. You can see the cell tissues have resemblance of all the mega structures.. if it is an eye the the world is flat it's also a sphere. And it's also a simulation... the ice wall around the iris is where the white starts for and eye... the pyramids were never made they are topped with quartz just like a human eye when dried up. The pyramids our the inner working of an eye that allows light and vision ... the inside of the pyramids are not tunnels but the space for the eye to be able to receive the light giving vision. Hence we are a similation. I'm eye sight vision is flipped upside down but the brain flips it right side up. Giving us gravity because we are upside down but don't know it. The dome is the lens and the sun is the light reflecting off the inner lens behind the eye.. that's why it looks like it does when an eclipse happens we are literally seeing light enter the eye!! Research and compare it all and let me know what you think please... the all seeing eye...

    We are mission-crazy on the fate of the ISS. In Norway, they have built a vault in a mountain holding every seed known to the earth. We should realize that the ISS would be an ideal back-up system for how many generations it will be down the line when the earth encounters an extinction event and when they go to the vault in Norway after its time to re-wild the planet only to discover that all the seeds have not survived because of rodents and seepage, etc. Let's be clear on this: Fill the ISS with all the seeds of the earth and while your at it, with the DNA of every creature, insect and reptile and the like and send the aging space station on a slow trip to Saturn where it will orbit the ringed planet until it is needed.

These examples are robotic advances and medical testing advances, they have nothing to do with sending people to Outer space. NASA is the biggest waste of money!!

    I've recently found it odd to think about "falling into a black hole" and the upsetti spaghetti, because a black hole for all it's darkness and density is still a star, right..? I don't think anyone would contemplate being near the surface of a star because it's obvious you would be vaporized in the corona. Yet, we seem to think that the blackness makes them more, what, solid? Less inferno like? There is a huge glowing ring of gas before you get to the event horizon. You would be a glowing gas long before any spaghetti gets upsetti, yeah..?

Sci Fi sometimes makes black holes seem like cosmic vacuum cleaners that keep consuming and growing more and more stars so when I heard our entire galaxy is literally revolving around a supermassive black hole that idea got me kind of worried. Took me a while to figure out but basically just like we orbit our sun in our solar system in a stable orbit the same is possible around a black hole
