Could The Sun Rotate Around The Earth + Other Big Space Questions

Thickness and muscle size With little vegetation, standing upright wouldn't be as necessary to find predators around us. We wouldn't be the fastest runners either, but we'd be strong enough to fight off a pack of odd-looking wolves. If the Earth was supersized, it's possible that different species of humans would be roaming the land in isolated areas. This would have delayed the Bronze Age and modern civilization as we know it.

Today's thinkers, but some would still hold true, claim that there is a pen out there that can function in zero gravity, extreme temperatures, and even underwater. They claim that this pen can ride on almost any surface, even if it is turned upside down or when the surrounding temperature reaches 570 degrees Fahrenheit.

They also claim that NASA spent millions, if not billions, of dollars over the course of almost a decade to develop such a pen. The issue with ballpoint pens in space is that Since gravity has no effect on it, the ink cannot ordinarily flow to the ball; instead, pressure is created in the ink reservoir.

and pens began to leak some time ago. The Fisher Pen Company in Chicago, which Paul C. Fisher founded, sponsored the development of the pressurized ink cartridge, which NASA did not develop despite rumors to the contrary. Paul C. Fisher spent more than $1 million over nearly ten years to create the pressurized ink cartridge, which was used by NASA, but wooden pencils were thought to be a fire hazard in most spaceships at the time because the atmosphere inside them was 100 percent oxygen.

Intriguingly, rumors about NASA spending an absurd amount of money on the development of space pens have been circulating for decades. They have been refuted numerous times, but they still persist. The pen was patented in 1966 and after conducting several thorough tests NASA started to provide Apollo Astronauts with such pens.

Because there is no air in space, it is an almost perfect vacuum, and sound waves cannot travel through a vacuum to cause your eardrums to vibrate and send signals to your brain. However, this is a good thing, especially for astronauts on spacewalks, if something goes wrong. Many science fiction films can lead you to believe that everything happening in space is accompanied by some kind of sound effect, which is a completely false assumption.

They typically spend a lot of time away from stars where, in the gloom of space, they remain mostly motionless and still. The only time that frozen comets develop tails is when they approach a star and begin warming up. During this process, they develop a distinctive tail that always points away from the star that influences the comet. This occurs because the tail is blown in the opposite direction by solar wind.

sunlight and solar winds Because of this, the tail of a comet is frequently in advance of it rather than following it. Now, let's consider what a light year is. This idea leads us to feel that we are talking about time here, yet light years actually measure distance.

This is how a light year is defined by NASA. the total distance traveled by a light beam traveling in a straight line in a year; given that light travels at 186,000 miles per second, a light year is equivalent to roughly 6 trillion miles. Hey, calculate.

People frequently assume that there is no gravity in space, which accounts for the weightlessness astronauts on the International Space Station experience, but this is not exactly true. Gravity is one of the most significant forces in the universe because of it, the moon can orbit Earth and the sun doesn't float away from our home Milky Way galaxy. However, the astronauts on the ISS only experience microgravity, which is very slight gravity. The space station's gravity is only 10% less powerful than that of the Earth.

Astronauts can move objects as heavy as hundreds of pounds with their fingertips because they are constantly falling through space, despite the fact that the spacecraft, its crew, and all of its cargo are falling around our planet in a specific orbit rather than falling downward as they would on Earth. Although microgravity is sometimes referred to as zero gravity, they are very different phenomena now, and I will explain why.

As opposed to how it appears in pictures, our star is a huge ball of gas. I can explain that nuclear reactions occurring in its core constantly cause the Sun to burn every second. During this process, hundreds of millions of tonnes of hydrogen are converted into almost as much helium.

As a result, enormous amounts of energy are released as gamma rays, which are then converted into light. As a result, the sun does emit blinding light and incredible heat, but it isn't actually on fire because A spacesuit during a spacewalk won't be as dramatic as it's frequently depicted in movies, but after 15 seconds of being in space without protection, a person will lose consciousness due to a lack of oxygen. Before this happens, the person should breathe out as much air as possible because otherwise, this oxygen will damage their lungs from the inside. Then, without the protection of the spacesuit, which is like a mini spaceship, the pressure inside their body will drop, which will cause them to Black holes is enormously frightening, even though this individual won't burst, so they won't want to stay outside for too long.

Black holes are often referred to as cosmic vacuum cleaners, but in reality, they are more like fly traps because they don't actively seek out objects to consume them; instead, they sit there motionless until a star gets too close. Even so, only celestial objects that cross that border are ripped apart. If the sun were suddenly replaced by a black hole, Earth's orbit wouldn't change at the same time that Earth's temperature would change; instead, there would be differences in both.

The sun's storms would influence our planet, and if the black hole that replaced the sun had the same mass as our star, then by the laws of physics, Earth would have to approach it very closely in order to be sucked into it.

Venus is the hottest planet in our solar system, with temperatures hot enough to melt lead, a high-pressure atmosphere, and extremely strong winds.

Scientists don't know why the winds on that planet are growing stronger over time, but they have discovered something intriguing in its clouds. The winds there are 50 times quicker than the planet's spin.
