We enjoy the positive aura the sun brings. We also love to play on sandy beaches during summer and don't even mind being enveloped by the sun's rays. This special star is a source of warmth, and when the weather changes, a ray of sunlight gladdens the heart. Have you wondered for a second what would happen if the sun suddenly disappeared? What would become of us?
In this video, we take a trip to space to see what will become of us if the sun goes out. Ready? Grab a flight suit, and let's get started!
The sun is at the center of our solar system and is also a star. Everything in the solar system revolves around it. It is about 333,000 times the mass of earth and produces the same amount of energy as 100 billion hydrogen bombs. Like most things in space, the stars have a limited lifespan and would die someday. There is no need to start buying star-death insurance yet because this event would happen about 7 billion years from now. Everyone watching this would be dead by then.
While scientists are doing a good job unearthing the sun's goodness, we cannot fully understand how crucial it is to our existence. Because of its mass, it draws all the other planets towards it, and since the earth moves very fast through space, it keeps them moving around itself. The sun forms when a massive cloud of hydrogen and helium grows so large that it collapses under its own weight. The pressure becomes so high that the heat reaches an unbelievable level with high temperatures that causes hydrogen to lose its electrons. The naked hydrogen atoms then fuse into helium, and the reaction releases sufficient energy to counter the pressure of gravity. The battle between energy from fusion and gravity fuels billions of stars in our galaxy and beyond.
Before you imagine a world where there is no sunlight, let's appreciate its importance to our health. Here are some ways you can benefit from the sun rays:
It reduces the rate of heart disease
According to a British Medical Journal report, UK residents are more likely to die of heart disease in winter than in summer because of lower vitamin D levels. Cholesterol levels are higher in winter because of a shortfall in vitamin D.
Reduces the risk of cancers
Before now, you learned that excessive exposure to the sun increases your chances of skin cancer. While this is true, the sun plays a vital role in preventing other diseases. Sunlight can reduce the risk of different types of cancer. Why do I say so? A study by the US national cancer institute found that people exposed to the sun are less likely to suffer from colon, bladder, womb, esophagus, or breast cancer.
Boosts fertility
The sun reduces melatonin which is known to suppress fertility. Ever wondered why most persons conceive in summer? Yes, you guessed right! Not only does this star make you fertile, but it also increases the duration of the fertility. A recent study in Turkey showed that women who had limited sunlight exposure reached menopause up to nine years earlier. Men also benefit from this star because it boosts testosterone and keeps them ready for baby-making.
If we woke up one morning and realized that the sun had vamoosed, should we be disturbed?
There is no certainty about how everything would pan out, but scientists are convinced that some of the events in this video would happen.
First, none of us would be here in the first place if the sun didn't exist. Scientists studying the origin of life say that our planet's perfect positioning regarding distance from the sun creates the conditions that permit life on earth. What then would happen to life if the sun leaves us suddenly? Light takes eight minutes to reach the earth. It means that after nine minutes, we would find ourselves in complete darkness. If it happens at night, the moon will retire because it doesn't produce light. We only see the moon because of the sunlight's reflection. As the sun and moon go, other celestial bodies like the planets would remain visible for a brief time before vanishing. Electricity would work for as long as the power lasted. Jupiter is only 33 light minutes away, meaning that we'll continue to see this giant planet for more than an hour after the sudden disappearance.
The earth would be a colder place if we didn't have the sun's warmth. It means that millions of people would freeze, and life would be tough. Researchers say that the average global temperature would drop below 0°F within a week. If you live in colder climes, you're probably used to this weather, but how about people in the tropics? They'll likely die off within a few hours.
