NASA researchers have found that Earth's gravity is changing all the time, and scientists are warning of consequences in the near future. Many people may not know that a change in gravity of even one percent can be catastrophic. In fact, people tend to underestimate the things they can't see, and gravity is one of them. What happens if we change the quantity a little bit? Reducing it by, say, one percent would have little effect on humans. We will walk, breathe and see each other as normal. However, all sensors on Earth's satellites are prone to errors because they rely on data measured in centimetres, and small differences can cause huge changes.
What if gravity doubled? Some athletes may be shocked to learn that they can no longer lift the bar at the same weight. Some weather stations will notice a slight increase in temperature because the Earth will move closer to the sun as gravity increases. This may not seem like a big deal, and it is, but even small changes in the gravitational field can have serious long-term consequences 39bet-kết quả bóng đá-kết quả xổ số miền bắc-kèo bóng đá -soi cầu bóng đá-đặt cược.
A decrease or increase in gravity must affect the Earth's core and the surrounding mantle. All layers of our planet vibrate at the same time, leading to the destruction of many underground structures that are immediately penetrated by hot magma. Over time, this will lead to a series of volcanic eruptions in different parts of the planet, and that's how scary gravity changes. But why are we so dependent on gravity?
In 1687, Isaac Newton discovered a force called gravity. Even now, scientists are still debating this question. Newton determined that all the objects in the world attract each other, but the magnitude of this force depends on the masses of the objects and the distance between them, and that's what Newton's laws are all about. In the 20th century, however, Albert Einstein realized it was necessary to make some adjustments to the formula.
Newton's assumptions work well here on Earth, but they are clearly not enough to calculate the gravitational fields of objects outside our solar system. This is where Albert Einstein's general theory of relativity came in. For scientists, general relativity is a set of laws that have long been equivalent to the Bible. But that theory, too, now seems to need rethinking, because it can't account for the interactions between gravity and quantum-processes that took place in the first milliseconds after the Big Bang, but gravity's importance is self-evident.
What would happen if gravity increased dramatically? First, many animals will die. The giraffe would not be able to lift its head off the ground, and all the whales would drown. As humans get smaller and shorter in size, the effects of Earth's gravity doubling will be huge. The core of our planet will not be able to withstand this load, it will collapse, the whole Earth will look like a giant doughnut, hot magma will flow out of it. This is the consequence of increased gravity.
What happens when gravity disappears completely? In such a situation, people will see many unusual phenomena. First, each person generates their own gravitational field that attracts various small objects, such as paper clips or pencils, but for larger objects, we become the attracted party instead, stuck helplessly to the bus. After that, people and other everyday objects will begin to fly into space. The biggest source of gravity near a planet is the moon, and many objects will fly all the way there, perhaps at speeds of up to 200 meters per second, and eventually human destruction.
But what would happen if there was no gravity in the entire universe? Perhaps you already know the answer, according to a Dutch theoretical scientist named Eric: "In the gravitational field, our planet will break into pieces and other celestial bodies will suffer the same fate. Eventually, the universe would be a soup of scattered atoms and molecules. So the importance of gravity is obvious, but scientists have found that the Earth's gravity changes very slightly, just like the Earth changes 24 hours a day. Only the amount of change is too small, but in the future, these changes over time may catch humans by surprise, don't you think? Feel free to leave your comments!
