Think of the Sun: hot, big, and why all of this (cruel form) is possible. Our local constellation influences all living things as we know them, providing energy that supports everything from tiny particles that make up photosynthesizing to the largest animals on land and in the oceans.
But one day, far in the future – the sun will die. Things will not just be dark, though. Instead, they will go very, very bright. Hot, too, unbearable. The sun will be invisible, if anyone is near to see it.
“One of the most important questions that any intelligent person ever has is: how did we get here, what is the point, what does it mean? Questions about our origin and our future, ”said Jackie Faherty, astronomer at the American Museum of Natural History, by telephone. “If you want to understand where our Sun can live, you need to know how long it will last, how it changes, and how it changes. It all comes down to this important issue.”
Which brings us to today’s question: How much of our life-giving day is left, and how do we know?
“Once you realize it’s a gas ball, you know it’s not a limitless machine,” Faherty said. “You need to know when it will end.” Calculating that time is a simple process, built on complex mathematics and small recognition.

To find out how much time the Sun has left – and, the destroyer, is about 5 billion years old – you need to know how many years it is. The stars do not die suddenly, so knowing the age of the stars is a very important sign of the order of the day. In the 19th century, in the course of a debate on the age of the earth, Charles Darwin and Lord Kelvin, astronomer, argued about the age of the Sun. Darwin’s comparisons could have been close; Nuclear power had not yet been found, and Kelvin worked to suppose that the sun was burning coals. It lost its number a bit.
Our solar system is based on the oldest extraterrestrial rocks that move across the solar system, which is basically a rejectament that was not designed to be a planet or a moon at the time of planetary integration. These fossils always give us 4.6 billion years, and scientists can say that they are very accurate. number of channels.
