While summer summer and the temperature rises to the Northern Hemisphere, it is impossible to forget what the day’s life impacts. It is more likely to be a source of all our light and heat, provides enough to keep the tricky climate balance we enjoy. That is not a coincidence; World’s life has evolved under the influence of the day and, given time, adapts of any changes.
Adapting the whims of a star is not a small task, however. The sun can be seen regularly each day, but give time in millions or even valuable years, and things that have changed – a many. And it’s not always for better.
For example, in thermonuclear-driven core, The Sun Fuses About 700 million tons of hydrogen in 695 million tons of helium per second. Lost five million tons of energy converted (by favorite equation of all, e = MC2). It’s enough energy, it’s done, of power is a star. If you want thinking numbers, the sun makes 4 x 1026 Watts of Power-400 trillion trillion watts. That is, the energy that our star exists in a second is enough to satisfy The general consumption of man For 650,000 years.

It’s enough to get our planet warm at the moment Comfy Clime. In fact, by using some basic principles of physics, it is possible to calculate math how hot land should be given at the energy release rate of the day. That solar energy flows in the space in all directions around the sun, and a small part (about half billion) it has been deated on our planet. How much it heals a little complicated, depending on the actual radiant flux from the sun, away from the ground, and more. Numbers run, usually on land judge Temperature is now approximately -15 degrees Celsius, cold than freezing point of water.
ACTUAL The dimensions of ground temperature, however, Give an average hotterAbout 15 degrees C. The difference exists because the gas greenhouse gases are important to heat the heat from the sun, heating ground on the surface of the temperature. This heating usually comes from natural gas gas, think, but We have added approximately 40 billion tons of carbon dioxide atmosphere each yearthat extends the impact of heating. Note that this increase occurred in the past century or so, one-time short to see any change from the sun; The current climate change in the world is all of us.
But making energy in the sun changes changed – in hundreds of millions of years. That the helium made in the core is inexact; Think of it as “ash” from nuclear mix. It has set up the center of the day, which reinforces the time (at the rate of 695 million tonnes per second!). As it gets mass, it also wins the great weight of the layers of the day above it, so it compresses. A basic physics law is that healing a gas healing it, so even the rate of fusion usually, the core of the sun gently warms the time – which means that the sun is growing too much.
If we run the clock ahead an eon or two, we find danger. As the sun shines brighter, it will raise the ground temperature especially We will lose all water vapor around us And then, eventually,, All water above the planet. Our oceans will evaporate. This Global Desiccation is relatively steady planting a stop sign for all life in the world. However, if you have relief, that doesn’t happen until three billion years from now.
The reactions that occur in the core of the day are very complete after this pointBut the biggest impact is that our star’s energy output is finally increased. All energy falls into outer layers of the sun. If you warm up a gas, it expands, so the sun explodes in many proportions – 100 to 150 times wide now. At the same time the temperature over it falls, so it ruddier, even as it shines with energy 2,400 times stronger than it is now. It changed the day of a red giant star.
The sun can be very big, indeed, it Drink Mercury and Venus. WORLD can escape this fate;; Astronomers argoms when the growing day comes to the world or not. As it stands, Things don’t look good.
Even if the land live, it is not beautiful. Our planet’s temperature is about 1,300 degrees c, hot enough to melt lead. In the sun, the stones above melt, and the earth will become a worldly lava. On top of that, our planet will lose the atmosphere to get it hot.
Is there a way for the land to avoid this fate? How are other planets on fares?
To answer the questions honestly and in order they are asked: “not at all“And” bad. “There’s a little bit again because the sun wins, The Solar Air It becomes more powerful – so much, in fact, that the sun has lost a large amount of mass. This means that the gravity of our star is weakening and the planets migrate outside, far from the central blow to the solar solar system.
But it’s not enough. Jupiter, now has a temperature of a chilly -110 degree c, warm up to more than 300 degrees C. In these months to melt and start cooking. We couldn’t find there sanctuary there.
If you want to find even a marginally clement clemement anywhere in the future solar solar system, you can look forward to the pluto, which, with that about 50 times more distant from the sun than the ground today. Its surface temperature will be roughly -10 degrees C. That’s still chilly, but remember the greenhouse effect: there is a lot of frozen methane and carbon dioxide on pluto, so these ices can vaporize to make the tiny world at least somewhat comfortable, if not Exactly habitable.
What’s up? It gets worseIf you can imagine. The sun blows out its outer layers and the core exposed to space, changing the so-called astronomers a white dwarf. While hotter heat, the core is just about the size of the ground, it is very small that gives little heat to the planets. They cool again, eventually falls below the icy point of any biologically beneficial molecule.
If there is any Modicum of the Good News here, this is all it doesn’t happen for many billions of years. Who knows how much man looks like or when we go around? If we, well, many more stars are born all the time, and they have planets, too. Wrapping and moving is not fun, but if your house is on fire, There is no many options. We may find other lands there where we can settle for an eon or three before the whole process begins.
