What is the last year on Earth?

Answer 1

Our sun is about halfway through its life cycle. It will be a few more billion years before it becomes a red giant that will engulf the earth and kill all life on it. Then after that it will explode into a super nova and scatter all the remaining planets into interstellar dust. Our sun, called, Sol, originated from several other stars that lived out their lives and exploded into cosmic debri. After millions of years this debri condensed and formed our solar system with the sun at the center and the planets revolving around it. Unless we find a way to transport ourselves, including all aspects of nature with us to another star, all life on earth will be extinguished, forever.

Answer 2

The earth will die in roughly one billion years when the moon goes too far away. However, this might not happen. The most probable answer is that in five billion years the Earth will have been engulfed by the Sun.

Answer 3

Depends if you mean the planet Earth or life on the planet.

In about 5 billion years when the Sun turns into a red giant, the Earth will become so hot that its crust will melt. There is some debate as to whether the Sun's envelope will extend sufficiently to "boil" away the surface of the Earth, but the chances of any life surviving will be zero.

If the envelope extends sufficiently, the Earth will basically evaporate into space and will be no longer.

It all probability, based on current knowledge, the Earth as a planet will survive when the Sun dies, and will become nothing more than a cold rock orbiting a cooling white dwarf for the rest of the universes existence.
We can only speculate.

Answer 4

It is not scientifically possible to predict when the Earth will come to an end. The planet has been around for billions of years and will continue to exist for many more, barring any catastrophic events.

Answer 5

The Sun grows 10% hotter and 10% brighter every 1 billion years. In about 1 billion years from now the Earth will be too hot to sustain any surface water as a result, life will not be able to sustain itself on Earth. Assuming we have not destroyed ourselves by then.

The Earth is not alive. Accepted science states that at some far distant future point (millions of years from now), the sun will expand into a red giant, and engulf the Earth.

The Earth itself will hopefully not be destroyed until the Sun's lifespan comes to an end, in about 5 billion years, working on the knowledge that the Sun is 4.5 billion years old, and is middle aged.

Answer 6

The Sun is one of the lower-mass stars. It passes through main sequence which it is currently in, giant star where it expands, and white dwarf. The stage where it will be impossible for life to exist on earth is the giant star. The Sun will heat up and expand. Helium will fuse into carbon, too. But don't worry, it will take about 5 billion years to be impossible for life to exist.

Answer 7

If you study the lifeline of other stars like our sun, you will find that there is a stage called a red giant. During this stage, the Sun will grow to 250 times its current size. Well before it reaches that state, the surface of the sun will have advanced much closer to us, the oceans will boil away, and earth's rocks will become molten. How long till all this happens? Somewhere in the vicinity of 1.5 billion years from now. The sun will go on for some time after that, though - about 4.5 billion years before the sun takes it's final bow. Earth will be a distant memory by then.

Answer 8

We will never know when the planet will "die." Some people believe that the world will end based on religious teachings, some believe it will end because of the human impact, etc. We will probably never truly know when the world will end and the planet will 'die.'

Answer 9

If anyone knew the answer to that question ...

-- don't you think everyone would have heard about it by now ?

-- do you think the person who knew it would decide to tell anyone else, or not to ?

Answer 10

Nothing. The Earth is fine, regardless of the "Chicken Littles" who proclaim that the sky is falling. The Earth frequently goes through periods of unsettled weather for a few hundred years, and we didn't cause it last time, and we didn't cause it THIS time.

Remember that out of the last million years, 900,000 of them have been ice ages. During that entire time, there wasn't enough civilization to invent writing, so we have no records of it. We look at the last 50 years of pleasant weather and think that this is what it ALWAYS is - but the only constant is change! We DON'T WANT the ice to come back, but at some point it will.
