How our solar system will end its existence?

Above the artist's impression, what the nova eruption might look like, and the sun will lose its shine in this kind of explosion. In this eruption, about half of the matter of the star will fly to space, and then the result of this kind of eruption is the white dwarf. The white dwarf is not producing its energy in the internal fusion, but it will be extremely hot until its temperature decreases.

When the white dwarf pulls the hydrogen on it, that gas makes the layer, where happens the powerful eruptions. How stable those eruptions are depended on the temperature and the mass of the white dwarf. But if the conditions are right the gravity with the temperature of the white dwarf causes the "type II" nova eruption, where the fusion happens on the surface of that white dwarf. And some futurologists have introduced the idea that civilizations can use the energy of white dwarfs simple way. They can just shoot the dust to the surface of the massive white dwarfs, and collect the energy of that impacts.

There has been introduced a scenario that the asteroid impact to water moon like Europa can push that moon out its trajectory. When the asteroid hits the water moon, it makes a giant crater, where the water can blow to the sky. That water acts like a rocket engine and pushes the moon to journey through the solar system.

About 5 billion years ago the sun will blow as nova and loses half of its mass. Before that, the inner planets Mercury, Venus, Earth, and probably Mars have vanished or vaporized. When the Sun will blow its outer layers away, it will push the remaining planets away, and that means that planets like Jupiter and Saturn can push away from the solar system.

And before that, some water-moons like Europa could vaporize. The reason why the predictions, what happens during the nova eruption is difficult is that when the shockwave hits the gas planet that causes that their atmosphere will overheat on the other side.

That means the vapor acts like some kind of rocket engine, and give the push for the planet, but is that punch so powerful, that it can move the gas giant like Jupiter. The red giant stage of the sun can also push the gas giants farther because that star is heated another side of gas planets and especially Jupiter, which can move away from the sun.

But the fact is that the interaction between objects in the solar system is much more complicated than the simple model, that the planets are orbiting the Sun. Gas giants like Jupiter have also a great effect on the solar system, but the other objects are not meanless. The fact is that if the small object, which has minimal interaction interacts with some particle for billions of years, that effect can turn very big.

Things like the Kuiper Belt and Asteroid belt also have a very big effect on the trajectories of the other particles. Because of the big groups of objects are forming entirety, where the common gravity effect can be very big, and affect the other particles.

But as we know that the white dwarf is not forever. The cosmic radiation will destroy it sooner or later. And at that point, the existence of the solar system ends someday.
