Another thing that could happen would be that a black hole would be formed. Once again, the gravity would make the sun implode on itself, but the gravity would stay as the dominant force, forming a black hole.

Black Holes Explained – From Birth to Death

# data[].attributes.body
During a supernova explosion, the sun implodes on itself, and gravity takes over. The black hole would disassemble everything into it's elementary particles. Black holes slowly radiate their mass off, but this process is extremely slow. It would take a black hole with the mass of our sun 10,000 billion billion billion billion billion billion years to lose 0.0000001% of it's mass. In destroying everything, it could destroy Information itself.

Why Black Holes Could Delete The Universe - The Information Paradox

Black holes are scary things. But they also might reveal the true nature of the universe to us. This video was funded by SNSF under Agora Grant n. 171622 and through the NCCR SwissMAP: The Mathematics of Physics.

Information is typically understood as the arrangement of particles. Imagine a bunch of carbon atoms. Arrange them in a certain way, and you get coal. Arrange them in a different way and you get a diamond. The basic building blocks for everything in the universe is made up out of carbon atoms. The atoms don't exactly care whether they are part of an apple, a car, or a coffee cup. Information is what makes everything unique in the universe. But black holes destroy information. They take everything, and make it the same.

Compared with the billions of other stars in the universe, the sun is unremarkable. But for Earth and the other planets that revolve around it, the sun is a powerful center of attention. It holds the solar system together; pours life-giving light, heat, and energy on Earth; and generates space weather.

Characteristics of the Sun

The sun is a big star. At about 864,000 miles (1.4 million kilometers) wide, it could hold 109 planet Earths across its surface. If the sun were a hollow ball, more than a million Earths could stuff inside it. But the sun isn't hollow; it's filled with scorching hot gases that account for more than 99.8 percent of the total mass in the solar system. The temperature is about 10,000 degrees Fahrenheit (5,500 degrees Celsius) on the surface and more than 28 million degrees Fahrenheit (15.5 million Celsius) at the core.

Deep in the sun's core, nuclear fusion reactions convert hydrogen to helium, which generates energy. Particles of light called photons carry this energy through the sun's spherical shell, called the radiative zone, to the top layer of the solar interior, the convection zone. There, boiling motions of gases (like in a lava lamp) transfer the energy to the surface. This journey takes more than a million years.

The sun's surface, or atmosphere, is divided into three regions: the photosphere, the chromosphere, and the solar corona. The photosphere is the visible surface of the sun and the lowest layer of the atmosphere. Just above the photosphere are the chromosphere and the corona, which also emit visible light but are only seen during a solar eclipse, when the moon passes between the Earth and sun.

Solar Wind and Flares

In addition to light, the sun radiates heat and a steady stream of charged particles known as the solar wind. The wind blows about 280 miles (450 kilometers) persecond throughout the solar system. Every so often, a patch of particles will burst from the sun in a solar flare, which can disrupt satellite communications and knock out power on Earth. Flares usually stem from the activity of sunspots, cool regions of the photosphere related to a shifting magnetic field inside the sun.

Like many energy sources, the sun is not forever. It is already about 4.5 billion years old and has used up nearly half of the hydrogen in its core. The sun will continue to burn through the hydrogen for another five billion years or so, and then helium will become its primary fuel. The sun will expand to about a hundred times its current size, swallowing Earth and other planets. It will burn as a red giant for another billion years and then collapse into a white dwarf about the size of planet Earth.

Even if the sun explodes, and destroys half of the solar system, we may just have killed ourselves off by then. About 40 years ago, we had planet-destroying weapons pointed at each other, and we aren't too far from history repeating itself. If this keeps happening, we could either kill ourselves off, or, if technological progress doubles, we may be in another solar system by then.

Gravity traps us here on Earth. In order to escape it, in a nutshell, we need to travel almost sideways to escape Earth. Earth is a ball, right? At some point , you would break the plane of gravity. Then, you are out in Earth's orbit. Things with mass attract other things with mass. The larger mass pulls on the smaller mass, forcing it into it's ring of orbit.

Imagine a empty room, and you need to fill it with laundry. Put as many baskets of laundry as you can in the room. At some point, the room will be completely full, not a single sock more can fit in. But, in theory, you could force the sock in the room, with a lot of pressure and speed. But, the room would end up collapsing in on itself, forming a black hole.

The sun would end up rapidly expanding as a white dwarf star, until the gravitational force pulling on the sun on the inside would implode on itself, burning every planet from Mercury to Mars, including us.
