Does the Earth move around the Sun forever?

Yes for now. Since everything has a gravitational pull, the earth will always revolve around the sun.

But no, the sun will gradually turn into a black hole near the end of its lifespan (with 5 billion years left) and the earth will be swallowed up.

In addition, the information of the Sun: The Sun is a yellow dwarf, and the lifespan of the yellow dwarf is about 10 billion years, and the Sun is currently about 5 billion years old. In about 5 billion years, the Sun's interior will be almost completely depleted of hydrogen and the Sun's core will collapse, causing the temperature to rise, a process that will continue until the Sun begins to fuse helium into carbon.

Since helium combustion produces more energy than hydrogen combustion, the outer layers of the Sun will expand and release a portion of the outer atmosphere into space. When the process of switching to new fuels ends, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars (at which point the two planets will be farther away from the Sun due to the decrease in the mass of the Sun). Reference.

No, the sun will gradually turn into a black hole near the end of its lifespan, and the earth will be swallowed up.

If not, the Earth would be destroyed by the impact of other objects.

As long as you don't deviate from the first law! Seems like that, right?!

You will do it in this life ... You won't know in the next life... Just like a woman, revolves around you today. Can you promise not to revolve around someone else tomorrow?

The principle of rotation between the stars is the same as when we take a small rope and tie a rubber hoop.

We picked the eraser and gave it an outward centrifugal force.

When the centrifugal force is greater than the pulling force, the rope will break the rubber and fly out in a straight line; When the pulling force is less, the rubber will lose the power to rotate and fall down; When the centrifugal force and the pulling force are equal, the eraser will rotate around our hand and will neither fly out nor fall off.

The same is true of the principle of rotation between stars, gravitational attraction.

It's the invisible rope. Because the pulling force of the sun is the same as the centrifugal force of the earth's rotation, the earth will continue to rotate and will not fly away from the sun, nor will it rush headlong towards the sun.

The earth only rotates because the sun rotates at high speed. The equatorial plane of the solar system space body of the solar system, which is rotated by the gravitational pull of the sun due to the rotation of the sun, does not rotate itself.

The rotation of the earth is due to the fact that the gravity of the earth body has a heavy region and a light region, so that the heavy region presses on the light region and rotates. It's like a ball on an inclined plane rolling down. The difference is that the ball on the inclined plane rolls down and is a condition given by the inclined plane.

The rotation of the earth is the reaction of the sun's light and heat with the water on the surface of the earth and the expansion of the earth into qi and leaving the ground, making the sphere the lightest during the day. At night, the water vapor that expands into gas by the interaction with the sun's light and heat increases the weight of the sphere at night, and the area of the sphere is the heaviest every morning, and the heavy side presses the light side to rotate. It can be seen that the rotation of the earth is not the effect of the gravitational force of the sun, nor is it the effect of inertia, it is not rotation at all, but the movement of energy.
