Is there anything in the universe not in motion?

Everything in the Universe is in motion because forces exist in the Universe. If there were no forces, there would be no motion. The question of why there are forces in the Universe is currently unanswerable by science.

Is matter constant in the universe?

According to the law of conservation of matter the total amount of matter in the universe is constant. It can neither be created or destroyed.

Can something have energy even if it’s not moving?

All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. Potential energy is stored energy. Even when an object is sitting still, it has energy stored inside that can be turned into kinetic energy (motion).

Is it possible for something to be perfectly still?

No. It is impossible for any human to be completely still.

Can you ever be still in space?

Yes, it is possible to be essentially standing still in relationship to the Sun. There are many comments and an answer telling you why you can’t and, as far as they go, they are correct. If you move far enough away from our sun, it become just another star.

Can we create dark energy?

One leading hypothesis is that dark matter consists of exotic particles that don’t interact with normal matter or light but that still exert a gravitational pull. Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab.

Can you have no potential energy?

There are some well-accepted choices of initial potential energy. For example, the lowest height in a problem is usually defined as zero potential energy, or if an object is in space, the farthest point away from the system is often defined as zero potential energy.

Why can’t we keep completely still?

Two reasons, depending how literally you mean “perfectly still”. One reason is that your smooth/cardiac muscle is doing its own thing. You cannot consciously stop your stomach from digesting or your heart from beating, and these cause tiny vibrations in your body. The second is that nothing can be perfectly still.

Is the universe moving away from US?

Take a look out at almost any galaxy in the Universe, and you’ll find it’s moving away from us. The farther away it is, the faster it appears to recede. As light travels through the Universe, it gets shifted to longer and redder wavelengths, as though the fabric of space itself is being stretched.

What would happen if the universe was filled evenly with matter?

If all you had was a Universe filled uniformly and evenly with matter, that matter would simply get less dense and would see everything expand away from everything else as time went on.

What are the characteristics of Einstein’s static universe?

Einstein’s static universe is closed (i.e. has hyperspherical topology and positive spatial curvature), and contains uniform dust and a positive cosmological constant with value precisely , where is Newtonian gravitational constant, is the energy density of the matter in the universe and is the speed of light.

Can the universe ever reach equilibrium?

This is complicated a bit by the fact that the universe is expanding. In an expanding universe you can never really reach equilibrium — but the scientists of the 1800s didn’t know about the expanding universe so let’s just assume that the universe is static.
