How is the universe expanding if energy Cannot be created?

It turns out that in Einstein’s theory of general relativity, regions of space with positive energy actually push space outward. So even the expansion of the universe is controlled by the law of energy conservation.

Can the universe be constantly expanding Why How?

Even if the overall spatial extent is infinite and thus the universe cannot get any “larger”, we still say that space is expanding because, locally, the characteristic distance between objects is increasing. As an infinite space grows, it remains infinite.

Is matter being created as the universe expands?

Yes, space is constantly being created. The new space does not hold any matter (like atoms) or dark matter. This means that the density of normal and dark matter decreases at the same rate as the volume increases.

What happens when the universe expands?

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.

Why matter Cannot be created or destroyed in today’s universe?

It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.

What happens to the universe as it expands?

As this wave of impact expands, the Space field fuses with the Time and joins the universe. Otherwise, the energy density of the Universe would have to drop very quickly on average. Matter can be created an destroyed, for example in annihilation, where photons are created.

Does an expanding universe negate the biblical story of creation?

An expanding universe does not negate the biblical story of creation. The great majority of scientists would say that matter is not eternal—that matter did not exist prior to the Big Bang. In fact, the prevailing theory is that nothing at all existed prior to the Big Bang, including time and space.

Will the universe expand to Eternity?

However, current research indicates that the universe may expand to eternity. But research continues and new studies of supernovae in remote galaxies and a force called dark energy may modify the possible fates of the universe.

How did the universe begin?

Scientists have no explanation for how the universe began if neither time nor space nor matter existed prior to the Big Bang. But Christians know that God created everything and that He created the universe ex nihilo (out of nothing). The Creator, existing before the moment of creation, must be immaterial and beyond time and space.
