The concept of a physical center of the universe is actually a misconception. The universe does not have a center, as it is constantly expanding in all directions. Every point in the universe can be considered the center.
No, the universe is not expanding into anything. It is simply expanding in all directions. The universe does not have a boundary or edge, so there is nothing for it to expand into.
We know the universe is expanding through observations and measurements of the redshift of light from distant galaxies. This redshift indicates that galaxies are moving away from us, and the farther away they are, the faster they are moving. This suggests that the entire universe is expanding.
The rate of expansion of the universe is known as the Hubble constant, and it is currently estimated to be approximately 70 kilometers per second per megaparsec (km/s/Mpc). This means that for every megaparsec (3.26 million light-years) of distance, the universe is expanding at a rate of 70 km/s.
We currently do not know for certain if the universe will continue to expand forever. The expansion of the universe is influenced by dark energy, which is a mysterious force that is causing the expansion to accelerate. Depending on the amount of dark energy in the universe, the expansion may continue forever or eventually slow down and reverse. Ongoing research and observations are helping us better understand the fate of the universe.
