AlSo said:thanks phinds, that is very useful. I always feel uneasy when I hear scientists say "the farther Universe expands faster"----this seemed to commit the same mistake we made centuries ago----placing the Earth at the centre of the Universe. Cheers!
Universe expansion refers to the theory that the universe is continuously growing and stretching outwards. This means that the distance between galaxies and other celestial bodies is increasing over time.
Scientists have observed a phenomenon called redshift, where the light from distant galaxies appears to be shifted towards the red end of the light spectrum. This indicates that these galaxies are moving away from us, providing evidence for universe expansion.
The exact cause of universe expansion is still unknown and is an ongoing area of research. However, the leading theory is that it is driven by dark energy, a mysterious force that makes up a large portion of the universe's energy and is pushing everything apart.
Based on current observations and theories, it is believed that the universe will continue to expand indefinitely. However, the rate of expansion may change over time depending on the amount of dark energy present.
If the universe continues to expand at an accelerating rate, it is likely that galaxies and other celestial bodies will become increasingly isolated from each other. This could potentially lead to a "heat death" scenario where the universe becomes cold and dark as all energy is spread out and no longer available for use by living beings.
