Rene Kail said:Why should you prefer the view that cosmological expansion is due to distant galaxies moving apart according to the Hubble Law instead of cosmic space stretching, like stretching of space(-time) in the vicinity of black holes?
Cosmic expansion is the phenomenon in which the space between celestial objects in the universe is continuously increasing. This expansion is believed to be caused by the force of dark energy, which is pushing galaxies further apart.
The Hubble Law, also known as the Hubble Expansion, is a fundamental law of cosmology that describes the relationship between the distance of an object in the universe and its velocity. It states that the farther away an object is, the faster it is moving away from us.
The Hubble Law allows scientists to measure the rate of cosmic expansion and understand the evolution of the universe. It also provides evidence for the Big Bang theory and helps us understand the age, size, and composition of the universe.
The Hubble Law is based on observable data and does not require any assumptions about the nature of space or time. It also allows for more accurate predictions of the expansion rate and can be used to measure distances to faraway objects.
The Hubble Law provides strong evidence for the expansion of the universe by showing that the farther away a galaxy is, the faster it is moving away from us. This supports the idea of an expanding universe and the concept of cosmic expansion.
