Does space move? What is space?
Can't we just say that the objects are moving away from each other, through space, and the space itself is not moving?phinds said:It "expands" in the sense that things get farther apart.
For objects far away, this is not consistent with observations.k9b4 said:Can't we just say that the objects are moving away from each other, through space, and the space itself is not moving?
But hang on, what do you mean it's not consistent with observations? How can you observe space moving? You can only observe relative motion, as dalespam pointed out in my other thread in this subforum.mfb said:For objects far away, this is not consistent with observations.
In the same way the hypothesis "there is no sun" is not consistent, just with more math involved.k9b4 said:But hang on, what do you mean it's not consistent with observations?
Right, but there is no model that can reproduce the observed redshifts with objects moving in space.How can you observe space moving? You can only observe relative motion, as dalespam pointed out in my other thread in this subforum.
This is a common question and the answer is not straightforward. Space itself does not move in a traditional sense, as it is not a physical object that can be displaced. However, the objects within space, such as planets, stars, and galaxies, are constantly in motion due to the forces of gravity and other factors.
Space is often described as the three-dimensional area in which all matter and energy exist. It is also referred to as the universe, which encompasses all of the known and unknown objects, including planets, stars, galaxies, and other celestial bodies.
The current scientific consensus is that the observable universe is infinite, but this does not necessarily mean that space itself is infinite. It is still a topic of debate and research in the scientific community.
Space is measured in units of distance, such as meters, kilometers, light-years, and astronomical units. These units are used to describe the vast distances between objects in space.
Yes, space can expand. This is known as the theory of the expanding universe, which suggests that the universe is constantly growing and stretching. This expansion is thought to be caused by dark energy, a mysterious force that counteracts the effects of gravity.
