Why is the universe expanding.
That said, I'm not convinced it's saying the universe is "expanding" the way science sees it. But the chapter involves The Holy Spirit. IMO, that breath inhales and exhales (to an infinite degree), so you might say it contracts and "expands." I think "heavens" (shamayim) is another way of saying "The Holy Spirit," so stretch[ing] "like a ...
By precisely determining the expansion rate, called the Hubble constant, the cosmic clock can be rewound and the age of the universe calculated. However, Edwin Hubble's estimates of the expansion implied that the universe was younger than the age of the Earth and the Sun. Hubble, therefore, concluded that the redshift phenomenon was an unknown ... The expanding universe is finite in both time and space. The reason that the universe did not collapse, as Newton's and Einstein's equations said it might, is that it had been expanding from the moment of its creation. The universe is in a constant state of change. The expanding universe, a new idea based on modern physics, laid to rest the ...The expansion or contraction of the universe depends on its content and past history.

There are numerous laws that govern the universe, such as the laws of mechanics, thermodynamics...
Dark energy is a repulsive force and makes up roughly 68% of energy in the known universe. Scientists believe that the existence of dark energy and the amount of repulsion it displays compared with dark matter is what's causing our universe to not only expand, but also to expand faster and faster. Hubble …

Black Holes. Overview The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown. If the distance ladder group is in error, and the expansion rate is truly on the low end and near 67 km/s/Mpc, the Universe could fall into line. But if the cosmic microwave background group is ...Here's the short answer: That question doesn't make sense. The universe is everything, so it isn't expanding into anything. It's just expanding.

The Expanding Universe. Perhaps the most astonishing and revolutionary discovery in cosmology was Edwin Hubble's observation that galaxies are moving away from us. It provides the underpinning of the big bang picture of creation in which the universe is expanding, and has been for 13.7 billion years. But astronomers in the last century were ...
The Hubble constant is named after the astronomer Edwin P. Hubble, who astonished the world in the 1920s by confirming our universe has been expanding since it exploded into being 13.7 billion years ago. In the late 1990s, astronomers discovered the expansion is accelerating, or speeding up, over time.Feb 3, 2015 · Credit: Wikimedia, T.Reyes.
