Creation Definition and 323 Threads

Creationism is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation.
In its broadest sense, creationism includes a continuum of religious views, which vary in their acceptance or rejection of scientific explanations such as evolution that describe the origin and development of natural phenomena.The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and that the only true explanations are those which are compatible with a Christian fundamentalist literal interpretation of the creation myths found in the Bible's Genesis creation narrative. Since the 1970s, the most common form of this has been Young Earth creationism which posits special creation of the universe and lifeforms within the last 10,000 years on the basis of flood geology, and promotes pseudoscientific creation science. From the 18th century onward, Old Earth creationism accepted geological time harmonized with Genesis through gap or day-age theory, while supporting anti-evolution. Modern old-Earth creationists support progressive creationism and continue to reject evolutionary explanations. Following political controversy, creation science was reformulated as intelligent design and neo-creationism.Mainline Protestants and the Catholic Church reconcile modern science with their faith in Creation through forms of theistic evolution which hold that God purposefully created through the laws of nature, and accept evolution. Some groups call their belief evolutionary creationism. Less prominently, there are also members of the Islamic and Hindu faiths who are creationists. Use of the term "creationist" in this context dates back to Charles Darwin's unpublished 1842 sketch draft for what became On the Origin of Species, and he used the term later in letters to colleagues. Asa Gray published a 1873 article in The Nation saying a "special creationist" who held that species "were supernaturally originated just as they are, by the very terms of his doctrine places them out of the reach of scientific explanation."

    B What Drives the Accelerating Expansion of Space?

    If space is expanding and at the same time speeding up, something must be driving it. It also appears to be self perpetuating, as something cannot continue to expand, speed up and backfill at the same time? Could the driving force be dark matter/energy?

    When a particle and antiparticle pair is created are they created on the same position? If they weren't in the same position it would lead a problem on energy conservation, but they are fermions so they shouldn't be on the same position in space.

    Reheating vs particle creation due to acceleration

    It seems during cosmic inflation the universe expands at an accelerated rate. This expansion is driven by the potential of the inflaton field.
