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 Use of the term "creationist" in this context dates back to Charles Darwin's unpublished 1842 sketch draft for what became On the Origin of Species, and he used the term later in letters to colleagues.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."
How was matter created in this universe?
If the Higgs Boson is theoretically able to create matter from energy, then isn't that fairly good proof that it exists?
Or are there other explanations?

Okay, I've heard that in Stephen Hawking's new book, The Grand Design, he claims that the law gravity somehow created the universe from nothing. Can any of you give me a conceptual understanding of how this could occur?
This has puzzled me for a very long time. I know the theory that the universe was created from a big bang, but this means that all the matter in the universe existed in a different form before that. Be it gas or some other weird substance, it still existed. So how can all this substance appear...
Greetings,
I see the same questions asked repeatedly (including by myself). It would be great if once a question is answered, it be added to a FAQ. A FAQ for each forum category.
Such questions include:
1) Does an object A moving relative to an object B exert a stronger gravitational...
I know people get tired of answering questions about photons, but I have a question regarding the best way to think of how light (i.e. E-M waves) are created.

But my understanding of...
Hello, I have a conundrum I cannot fathom a reasonable explanation to.

Hello,

I found in one book that the energy required for creation of one photoelectron in silicon

But when the energy is...

What is the analog of particle creation and vacuum energy in the Bohmian approach? Has Bohmian QFT been developed to a point where it can provide a satisfactory explanation of this phenomenon within it's framework?
So the Hamiltonian of the wave-function of the universe is equivalent to zero. Am I correct in interpreting this as a statement that, if taken together, all the energies of the universe, in some sense, would "sum to zero"? If energy cannot be created, nor destroyed, then the fact that they "sum...
