The big bang has causality issues, particularly the "horizon problem." I critique suggested solutions like cosmic inflation and negentropy, arguing that they require unproven concepts. The Creator, as described in the Bible, provides a coherent explanation without causality violations, in contrast with those scientific storytelling fairy tales for adults.
When we look out into space, even with the most powerful telescopes, are we seeing the universe in real time? Are we observing events as they happen, that is, at the time measured on our local clocks?
Due to medical conditions, my postings on Bible Science Forum will be greatly reduced. I need to limit screen time to prevent blurry eyesight. I apologize for the fewer, and briefer posts.
The exploration of time measurement emphasizes the Earth's rotation as a historical clock, defining the 24-hour day. The development of mechanical clocks, notably John Harrison's marine chronometers, advanced navigation. Time's definition evolved from an Earth-centric model to atomic standards, although fundamental concepts of time remain abstract and intrinsic to the universe's creation.
Day 4 of creation, God made the Sun, Moon, planets, and stars, establishing them as luminaries in the heavens. The language of the Bible uses an Earth-observer perspective, meaning that light from celestial bodies was instantly visible. Additionally, I confront naturalistic explanations for celestial origins, proposing a creationist model.
Mathematicians from University College London and the University of California, Davis, have published a mathematical proof that the Universeβs accelerating expansion can be explained without dark energy, dealing a serious blow to the Lambda-cold dark matter model.
Kinematics: The Velocity-Time Function Authorβs Preface: A Collaborative Approach to Lesson Development The intention behind what I hope will be a series of articles on Kinematics (this one being the first) is to begin an open, collaborative process of lesson development on Physics Forums. In order to expedite this workflow, I am making deliberate use...
Direct answer: Cosmologists classify the universe as open, flat, or closed based on spatial curvature. Current cosmic microwave background (CMB) measurements indicate the universe is very close to flat, but small curvature remains observationally allowed. Whether the universe is ultimately finite or infinite cannot be settled by theory alone, since all three curvature types are...
