- Radius of the Observable Universe in Light-years Is Greater than Its Age
The radius of the observable universe is about 46 billion light-years, which is considerably greater than its age of about 14 billion years The radius of the observable universe is defined by the greatest distance from which light would have had time to reach us since the Big Bang, so you might think that it would lie at a distance of only 14 billion light-years, since x=ct for motion at a
- Is the Universe Finite, or Is It Infinite? - Physics Forums
The observable universe refers to the portion of the universe that we can see or detect, limited by the finite time light has traveled since the Big Bang It has a finite volume
- Learn Observables in Mathematical Quantum Field Theory
The following is one chapter in a series on Mathematical Quantum Field Theory The previous chapter is 6 Symmetries The next chapter is 8 Phase space 7 Observables In this chapter we discuss these topics: General observables Polynomial off-shell observables and Distributions Polynomial on-shell observables and Distributional solutions to PDEs Local observables and Transgression
- Diameter of the observable Universe • Physics Forums
The observable universe has a diameter of 93 billion light years, but this does not imply that the universe itself has a center; rather, the center is relative to the observer Cosmologists discuss two geometric possibilities for the universe: an infinite flat or negatively curved geometry, which suggests an edge but no center, and a positively curved spherical geometry, which also lacks a
- Intro to the Big Bang and Infinity Concepts - Physics Forums
In the cosmology section of the Physics Forums, I encountered many Big Bang and related infinity problems Hence, in this article, I want to explain the Big Bang, the topology of the Universe, and the concepts of singularities and infinities First, let’s start with the concept of the observable universe and what we mean by that The observable universe is the part of the Universe that we
- States and observables in quantum mechanics • Physics Forums
The discussion focuses on the differences between classical and quantum mechanics regarding the specification of experimental conditions and the determination of system states In classical mechanics, measurable quantities are uniquely defined by coordinates and momenta, while in quantum mechanics, repeated measurements yield probability distributions rather than definitive values The
- Can We See an Atom? Latest Images of Atoms | Physics Forums
Can we see an atom? In this article, I will discuss how these images are made, what exactly we are looking at, and what it really means to see an atom
