- 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
- 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
- Hermitian operator lt;= gt; observable? - Physics Forums
'Observable' is simply a name; it means that there is an hermitean operator with real eigenvalues which can in principle correspond to results of measurements If you don't like this wording then you may call it 'hermitean operator' in order to make clear that a constructive approach for the measureemnt itself is missing Killtech said:
- The Universe vs Observable Universe • Physics Forums
The discussion clarifies the distinction between the observable universe and the entire universe, emphasizing that the observable universe is limited by the speed of light and the finite age of the universe The Big Bang, which occurred 13 8 billion years ago, did not originate from a single point in space, but rather, the universe has been expanding ever since, potentially being infinite from
- 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
- How does the observable Universe have meaning? • Physics Forums
The observable universe refers to the portion of the universe that can be seen from a specific location, such as Earth, and is defined by a radius of approximately 13 8 billion light years Observers in different locations, like other planets, would have their own observable universes, which may include regions beyond what is observable from Earth The concept raises questions about the
- Comparable size of the observable universe immediately after inflation
Regarding scale How big was the region of the universe we now understand to be the observable universe, immediately after early inflation? I'm tyring to understand the scale I know our sphere of observation is very approximately 45 billion light years or something, I don't know for sure
- What is the projection postulate in quantum mechanics?
Hi, I really need help solving this problem, can you pleasez help me with it? Here is the problem: An operator A, representing observable A, has two normalized eigenstates w1 and w2, with eigenvalues a1 and a2, respectively Operator B, representing observable B, has two normalized
