Is it possible for mankind to discover how big the universe is?

The observable universe is approximately 93 billion light-years in diameter. This is limited by the distance light has travelled since the Big Bang.
 

The discovery of the universe's expansion was first made by Edwin Hubble in 1929, and it's now known that this expansion is accelerating due to dark energy.
 

CMB radiation, discovered in 1965, provides a snapshot of the universe when it was just 380,000 years old, helping scientists estimate its size and age.
 

Hubble’s Law describes how galaxies are moving away from us and allows scientists to estimate the rate of expansion, which helps in determining the size and age of the universe.
 

About 95% of the universe is composed of dark matter and dark energy, which are still not fully understood. These components affect the universe’s expansion and overall structure.
 

a multiverse, where our universe is just one of many. While not universally accepted or proven, this concept expands the idea of "size" beyond our observable limits.
 

While we can estimate the size of the observable universe and understand its expansion, discovering the exact size of the entire universe remains uncertain.
 

Exploring the entire universe is an impossibility for the mankind due to its vastness and the limits of understanding.
