Fakta

The concept of cosmic expansion is foundational to modern cosmology. It describes the way the universe has been stretching out over time, with galaxies moving away from each other. This phenomenon was first observed in the early 20th century by astronomer Edwin Hubble, who discovered that distant galaxies were receding from the Earth. The further a galaxy was, the faster it seemed to move away. This led to the realization that the universe itself was expanding, not just galaxies moving within a static space. The discovery was groundbreaking because it suggested that the universe had a beginning—a moment when all matter and energy were concentrated in a singular point. This insight laid the groundwork for the Big Bang theory, which proposes that the universe began from an incredibly hot and dense state and has been expanding ever since.

Before this discovery, the prevailing belief in astronomy was that the universe was static, neither expanding nor contracting. However, Hubble’s findings, supported by the work of other scientists like Alexander Friedmann and Georges Lemaître, showed that space itself was expanding. This meant that the fabric of the universe was stretching, causing galaxies to drift apart over time. Understanding cosmic expansion was pivotal not only in explaining the universe’s origins but also in forming the basis for further study of its evolution and ultimate fate.

At first, scientists believed that the expansion of the universe would eventually slow down due to gravitational pull. This expectation, however, changed with the discovery of dark energy in the late 20th century. Observations of distant supernovae revealed that not only was the universe expanding, but this expansion was actually accelerating. This unexpected acceleration is attributed to dark energy, a mysterious force that permeates space and drives galaxies apart at an ever-increasing rate.
