The question of what existed before the Big Bang is one of the most profound and challenging in cosmology. It’s important to understand that our current understanding of physics breaks down at the point of the Big Bang singularity, so any answers are necessarily speculative. However, scientists are exploring various theories. Here’s a breakdown of some key concepts:

• The Initial Singularity:
• The traditional Big Bang model posits an initial singularity, a point of infinite density and temperature. In this model, “before” the Big Bang has no meaning, as time and space themselves originated with the Big Bang.
• Cosmic Inflation:
• The theory of cosmic inflation proposes that the universe underwent a period of extremely rapid expansion in the moments following the Big Bang. Some theories suggest that inflation could have been triggered by events that occurred before the Big Bang.
• “Bouncing” Cosmologies:
• Some models propose a “bouncing” universe, where our Big Bang was not the beginning, but rather a transition from a previous contracting universe. In these models, the universe “bounces” from a contraction phase to an expansion phase. Recent research, including studies involving primordial black holes and dark matter, explore these “bouncing” cosmology models.
• Multiverse Theories:
• Other theories suggest that our universe is just one of many in a multiverse. In this view, the Big Bang could have been the result of a collision or interaction between universes.
  Key points to remember:
• The “before” is a very hard concept to grasp, as time itself is theorized to have started with the big bang.
• Scientific research is ongoing, and new theories are constantly being developed.
• The study of primordial black holes and dark matter may provide key insights into this area of cosmology.
  It’s a very exciting time for cosmology, as scientists continue to push the boundaries of our understanding of the universe.

In the 1930s, researchers first noticed oddities in how galaxies moved, suggesting something invisible exerted gravitational pull.( the dark matter theory)

Dark matter has baffled physicists for nearly a century, quietly shaping our universe’s unseen framework. Invisible yet influential, it provides the gravity necessary to hold galaxies together, driving their motion and structure.

About 85% of all matter in the universe stays hidden, undetectable even with today’s best technology. Remarkably, scientists suspect this mysterious material may have existed even before the Big Bang.

In the 1930s, researchers first noticed oddities in how galaxies moved, suggesting something invisible exerted gravitational pull. Decades later, studies of the cosmic microwave background—the lingering radiation from the universe’s birth—confirmed dark matter’s importance in shaping cosmic evolution.

A pivotal study by the Planck Collaboration in 2018 revealed that dark matter makes up roughly 27% of the universe’s total energy. By comparison, ordinary matter—the stuff of planets, stars, and us—accounts for only 5%.

Scientists have spent decades trying to understand what dark matter might be. Supersymmetry, a popular theory in particle physics, proposes a “partner” particle for every known particle, potentially offering clues about dark matter’s identity.

From this theory, weakly interacting massive particles, or WIMPs, have become leading candidates for dark matter. These hypothetical particles barely interact with ordinary matter, yet experiments underground and at particle accelerators could possibly detect them

One such groundbreaking idea is the “Dark Big Bang” (DBB) theory, proposed in 2023 by Katherine Freese and Martin Winkler from the University of Texas at Austin. Unlike the conventional Big Bang, which explains the birth of ordinary matter, the DBB suggests that dark matter arose from a separate event. 

This second Big Bang, occurring sometime after the first, would have generated dark matter through the decay of a quantum field trapped in a false vacuum state.

In this model, the early universe consisted of two sectors: the visible sector, filled with the familiar particles and forces, and a dark sector, which remained cold and decoupled. Eventually, the dark sector underwent its own phase transition, analogous to the visible sector’s hot Big Bang.
