The Secrets of the Universe: From the Big Bang to Dark Matter

Imagine everything—galaxies, stars, planets, even time itself—compressed into a single point.

That’s how the universe began, in an event called the Big Bang.

About 13.8 billion years ago, this tiny singularity exploded, expanding rapidly and creating the building blocks of everything

we know.

But what triggered it?

Scientists still don’t know.

The laws of physics break down at that moment.

What came before?

That’s one of the greatest mysteries of all.

After the Big Bang, the universe was a hot, dense soup of particles.

As it expanded, things cooled, and atoms formed.

Gravity pulled matter together, creating the first stars and galaxies.

But here’s the twist—most of the universe isn’t made of the matter we see.

Scientists discovered that something invisible, called dark matter, holds galaxies together.

Without it, they’d fly apart.

But what is dark matter?

No one knows yet.

Dark matter is one of the biggest puzzles in physics.

We can’t see it, touch it, or interact with it directly.

But we know it’s there because of its gravitational effects.

Galaxies spin faster than they should, as if held together by an unseen force.

Scientists think dark matter makes up about 85% of the universe’s mass.

But what is it made of?

Exotic particles?

Something beyond our understanding?

The search continues.

If dark matter is strange, dark energy is even weirder.

While dark matter holds galaxies together, dark energy pushes the universe apart.

It’s the force behind the universe’s accelerating expansion.

But what is it?

A new fundamental force?

A property of space itself?

Scientists have no clear answer.

What we do know is that dark energy makes up nearly 70% of the universe.

That means most of reality is something we don’t understand.

The universe is full of mysteries, and we’ve only scratched the surface.

From the Big Bang to dark matter and dark energy, there’s so much we don’t know.

Are there parallel universes?

What happens inside a black hole?

Could we ever travel through time?

Every discovery leads to more questions.

The more we learn, the more we realize how little we understand.

But that’s the beauty of science—endless curiosity.
