00:00Imagine a time when there was nothing.
00:05No space, no time, no matter.
00:07That's how our universe began.
00:09It all started with a tiny point, smaller than an atom,
00:12filled with unimaginable energy.
00:14Then, 13.8 billion years ago, it happened.
00:17The Big Bang.
00:18The point exploded, expanding faster than the speed of light.
00:21Space itself was created in that instant.
00:24As the universe expanded, it cooled.
00:26Energy transformed into particles,
00:28forming the building blocks of everything we see today.
00:31The Big Bang was the birth of our universe,
00:33a cosmic explosion that set everything in motion.
00:36From this primordial soup,
00:38the universe began its incredible journey of evolution.
00:44After the Big Bang, the universe was a chaotic sea of particles,
00:48but gravity, the force that pulls things together,
00:51started to sculpt order from the chaos.
00:53Over millions of years, gravity drew particles together,
00:56forming giant clouds of gas and dust.
00:59These clouds, called nebulae, became the birthplaces of stars.
01:02As gravity pulled the gas and dust closer,
01:05the pressure and temperature at the centre increased dramatically.
01:08Finally, it got so hot that hydrogen atoms fused together,
01:13releasing enormous amounts of energy.
01:15The first stars were born.
01:16These early stars were massive and short-lived.
01:19They burned brightly, producing heavier elements,
01:23like carbon, oxygen and iron in their cores.
01:26When these stars exploded as supernovae,
01:29they scattered these elements throughout space.
01:34While stars were forming,
01:35gravity continued to shape the universe on a grander scale.
01:38vast clouds of hydrogen and helium,
01:41enriched with the remnants of dead stars,
01:43were pulled together by gravity's relentless tug.
01:46These immense collections of stars, gas, dust and dark matter
01:49became the galaxies, islands of light in the vast cosmic ocean.
01:53Our own galaxy, the Milky Way,
01:55is just one of billions upon billions of galaxies in the observable universe.
01:59galaxies come in a variety of shapes and sizes,
02:02spiral, elliptical, irregular,
02:04each a testament to the intricate dance of gravity
02:07and the evolution of the cosmos.
02:12About 4.6 billion years ago,
02:14in a quiet corner of the Milky Way,
02:16a new chapter in the cosmic story was about to unfold.
02:19In the swirling disk of gas and dust surrounding a young star,
02:23our sun, a planet began to form.
02:26Dust grains, remnants of long dead stars,
02:29clumped together, drawn by electrostatic forces.
02:32As these clumps grew larger,
02:34their gravity increased,
02:35pulling in more and more material.
02:37Over millions of years,
02:38this process, called accretion, formed planetesimals,
02:41the building blocks of planets.
02:43One of these planetesimals,
02:45destined to become our Earth,
02:47continued to grow,
02:48sweeping up debris in its orbital path.
02:51Collisions with other planetesimals
02:53released enormous amounts of heat,
02:55keeping the early Earth in a molten state.
