Gravity is a fundamental force of nature, which means it exists everywhere in the universe. It is the invisible pull that objects have on one another. Sir Isaac Newton was the first to mathematically describe this force, explaining not only why an apple falls from a tree, but also why the Moon stays near the Earth.

The strength of gravity depends on two things: mass and distance. Mass is the amount of matter, or 'stuff', in an object. The more mass an object has, the stronger its gravitational pull. This is why the Sun, the most massive object in our solar system, has the strongest gravity.

The Sun's immense gravity is the reason we have a solar system. This gravitational attraction is what keeps all the planets, including our Earth, from flying away into space. Without this constant pull, the planets would simply drift off in a straight line into the cosmos.

However, gravity does not act alone. Planets also have their own forward motion from when the solar system formed. To stay in orbit, planets must (21) __________ a perfect balance between this forward speed and the Sun's inward pull. (22) __________ creates the stable, curved path called an orbit. Little (23) __________ we realize this same principle keeps us on the ground.

(24) __________, gravity is the invisible director of the solar system's beautiful dance. It is the cosmic glue that holds everything together, from the smallest moon to the largest star. It organizes the universe and creates the stable system that allows life to exist on Earth.

The human spirit’s capacity to overcome immense challenges resonates globally, with countless inspiring tales of individuals rising from humble beginnings to extraordinary success. These "rags-to-riches" narratives underscore determination, hard work, and unwavering vision. In Vietnam, a shining example is Nguyễn Thị Phương Thảo. Her journey, from a student selling goods on the streets to becoming the CEO of VietJet Air and Vietnam's first self-made female billionaire, shows what is possible when one dares to dream big. Her remarkable rise is a powerful reminder that humble origins are no barrier to achieving greatness.

Born into modest circumstances, Phương Thảo's early life showed an innate entrepreneurial drive. While studying in Eastern Europe, she began ventures in the late 1980s.

This practical experience laid a crucial foundation, teaching her resilience and resourcefulness from a young age, preparing her for the much larger challenges and opportunities that lay ahead in her career.

Returning to Vietnam, Phương Thảo expanded her business empire, investing in finance, banking, and real estate. Her most transformative move came next. Recognizing Vietnam's burgeoning aviation market, she envisioned a low-cost airline, making air travel accessible. This bold idea led to VietJet Air's establishment in 2007. Despite initial skepticism and significant hurdles, her conviction remained unshaken. She meticulously built the airline, focusing on efficiency, customer experience, and an innovative business model that challenged existing norms.

[I] Under her leadership, VietJet Air rapidly expanded routes and fleet, becoming a dominant player in both domestic and international skies. [II] Its vibrant branding and affordable fares quickly captured a large market share, transforming the way Vietnamese people travel. [III] Her achievements are frequently highlighted in Vietnamese business circles, serving as a powerful narrative of homegrown success built on grit and foresight. [IV]

Nguyễn Thị Phương Thảo's story is more than a business case; it's an inspiring saga about resilience and limitless potential. For young people, especially aged 14-15, her journey offers a vital lesson: your starting point in life does not dictate your ultimate destination. Whether facing challenges or setbacks, her example demonstrates that with unwavering ambition, smart decision-making, and courage to pursue unconventional paths, one can truly redefine their future and achieve audacious dreams, proving that true success stems from within.
