Introduction: A Journey Through Space-Time

If we could speak the language of the cosmos, it would undoubtedly echo the voice of Professor Stephen Hawking. Notably, the year 2013 has been one of his most influential periods. This particular time in Hawking’s career was marked by exceptional breakthroughs in theoretical physics and cosmology. Guiding us through a journey across the universe, Hawking’s insights provide fascinating perspectives on everything from black holes to the origins of existence.

Chapter 1: Unveiling the Truth About Black Holes

In 2013, Stephen Hawking presented a controversial and thought-provoking idea about black holes. Contrary to the prevailing belief, he asserted that black holes do not possess event horizons. This daring insight, known as the Hawking Radiation Paradox, deeply influenced the astronomical community.

Hawking’s Radiation Paradox: The Breakthrough of 2013

Hawking proposed that black holes are surrounded by "apparent horizons" instead of the previously accepted event horizons. These apparent horizons merely hold matter and energy temporarily before releasing them back into the cosmos, unlike their predecessors which were deemed inescapable. Hawking’s assertion of information paradox-resolution created waves in the scientific community, revolutionizing our understanding of black holes.

Chapter 2: The "No Boundary" Hypothesis

Another groundbreaking theory proposed by Hawking in 2013 is the "No Boundary" hypothesis. This theory, which he developed with James Hartle, suggests that the universe did not have a temporal beginning.

The Universe’s Very Beginnings

By eradicating the existence of a "boundary" or a starting point to time, Hawking opened the door to postulate a new perspective on the nature of the universe. His "No Boundary" hypothesis implies that the universe is self-contained and does not require an external force to determine its current state. This hypothesis gives rise to a fascinating question: if the universe has no boundaries, what lies beyond it?

Chapter 3: The Mystery of Dark Matter

While not as overtly groundbreaking as the first two, Hawking’s input on dark matter offers an intriguing standpoint. He suggested that primordial black holes might contribute to the elusive dark matter that composes approximately 27% of the universe.

Primordial Black Holes and Dark Matter: A Profound Connection

Primordial black holes, unlike the stellar black holes arising from star collapse, originated shortly after the Big Bang. Hawking’s revolutionary idea implies that these primordial black holes might have a correlation to dark matter. Despite dark matter’s enigmatic nature, Hawking’s 2013 outlook gives us a deeper understanding and offers an explanation for this existential puzzle.

Conclusion: The Enduring Legacy of Stephen Hawking

Through his innovative ideas and enduring dedication to physics and cosmology, Stephen Hawking has drastically amplified our understanding of the universe. His intensive work in 2013 remains a testament to his monumental contributions to various aspects of science.

Hawking’s revolutionary revelations – the Hawking Radiation Paradox, the "No Boundary" hypothesis, and his views on dark matter – continue to inspire and guide scientific thought. His insights, posed in 2013, have reframed our understanding of the universe and forged a path to the new frontiers of cosmology and theoretical physics.
