Things That Appear Unchanged Despite the Passage of Time

It is a common human experience to see familiar faces and places and feel that despite the passing of time, certain things remain unchanged. From the height of an average human to the seemingly eternal silhouette of a mountain, numerous elements of our world persist through the ages, yet they are subject to constant underlying changes. Let's explore some of these enduring and seemingly unchanging elements.

The Average Height of a Human Being

One aspect that has undergone significant changes over time is the average height of humans. This shift is particularly fascinating when viewed through the lens of global comparison. Historically, the average human height in Europe showed a dramatic decline. During the Middle Ages, the average height was approximately 68.27 inches. However, this height dropped to a low of 65.75 inches in the 1600s and 1700s. It was not until the 18th century and onwards that heights began to increase again. Such changes highlight the impact of nutritional and health conditions on physical development over time.

A Mountain Stays the Same Despite the Passage of Time

An enduring image that persists is the mountain. Surprisingly, despite the changing climate, vegetation growth, and even the presence of wildlife, a mountain retains its nearly unchanged appearance from year to year. Mountains are formed over millions of years through the process of erosion, volcanic activity, or tectonic shifts, and they remain remarkably stable compared to human lifespans. However, changes do occur – from the growth of plants to the alteration of landscape through rainfall – which gradually reshape the mountain's surface.

The Night Sky: A Constant and a Vast Change

The night sky, too, appears to be a constant. However, upon closer examination, it reveals a profound and continuous change – not a physical one, but a relative one. Stars are continually moving away from the Earth, and in the distant future, no stars will be visible to us. Moreover, the Moon is slowly drifting away from the Earth, and some scientists estimate that in about 5 billion years, both the Earth and the Moon will be swallowed by the Sun. These changes, though happening at a vastly slow rate, are irreversible and transformative.

The Evolution of Language

Language is another example of something that appears constant but is in fact undergoing constant change. If you were to travel back in time 3-400 years, you would find that the language you speak today would be barely recognizable. This is especially true for English, which has undergone numerous transformations in the last few centuries. Language evolves not just in spelling and pronunciation but in syntax and vocabulary as well. Even the way we communicate in the present day differs significantly from how it was used even a few decades ago.

Perception of Time and Our Reliance on Now

Finally, our perception of time is a fascinating aspect of human nature. We are incredibly efficient in managing and remembering the now, but we often fail to capture the continuous cycle of this present moment. The now is always defined as we are in the midst of it, but as we move forward, it becomes a recollection of the past – then. This transition from then to now to the next now happens seamlessly, and we rarely stop to reflect on how much we have changed over time. This is not just about physical changes but also about mental and emotional growth.

To conclude, while there are things that appear to remain unchanged, such as the average height of a human, the stability of a mountain, the beauty of a night sky, the constancy of language, and the fleeting nature of the present moment, the reality is that everything is constantly changing. It is this change that defines our world and shapes our understanding of time.
