Chinese Physicist Demonstrates the Impossibility of Time Travel to the Past, Yet Identifies Two Theoretical Time Loop Scenarios

Insights from Hongshen Zhang's Research

According to Radiotrek — Світ: In 2026, Chinese physicist Hongshen Zhang conducted a mathematical analysis revealing that, according to most cosmological models, traveling back in time is not feasible. His study centers on an equation describing the behavior of light, highlighting a specific mathematical quantity that continuously increases during motion and cannot revert to its original value. This finding leads Zhang to conclude that an object cannot return to a previously occurred event.

Exploring Hypothetical Time Loop Possibilities

Despite these limitations, Zhang proposes two theoretical scenarios where time loops might still be possible:

• The first involves extreme distortions of spacetime near rapidly spinning supermassive objects, such as black holes.
• The second considers a closed universe structure that could, in theory, enable unusual temporal movements.

Whether these conditions actually exist in our universe remains uncertain.

"This is connected to the unique properties of spacetime: a certain mathematical value steadily increases during motion and cannot return to its initial state," Zhang explained.

While Zhang's research does not definitively close the debate on backward time travel, it opens new avenues for understanding the fundamental nature of time and space.

The implications of this work are far-reaching for physics and cosmology, as the question of traveling into the past remains one of the most captivating challenges in science. It encourages ongoing investigation and discussion within the scientific community and may influence the development of advanced theories aiming to unravel the fabric of time and space in greater detail.

While Zhang's findings challenge the notion of backward time travel, they also pave the way for intriguing discussions about the nature of time itself. For those interested in the exceptions that might allow for such phenomena, further insights can be found in a similar article that explores the impossibility of time travel, highlighting notable exceptions proposed by physicist Hongsheng Zhang.
