Forget Dark Energy: Professor Claims ‘Time Big Bangs’ Could Redefine Our Understanding of the Universe

Last year, Professor Richard Lieu made a bold claim: gravity might exist even without mass. This idea challenges traditional physics and seeks to explain dark matter and dark energy—two mysterious forces at the heart of our understanding of the universe. While these concepts are essential to modern cosmology, we’ve yet to definitively detect them, leading some experts to question their existence altogether.

Now, Lieu has taken his ideas a step further. He has proposed the existence of "transient temporal singularities." Imagine tiny, mini Big Bang events that could create bursts of matter and energy before disappearing in an instant.

In a recent statement, Lieu explained how this new model could better account for how the universe forms and expands. He suggests that these singularities could act similarly to dark matter, creating an invisible mass five times greater than all the visible matter we know. They would also exert negative pressure, mimicking the effects of dark energy and pushing the universe to expand even faster.

One intriguing aspect of his proposal is that these singularities emerge and vanish without breaking the laws of conservation. Because they occur infrequently and for a brief moment, they remain undetectable. This might explain why researchers have yet to find dark matter and dark energy, as their presence might be hidden in these fleeting events.

However, Lieu’s ideas face challenges. Some galaxies show signs of having less dark matter than expected, while others seem to have more. This raises questions about the uniformity that Lieu’s model proposes. Additionally, scientists need ways to test these singularities. If they appear and vanish too quickly, can we ever confirm their existence?

This study was published in the journal Classical and Quantum Gravity. The ongoing debate around dark matter and dark energy highlights the scientific community’s willingness to question existing theories. As research continues, these discussions keep pushing the boundaries of what we understand about the universe.
