Quantum physics and general relativity are two key concepts in our understanding of the cosmos. They are among the most brilliant concepts ever devised by the human race, but they refuse to collaborate.
The two
ideas' boundaries are constantly being investigated. Scientists are hoping to
discover hints about the next major theory, which will bridge the gap between quantum
mechanics and relativity. String theory is the most publicized and
controversial concept, although others are being investigated as well.
Researchers
have developed a quantum gravity theory that looks to be successful in
explaining what we observe in the universe today, as well as events requiring
both quantum mechanics and relativity, such as black holes. "Finite
Quantum Gravity Amplitudes: No Strings Attached" is the title of the paper
published in Physical Review Letters.
For the
researchers, one of the most important aspects of the idea is that it is based
on previously tested notions. There is no proof that the string theory-proposed
strings exist. We'd need particle accelerators far more powerful than the
CERN's Large Hadron Collider (LHC) to find them. Quantum gravity theories do
not require strings to behave like particles; they simply assume that particles
exist.
"This alternative theory appeals to scientists since connecting string theory to tests has proven to be extraordinarily difficult. Our concept is based on physical principles that have been proven in the lab. To put it another way, no one has ever seen strings in experiments, while particles are clearly seen during LHC experiments. In a release, co-author professor Frank Saueressig of Radboud University in the Netherlands said, "This allows us to bridge the gap between theoretical predictions and experiments more easily."
The work
lays a solid framework for this idea, but it's the creation of predictions
about the cosmos that's key. A theory can be beautiful and explain all we see,
but it must also be able to anticipate and explain what we will see in the
future.
The
researchers will now try to comprehend the consequences of their new
theoretical framework for black holes by applying it to those cosmic puzzles.
"After all, there is only one set of laws of nature," Saueressig continued, "and this set should be able to apply to all kinds of situations, including what happens when particles clash at extremely high energies or when particles fall into a black hole." "It would be amazing to show that there is a link between these seemingly unrelated questions that permits us to answer the riddles that emerge on both sides."
