A theoretical proposition Published in the journal Relations on progress in physics makes daring affirmations on our previous understanding of quantum physics. Above all, that we were wrong.
The proposed theory is faced with the fact that quantum mechanics (essentially modern physics) and general relativity (the theory of gravity of Einstein) perfectly describe the universe, but are mathematically incompatible One with each other.
To make them work, the proposal suggests deleting almost everything we think about gravity, as Live science explain. Instead, the authors touch up the theory to correspond to known and observable physics, something they call unified gravity.
Although the theory of the quantum field – the framework explaining how the subatomic particles behave – is one of the most precise theoretical concepts of all time according to Theoretical physicist David TongIt always leaves aside classical gravity, which we know as the bending of space-time.
Instead, the unified gravity assumes that gravity is managed by four connected components that interact perfectly with each other, an adjustment that allows Other dimensions. In short, a model that physicists could really test in real life.
“The main advantages or differences in comparison with many other theories of quantum gravity are that our theory does not need additional dimensions that do not yet have direct experimental support,” said co-author Jukka Tulkki Live science.
The gap between theories of physics and gravity has a long history. To get around, some have proposed that the universe could be made tiny. Others, like the string theorists From the late 1960s and 1970s, pleaded for a one -dimensional framework for particle physics.
String theory Balon in five distinct theories in the 80s, and has since fell under in -depth examination As his supporters find it difficult to make predictions that we can really prove.
“Are you continuing a ghost or is the collection of you too stupid to understand this?” as Neil Degrasse Tyson joked In 2011. This new model is an attempt to jump all this.
In the future, there is a lot of work to do before knowing if the budding theory is bearing fruit.
“Given the current rhythm of theoretical and observation progress, this could take a few decades to make the first experimental breakthroughs which provide us with direct proof of the effects of quantum gravity,” said Mikko Parten, the other author of the study Live science. “Indirect evidence by advanced observations could be obtained earlier.”
However, he offers physicists a new daring path to inflict on a long time to unite quantum physics with the theory of gravity – the possibility of disentangle the tangled secrets of the known universe.
