WebWe have shown that there is a simple relation between conformal relativity (Hoyle–Narlikar theory) and a reduced (graviton-dilaton) low-energy-effective superstring theory to Brans–Dicke theory. This relation shows that the former is recovered from Brans–Dicke theory if one takes ω = −3/2 while the latter is recovered if one takes ω ...

What is the physical significance of the dilaton in string theory?

WebJun 15, 2024 · Researchers have sought the quantum theory of gravity since the 1930s. They’ve found candidate ideas — notably string theory, which says gravity and all other phenomena arise from minuscule vibrating strings — but so far these possibilities remain conjectural and incompletely understood. WebYes. The 'bottom up' approach has worked in the past for particle physics. But strings are most certainly top-down in philosophy. mandragara • 5 yr. ago. I guess it depends on what you mean by top-down. To me top down means: empirical observations -> quantitative variables -> predictive theory. rantonels • 5 yr. ago. climate change ar6

Science Simplified: Loop Quantum Gravity vs. String Theory

WebAnswer: Remember no natural field without boson carries its force, so graviton is gravitational field boson, but it is very weak interacting particle, so its detection is still not … WebJan 20, 2024 · String theory is a framework that physicists use to describe how forces usually conceptualized on a gigantic level, like gravity, could affect tiny objects like electrons and protons. WebString theory, even in the low-energy limit, demands a much greater degree of symmetry than even this, which means that a low-energy prediction of superpartners should arise. … boat sonar depth finder
