Chameleon Theory Could Change How Scientists Think About Gravity

Researchers found that f(R)-gravity – a so-called Chameleon Theory – could also explain the formation of structures in the cosmos.

  Einstein’s theory of General Relativity is world famous – but it might not be the only way to explain how gravity works and how galaxies form.

  Our researchers found that f(R)-gravity – a so-called Chameleon Theory – could also explain the formation of structures in the cosmos.

  The simulations show that disc spiral galaxies like our Milky Way still form, even when a different law of gravity is applied.

  Scientists already know that f(R)-gravity can reproduce the success of General Relativity in demonstrating the evolution of our solar system.

  But our new research now shows that this theory can also be applied to galaxy formation on very large cosmological scales.

  Instead, it shows that there might be more than one way to explain gravity’s role in the evolution of the universe.

  However, models like f(R)-gravity can also explain the universe’s rapid growth and our researchers say their work could also be small step towards identifying what dark energy is.
