New theory explains gravity better than Einstein's relativity:
"When it comes to explaining gravity, Einstein's theories of relativity are the gold
standard. That doesn't mean they're perfect, however. For instance, in order to
account for the large-scale movements of galaxies under Einstein's theories, scientists
have had to postulate the existence of dark matter, a mysterious, undetectable
substance that purportedly must make up as much as 80 percent of all matter in the
universe.
But now there's a new theory on the block that's based on the idea that the universe
is a hologram, and it doesn't require dark matter or its elusive cousin, dark energy, to
explain gravity on a larger scale, reports Phys.org.
The idea, proposed by Erik Verlinde, renowned expert in string theory at the University
of Amsterdam, is that gravity is not a fundamental force of nature, but instead an
emergent phenomenon. This is a subtle but crucial distinction. In the same way,
temperature is also not a fundamental force, but rather a phenomenon that arises
from the movements of particles."
