Dark Energy

Why do astronomers believe dark matter exits even though they have not seen it?

The Sun orbits at 230km per second despite being 26,700 light-years away from our galaxy’s centre.

New model of the universe could end dark energy mystery once and for all

The model highlights dark energy, which permeates throughout the universe and pushes it to expand.

New 'dark fluid' theory could explain why 95 percent of the universe is 'missing'

Dark fluid explains some mysteries of the universe, like why galaxies don't fly apart as they spin.

Researchers say that our universe is less lumpy than earlier estimates

Dark matter interacts gravitationally with ordinary matter in the universe forming lumps such as stars.

Elusive decay of Higgs Boson to tiny quarks observed by physicists at long last

The Higgs particle's elusive decay to quarks has now been documented by the particle accelerator

Dark matter and dark energy may not actually exist, claims new study by University of Geneva researcher

According to a researcher at the University of Geneva (UNIGE) in Switzerland, these concepts may be no longer valid: the phenomena they are supposed to describe can be demonstrated without them.

LIGO and Virgo gravitational wave detectors can also be used to unlock the secrets of dark matter

Calculations show that certain types of dark matter could form giant clouds around astrophysical black holes.

Indian physicist Thanu Padmanabhan wins decade-long bet on dark energy

Theoretical physicist and IUCAA professor Thanu Padmanabhan has won the decade long challenge he posed to the international community of astrophysicists to prove his ideas on dark energy wrong by 2016.

The Big Bang never happened, suggests a new theory

The Big Bang never happened and our universe may have no beginning and no end, suggests a new theory by physicists, including one of Indian-origin.

Higgs Boson may help explain mysterious attributes of dark energy

One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value, researchers said.
