Indian astrophysicist wins 10-year-old challenge on Dark Matter

India’s renowned theoretical physicist Thanu Padmanabhan has won a ten-year-old challenge on dark energy. The Professor presented his idea on the dark energy to the international community of astrophysicists back in 2006 and asked everyone to prove him wrong by next decade — 2016. It is now confirmed that everyone failed to prove him wrong and he won his own challenge on the dark energy.

The announcement was made by David Wiltshire in the CosPa2016 International conference held in Sydney.

Dark matter is the most mysterious entity in our universe as no one has actually seen or experienced what dark matter is. Scientists believe that more than one-third of our universe is made up of dark matter and it is a hot topic among cosmologists and space enthusiasts.

Padmanabhan presented his idea on the dark matter at the 23rd Texas Symposium on December 15, 2006, and asked the attendants and physicists all around the globe to prove his idea wrong in next ten years.

It was Wiltshire who openly accepted the challenge and said he will prove the theory wrong. Wiltshire is professor in the department of physics and astronomy, University of Canterbury, New Zealand.

Padmanabhan’s theory says that dark energy (cosmological constant) is the root cause of accelerated expansion of the universe and mathematics has proved that dark energy behaves like a fluid which has negative pressure.

However, Wiltshire failed to prove the theory is wrong. In addition, Padmanabhan along with his daughter Hamsa Padmanabhan used Einstein’s theory and determined the numerical value of cosmological constant.

Reportedly, the terms and conditions of this bet were that if Wiltshire won the challenge, he would get a clock (which he could choose). This would ‘help him keep better track of the lack of constancy of cosmological ideas’. Wiltshire conceded defeat last week and sent Padmanabhan money. “He transferred the amount and I bought the lamp last week. At the symposium in Australia, Wiltshire publicly admitted that he was beaten, while showing my photograph with the lamp,” Padmanabhan said.
