New evidence shows that ‘Cosmic Acceleration’ and ‘Dark Energy’ don’t exist

Science & Technology

E.SHARMA,

LONDON, Simply, We know that our Universe’s expansion is speeding up? But what if the proof they used to come up with this conclusion was wrongly explained. And now supposed Cosmic Acceleration is simply an artifact. In the big conclusion, there’s no speeding up. So that there also not the mysterious Dark Energy, thought to be creating that Acceleration.

Three scientists Saul Perlmutter, Brian Schmidt, and Adam Riess who won The Nobel Prize for the Cosmic Acceleration idea for the discovery of the accelerating expansion of the Universe through observations of distant supernovae. They used that evidence from exploded stars calledstandard candles’ to show that the Universe’s expansion was getting faster. 

Therefore, Such types of supernovas are so bright that we actually know their exact brightness. This key point allows scientists to estimate the distance of these explosions from our Earth. In the year of 1998, A group of scientists led by Perlmutter and Schmidt found light from 50 supernovas to be dimmer than it was supposed to be, leading that scientist to conclude that cosmic expansion was actually speeding up.

But while the expansion has become accepted as a scientific fact, there has been someone who sees things differently. A new evidence by Oxford University scientist Subir Sarkar and his colleagues’ challenges how were conclusions about cosmic acceleration and Dark Energy were made up of? 

Sarkar thinks, ‘If you look at supernovae, in only a small part of the sky, it would look like you had cosmic acceleration, ‘But we are saying that it is just a simple effect, that we are Non-Copernican observers. It has nothing to do with the dynamics of our whole universe so that nothing to do with Dark Energy’.

Sarkar argued, ‘But here now no one would be arguing with a Nobel Prize-Winner’s conclusions, Someone who believes that ‘The CMB does not directly measure Dark Energy.

According to Mathematical Models, Dark Matter makes up three-quarters of all the matter in the Universe. But it’s never seen or completely explained. Now, An Oxford scientist claims a Nobel-Prize-winning conclusion is wrong and says it has found new evidence that perhaps Dark Matter doesn’t really exist.

KEY POINTS...

1] Paper by Oxford University Physicist Subir Sarkar and his colleagues’ challenges how conclusions about Cosmic Acceleration and dark energy were reached.

2] Physicists who proved Cosmic Acceleration shared a Nobel Prize.

3] Subir Sarkar did use statistical analysis to question the key data for that, but his methodology also has some detractors.
