There Is No Accelerating Expansion of the Universe

Scientists are trying to prove the accelerating expansion of the universe.

STATES CHRONICLE – During the 1990s, there has been circulating a theory which argued the accelerating expansion of the universe. Nowadays, a new team of scientists from the Department of Physics of Oxford University is thinking about analyzing that theory again. The first theory was formulated when the Hubble Telescope had investigated the thermonuclear eruptions of dying stars. Hubble used dark energy, a substance which drives the expansion to reach an accelerated rhythm. Dark energy was disposed into the limelight.

Now, the scientific team led by Professor Subir Sarkar is questioning the old idea. After Hubble managed to examine more than seven hundred Type la supernovae, the experts have argued that the accelerating expansion of the universe is a theory which does not lie on palpable evidence. The Oxford team’s study was published in Scientific Reports magazine.

Sukar claimed that the proof which could have attested the accelerated expansion was worth it three sigmas. Physicists know that for valuable information to become revolutionary, it takes five sigmas. Sarkar has further added that there is no evidence either for the cosmic microwave background which is assumed to stimulate the accelerated pace of the universe.

Researchers argue that the data about the rhythm of the universe’s expansion only proved to have a constant rate. Sarkar asserted that another framework that supports the idea that the universe is not a homogeneous mass of stars and planets and that its matter content does not react like an optimal gas can explain the theory without considering dark energy. Vacuum energy is a very vague notion that does not lie on basic ideas.

The accelerating expansion of the universe is backed up by another idea such as microwave background which was registered by Planck satellite. Professor Sakar stated that there appears to be an effect of the dark energy existing in cosmos, but it has not been attested. The subtle effect is the Sachs-Wolfe one which displayed late integration.

The theory which Sarkar and his team are trying to present is that physicists are aware of the fact that an important cornerstone of the regular cosmological model is questionable, without bringing evidence to the light. To find some valuable and grounded data, scientists will need to wait for the European Extremely Large Telescope to make its calculations with the help of “laser comb.” This tool is bound to measure over a 15-year time span whether the accelerating expansion is indeed real.
