The owner of Nobel Physics talks about the universe

Discovering the expanding universe at a growing speed helps the three scientists win the 2011 Nobel Prize in Physics. Their observations show that after the Big Bang, the universe is constantly expanding and cooling down. .

Telegraph said Dr. Adam Reiss, one of the three winners of the $ 1.5 million prize, talked about his research after the Royal Swedish Academy of Sciences announced Nobel Prize winners. yesterday. He used the image of a raisin sandwich in an oven to illustrate the expansion of the universe. Each grape represents a galaxy. The earth is in a grape.

'If you sit inside a raisin, you will see raisins moving away. That's because the universe is expanding. What happens next is a difficult question. Previously we predicted the rate of expansion of the bread, which is the universe, will decrease until the expansion process stops. Then in 1998 we found that the rate of expansion of the universe did not decrease, but also increased over time. The universe is getting bigger , "Reiss said.

No one has found the reason for the universe to expand with increasing speed, but the discovery of three scientists makes the scientific community more interested in the theory of 'dark matter' - which can occupy up to three parts. private universe. Currently the scientific community is trying to find evidence of the existence of dark matter with the European Atomic Research Organization's large particle accelerator.
