The mysteries hidden in the Universe have always fascinated scientists and people interested in this area. Recent studies reveal some amazing data. It looks like our world acts similar to an expanding bubble situated in an extra dimension. The findings were published these days in the Physical Review Letters.
Scientists are hoping to use the information for solving the enigma of dark energy. The research is based on the idea that the Universe is actually a bubble dwelling and expanding in an additional dimension.
Here is the full story
The team of researchers from Uppsala University started from a theory known for 20 years – the Universe’s expansion is happening at an accelerating rate. The phenomenon is caused by the so-called “dark energy”, a force that ”spreads” the Universe all over, forcing it to expand. Once we manage to understand what this dark energy really is, we will be able to understand one of the fundamental physics main enigmas.
Although everybody was counting on string theory for providing an answer to this question, it seems that the key might be somewhere else. The string theory claims that every piece of matter is made out of continuously vibrating tiny, “stringlike” entities.
In the article published recently, scientists based their research on a more recent idea. According to this theory, the Universe can be considered a continuously expanding bubble which lies on the edge of another dimension.
The study puts everything we knew so far in a different light. The model provided by Uppsala scientists helps us understand some things about the Universe’s creation and future. More studies are being conducted in this area and researchers are hoping to find answer to more questions. They will share results as soon as they learn more.
