Will this solve the mystery of the expansion of the universe?
Physicists’ new proposal that a new type of extra dark energy is involved is highlighted in scientific journal.
The universe was created by a giant bang; the Big Bang 13.8 billion years ago, and then it started to expand. The expansion is ongoing: it is still being stretched out in all directions like a balloon being inflated.
Physicists agree on this much, but something is wrong. Measuring the expansion rate of the universe in different ways leads to different results.
So, is something wrong with the methods of measurement? Or is something going on in the universe that physicists have not yet discovered and therefore have not taken into account?
