Recent studies have revealed the existence of a mysterious force known as dark energy, which has been credited with driving the accelerating expansion of the universe. Now, a new study has found that this dark energy may have been present in the early universe, up to a billion years after the Big Bang. This finding could help to explain the so-called “Hubble tension”—a discrepancy between two different measurements of the expansion rate of the universe.

A new study has revealed that dark energy might have been present in the early universe, up to a billion years after the Big Bang. This could provide a possible explanation for the mysterious “Hubble tension” - the discrepancy between two different measurements of the universe’s expansion rate. By understanding dark energy’s role in the early universe, researchers are hoping to unlock the secrets of the universe’s accelerating expansion.
