Context:
A new study using fresh supernova data has confirmed that the universe is still expanding at an accelerating rate. This supports the idea that dark energy continues to drive cosmic expansion, despite earlier doubts about the strength of evidence.
Explanation:
- The Big Bang theory explains that the universe began from an extremely hot and dense state and has been expanding ever since.
- In 1998, scientists discovered that the universe’s expansion is not slowing down but accelerating, based on observations of distant Type Ia supernovae.
- Type Ia supernovae act as “standard candles” because their known brightness helps measure cosmic distances.
- The acceleration is mainly linked to dark energy, a mysterious force believed to make up nearly 68% of the universe.
- Dark matter adds gravitational pull, while dark energy pushes expansion outward.
- The study used improved calibration of supernova data, reducing doubts about earlier findings
