According to a recent newspaper report, an international team of astronomers studying nearly $446000$ galaxies via the Hubble Space Telescope has confirmed that the expansion of the universe is accelerating. By utilising a technique known as "weak gravitational lensing" to observe how light is distorted by dark matter, researchers mapped the distribution of matter and the history of cosmic expansion, determining that an unknown force called "dark energy" has been driving this acceleration for the past two billion years. This study, which involved $1000$ hours of observation and $600$ Earth orbits by the Hubble telescope, marks the first time such measurements were successfully conducted using gravitational lensing alone, and it further reinforces the existence of an invisible web of dark matter that constitutes $80%$ of the universe.
