In the vastness of space, a force is at play,
Dark Energy, the driver of the universe's sway,
It's changing, some scientists say, in a way that's new,
Challenging our understanding of time and space, too.
A discovery of great magnitude, they might be on the cusp,
A rethink of the universe's workings, a fundamental hush,
The current theory, developed by Einstein's great mind,
May be upended, as new evidence starts to unwind.
Prof Ofer Lahav, from University College London's halls,
Says it's a dramatic moment, a paradigm shift that enthralls,
The discovery of Dark Energy, a shock in its own right,
A speeding universe, no slowing in sight.
Galaxies accelerating, a mystery to unravel and share,
Astronomers observing, with data to compare,
The Dark Energy Spectroscopic Instrument, a tool so grand,
5,000 optical fibres, scanning galaxies across the land.
A year ago, a blip in the data, many thought it a mistake,
But now it's grown stronger, a trend that's hard to fake,
Prof Seshadri Nadathur, confident in the results so fine,
A discovery brewing, or just a data
