Universe in Breaking the Rules, New Discovery Shakes Shakes Modern Physics | WION

[00:00:00]The universe was supposed to slow down.

[00:00:02]Gravity should have pulled galaxies closer over billions of years, but space is doing exactly the opposite. It is accelerating faster and in more unpredictable manner than scientists imagined. Now, new research and fresh data from some of the world's most powerful telescopes suggest the biggest mystery in modern cosmology may have just become even bigger. Watch our next report for more details.

[00:00:29]>> [snorts] >> For decades, scientists believed they understood the basic story of the cosmos.

[00:00:50]The universe exploded into existence with the Big Bang.

[00:00:56]Galaxies spread apart.

[00:01:00]Gravity slowly pulled against that expansion, [music] simple, predictable, and ordered.

[00:01:10]Then came the shock. In the late 1990s, astronomers discovered something deeply unsettling.

[00:01:16]The universe was not slowing down at all. It was speeding up. Some unknown force was overpowering gravity itself.

[00:01:24]Scientists called it dark energy.

[00:01:27]But here is the problem. Nobody truly knows what dark energy actually is.

[00:01:33]Now, an international team of researchers studying distant galaxies and supernova explosions says the mystery may be even stranger than expected.

[00:01:45]New findings published in Astronomy and Astrophysics suggest the expansion rate of the universe may not behave consistently across cosmic time.

[00:01:58]NASA-backed observations are also sharpening the debate [music] around the so-called Hubble tension. Different methods of measuring the universe produce different answers.

[00:02:09]One says the cosmos [music] is expanding faster than expected, another says slower, and both appear correct.

[00:02:22]That contradiction has become [music] one of the biggest crises in physics.

[00:02:27]Scientists are now questioning whether Einstein's [music] understanding of gravity is incomplete on cosmic scales.

[00:02:34]Others believe an unknown particle or [music] hidden force may exist across the universe.

[00:02:40]Some theories even suggest dark energy itself could be evolving over time.

[00:02:46]If true, the entire fate of the cosmos may need [music] rewriting.
