Not that I know of. There are some issues that arise with the simplest model of the Big Bang, but those can be resolved by invoking a physical process that is still consistent with the basic premise of the Big Bang Theory. Specifically, the fact that the CMB temperature is the same ever...

The Big Bang was not an explosion in space, as the theory's name might suggest. Instead, it was the appearance of space everywhere in the universe, researchers have said. According to the Big Bang theory, the universe was born as a very hot, very dense, single point in space. Cosmologi...
This James Webb Space Telescope discovery might blow your mind Stephen Hawking's black hole theory has big implications for the shape of the universe, new study claims Gamma-ray bursts reveal largest structure in the universe is bigger and closer to Earth than we knew: 'The jury is still...
Scientists have not disproved the Big Bang Theory, but they have discovered disagreements in the rate of expansion — the Hubble Constant — from different research teams' measurements. The disagreement is known as the Hubble tension. In short, speed measurements based on telescope observations of...
Update September 17, 2024: The headline from the earth.com website readsStudy: Big Bang theory of the universe is refuted by Webb telescope observations.The discoveries of the James Web Space Telescope (JWST) have all but ended the Big Bang model and standard cosmology that goes with it. ...

Some cosmologists use the big bang theory to estimate the age of the universe. But due to different measurement techniques, not all cosmologists agree on the actual age. In fact, the range spans more than a billion years! The discovery that the universe is expanding led to another question....
