Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
The big bang (if it is still a valid theory) would have been unlike any explosion you have ever witnessed. The big bang was not an explosion of only matter, since time and space were both created during this event as well.
Really, calling it an explosion is not right in the first place. It’s one of those unfortunate cases of bad naming in science, another being ‘The God Particle’ (which was originally supposed to be The Goddamn Particle.) Physicists prefer using the word ‘expansion.’
