no it's because space itself is expanding which causes things more distant from each other to be moving away from each other faster, the wikipedia article about hubbles law has a graphic illustrating the priciple with bread https://en.wikipedia.org/wiki/Hubble%27s_law

Wikipedia is not a proper source and I’ve no idea why people stopped considering this and now use it as such. The graphic may be fine, but provide a real source when pushing back against another commenter.

Pages contain other sources, however, which makes WP a good place to begin research on a topic.

This place isn't debate club and nobody's getting a prize for winning an Internet argument.

No they don’t. Wikipedia pages, according to their own rules, contain secondary sources.

To be fair to Wikipedia, it’s come on a long way since its early days when anyone could make whatever edits they wanted. The most popular entries on the site are very well vetted, though not perfect. Just my 2 cents.
