Thanks to Dr Oliver Tattersal, an expert on modified gravity theories for helping me with the content of this video: https://www2.physics.ox.ac.uk/contacts/people/tattersall

Here are the review papers that he sent my way to get me started for those who want a deep dive (note: written for the academic community - you may prefer to read Pedro Ferreira's book 'The Perfect Theory' which is written for a public audience: https://www.amazon.co.uk/dp/B00CTMAAN4/ref=dp-kindle-redirect?_encoding=UTF8&btkr=1)
Ferreira (2019) - https://arxiv.org/pdf/1902.10503.pdf
Berti et al. (2015) - https://arxiv.org/pdf/1501.07274.pdf
Clifton et al. (2012) - https://arxiv.org/pdf/1106.2476.pdf

And BONUS - a fairly recent review on String Theory from Mukhi (2011) - https://arxiv.org/pdf/1110.2569.pdf
