With Marvel and DC expanding their comic book movie universes with upcoming blockbusters like Batman V Superman: Dawn of Justice and Captain America: Civil War, Fox is attempting to hold their own. Their continuation of the X-Men universe, X-Men: Apocalypse, will arrive in 2016 and the reboot of their Fantastic Four franchise opens in less than a week (as of this writing).

Based on the Ultimate Fantastic Four comic book run and distancing itself from the studio’s previous adaptations with a darker tone, director Josh Trank’s reboot faced something of an uphill battle from fans and was cloaked in mystery for a long time. Now, of course, we’ve seen a blitz of marketing over the past months, from trailers to posters to character featurettes, all amid confirmation that a crossover between X-Men and Fantastic Four is in development.

The various – and seemingly endless – TV spots and featurettes for the films have focused on a variety of different aspects of the four – Reed Richards (Miles Teller), Sue Storm (Kate Mara), Johnny Storm (Michael B. Jordan) and Ben Grimm (Jamie Bell) – whose trip to an alternate dimension results in their returning with superpowers. From portraying them as a group of misfits to focusing on the group dynamic, the various PR spots have generally examined the characters from different angles.

Now we have several new featurettes delving into the real-world scientific possibilities of the Fantastic Four’s powers. The first one explores the powers of Sue Storm, A.K.A. the Invisible Woman. Theoretical physicist Dr. Michio Kaku guides viewers through a brief exploration of how the notion of invisibility may no longer be quite as far fetched as previously imagined. Watch the video above.

Next, Dr. Kaku introduces viewers to “quantum entanglements,” and how the study of quantum physics makes the idea of teleportation – which Reed Richards is pursuing when the four gain their powers – part of a new scientific frontier. Watch it below:

One of the core plot devices of this Fantastic Four is the alternate dimension discovered when Reed, Sue, Johnny and Ben take their fateful jaunt in Reed Richards’ invention. Dr. Kaku explains in the video below how the theory of the multiverse hinges on the study of subatomic elements, and specifically how electrons “exist in multiple states until we recognize or study them.” 

Finally, Dr. Kaku touches on the theory of wormholes (a device used in Christopher Nolan’s Interstellar), and how the Large Hadron Collider at CERN (The European Organization for Nuclear Research in Switzerland) seeks to recreate the theoretical conditions resulting in the Big Bang… conditions which may have involved the reaction of matter from the other end of a massive wormhole. Watch it below:

While the existence of wormholes are the one theory featured in these videos which Fantastic Four doesn’t seem to include – as far as we know, anyway – these videos manage to function as effective pieces of marketing and benefit from the presence of Dr. Michio Kaku, a professor of theoretical physics at City College of New York and the bestseller author a various popular science books. Highlighting the real-world scientific possibilities behind the powers of the Fantastic Four is a fun idea, even if these videos end up highlighting the “fiction” in the science-fictional elements of the reboot.

Fantastic Four opens in theaters on August 7, 2015, followed by Deadpool on February 12, 2016; X-Men: Apocalypse on May 27, 2016; Gambit on October 7, 2016; Wolverine on March 3, 2017; Fantastic Four 2 on June 9, 2017; and some as-yet unspecified X-Men film on July 13, 2018.
