Navigating parallel universes is ‘for the comic books': Physicist
(NewsNation) — Theoretical physicist Michio Kaku supports the concept of parallel universes, but he says people shouldn't get their hopes up about meeting their doppelganger in another dimension, like Marvel superheroes sometimes do.
Kaku joined 'NewsNation Prime' to discuss various topics, including the possibility of life after death in the wake of Pope Francis' death. He said science can offer only so much insight.
'The amount of energy, the amount of sophistication to go between universes, is far beyond anything we can muster,' Kaku said. 'Marvel Comics got it partially right that, yes, we believe there are parallel universes. But going between them is for the comic books.'
Kaku works in the field of 'String Theory,' which, simply put, suggests reality is comprised of vibrating strings instead of point-like particles. It includes the idea there are more dimensions than humans can perceive, although maybe not an infinite number.

Sound familiar? The concept of multiple realities has been a consistent theme in the Marvel cinematic universe, with characters like Spider-Man and Doctor Strange meeting their variants from other universes.
'Do we believe in parallel universes? Yes,' Kaku said. 'That's called quantum mechanics. That is the foundation of modern society, in fact. But can we go between parallel universes? Well, that's the $64,000 question.'
In theory, he said, there could be 'copies' of people acting independently of one another in different universes. Kaku sees a bright side to this.
'Just because you've messed up in this universe, that doesn't mean you've messed up in all the other universes that you can visit,' he said.

Scarlett Johansson reflects on past 'challenges' of dating non-actors
Scarlett Johansson has reflected on some of the "challenges" she experienced when dating men who worked outside of Hollywood in the past. In a conversation with David Harbour for Interview magazine published on Tuesday, the Marvel movie co-stars discussed how they found it difficult to maintain relationships with "normal people" when they were younger. In particular, Scarlett recalled how some of her previous partners became "jealous" as a result of the "intimate" connections formed between actors on film sets. "I also think it's easy to create a lot of jealousy when a person is not involved in the industry, because actors by nature are very free-spirited and they create very intimate relationships with people at work," she said. "They can be loyal to a partner and also very engaged in all these other kinds of relationships, and I think it can be a blurry line for some people. Also, to have a relationship with the public can be a complicated thing for people outside of the industry to understand." Scarlett has been married three times. She was wed to Ryan Reynolds from 2008 until 2011 and to Romain Dauriac from 2014 until 2017, with whom she shares a 10-year-old daughter named Rose. The Lost in Translation actress also has a three-year-old son, Cosmo, with current husband Colin Jost. Elsewhere in the conversation, Scarlett noted that she prefers to be on her own when she is preparing to shoot a film. "When I'm working, and you're probably like this too, I'm pretty hermetic. If I'm in a town, I like to go to the little restaurant and movie theatre, but I don't like a lot of variation. I like things to be, I don't want to say rigorous, but you want a routine," the 40-year-old added. Most recently, Scarlett has been promoting her directorial debut, Eleanor the Great.

‘The Fantastic Four' Director Matt Shakman Reveals the ‘Magical' Comics That Inspired the Film in ‘Small and Large Ways' (EXCLUSIVE)
Before Iron Man, before the Hulk, before Spider-Man, there was the Fantastic Four. The quartet of astronauts transformed into superheroes were Stan Lee and Jack Kirby's first creation for Marvel Comics, launching the sprawling storytelling universe of interconnected characters that has endured for 64 years. Until Disney acquired 20th Century Fox in 2019, however, Reed Richards (a.k.a. Mr. Fantastic), Sue Storm (a.k.a. the Invisible Woman), Johnny Storm (a.k.a. the Human Torch) and Ben Grimm (a.k.a. the Thing), as were unable to join the Marvel Cinematic Universe. That will finally change in July with the premiere of Marvel Studios' 'The Fantastic Four: First Steps,' starring Pedro Pascal as Reed, Vanessa Kirby as Sue, Joseph Quinn as Johnny and Ebon Moss-Bachrach as Ben. To marshal Marvel's First Family into the MCU, studio chief Kevin Feige tapped veteran director Matt Shakman, who helmed every episode of Marvel's first streaming series, 'WandaVision,' as well as episodes of 'Monarch: Legacy of Monsters,' 'Succession,' 'Game of Thrones,' 'The Great,' 'The Boys,' 'Fargo,' 'The Good Wife' and 'It's Always Sunny in Philadelphia.' More from Variety Marvel Studios Skipping Comic-Con Hall H Panel for 2025 As Comic Book Movies Scale Back Releases, Marvel and DC Look to This Summer to Decide the Future of Superhero Cinema David Tennant Says He Had His 'Eye On' the Role of Reed Richards in 'The Fantastic Four' Before Pedro Pascal Was Cast: 'They've Gone in a Different Direction' Beyond his extensive resume, Shakman's biggest qualification for the job is his love for the Fantastic Four comics, as demonstrated in the foreward the filmmaker penned for the new Marvel Premiere Collection release, 'Fantastic Four: Solve Everything' — which Variety is exclusively previewing below. The volume, which goes on sale June 3, is a streamlined collection of Fantastic Four comics published between 2009 and 2011 (i.e. issues #570–588) written by Jonathan Hickman, with art by Dale Eaglesham, Neil Edwards and Steve Epting, and cover art by Joe Quesada. In his foreward, Shakman singles out Hickman's work — and this particular run of issues — as a major influence on the new 'Fantastic Four' movie. Among several curious allusions to FF storylines and characters, the director specifically cites three of Hickman's inventions — Reed's philanthropic Future Foundation, the multiverse portal the Bridge, and the interdimensional Council of Reeds. How these may (or may not) be incorporated into the movie remains to be seen, but Shakman's love for the comics, and for these characters, is abundantly clear. Fantastic Four: Solve EverythingForeward By Matt Shakman I fell in love with the Fantastic Four when I was a kid growing up in Ventura, California. Encountering a family of super heroes that felt so familiar blew my mind: the humor, the heart, the sniping and griping, the messiness. At the same time, I was taken by the optimism and wonder of their world. With their roots in the '60s space race, the F4 have always been about exploration — whether it is to the cosmos or the Negative Zone or deep into the human mind. Reed, Sue, Ben and Johnny may have incredible powers, but they are family first, scientists and explorers second and super heroes only when absolutely necessary. Every Marvel filmmaker attempts to build on what has come before in publishing while simultaneously reinventing the characters for the current moment. The same is true with comic creators. What Lee and Kirby launched in the '60s changed Marvel forever. Their bold gamble to center a realistic family turned into the biggest hit of the early Silver Age. Every artist and writer since has attempted to build on that legacy while finding something in the characters that made them sparkle anew. In preparation for Marvel Studios' 'The Fantastic Four: First Steps,' I delved into the 60-plus years of comics history. Marvel's First Family has been continuously cared for by the best and brightest the company had to offer. None shone so bright as Jonathan Hickman. The humor and heart I loved as a kid? It's there and better than ever. The messy family dynamics? Made even more interesting as Val and Franklin take center stage. And that sense of optimism and wonder? I don't think the Fantastic Four have been quite as fantastic as they are in the pages of this book. As we developed the script for the film, I returned again and again to this epic run — thrilled by brain-bending innovations like the Council of Reeds and riveted by heroic standoffs against the likes of Annihilus. But it was Hickman's deep insight into the specific family dynamics of the Four that affected me the most. His Reed Richards is part Steve Jobs and part Oppenheimer, always on the edge of saving the world or destroying it. The author runs right at Mister Fantastic's weakness: believing that he can and should do it all on his own. Reed is determined to 'Solve Everything' — but he learns that the cost of solving everything is… everything. Ultimate knowledge risks ultimate sacrifice: the loss of his family. Sue has come a long way from the 'Invisible Girl' of the early '60s. In these pages, she is part United Nations Secretary General and part Field Marshal, backing up diplomacy with force when necessary. Hickman's Sue may be the most powerful member of the Four — she's the glue that holds the world together while Reed experiments in the lab with things that could destroy it. She brokers deals as the world's finest diplomat, ending up as the Queen of the Sea. In one of my favorite F4 moments, she declares to Namor, 'I am a Queen that bows before no King.' Damn right. How do these two very different people make up the greatest marriage in comics history? We see, page after page, that the secret is their unique balance of heart and mind. Before Jerry Maguire, these two completed each other. Sue and Reed are relatable not just as partners, but also as parents. We understand their anxiety, fretting over the destiny of Val and Franklin just as I fret over my 9-year-old daughter's future. I cherish the family intimacy of scenes in the Baxter Building and never doubt that these parents love their children and would do anything to protect their future. I know that Johnny and Ben would do the same. And we know that, as super heroes, they will fight just as hard to protect our world. Having absorbed six decades of F4 publishing, many of Hickman's magical moments and unique character dynamics stick with me. And they made it into our film in small and large ways. From Sue as a diplomat to Reed trying to solve everything even at the risk of imperiling his family. Johnny's need to be taken seriously. Ben's gentle nature, forever at odds with his appearance. The Future Foundation. The Bridge. The mystery of children and the anxiety we have as parents about their future. Hickman is a poet, of both the everyday and the extraordinary. His work beats with a heart as big as Sue Storm's, rendering an emotional journey that culminates in a scene that makes me tear up every time I read it. (I won't ruin it… just wait for 'Uncles.') His writing is thrilling, thought-provoking and tender…and, like the characters he writes about, fantastic.

Scarlett Johansson Asked to Have ‘Thunderbolts*' EP Credit Removed, Says Marvel Casts Get ‘So Enormous' You Sometimes ‘Feel Like a Device' to Move the Plot Along
Scarlett Johansson told David Harbour during a conversation for Interview magazine that she asked Marvel to remove her executive producer credit for 'Thunderbolts*,' the Marvel tentpole that opened in theaters in May. Harbour headlined 'Thunderbolts*' alongside Florence Pugh, Sebastian Stan, Julia Louis Dreyfus and more. Harbour and Pugh originally made their MCU debuts opposite Johansson in 'Black Widow.' 'It's the opening day of a movie that basically you are the seventh Thunderbolt in. Your character is all over this movie…. You are an executive producer on it. Congratulations,' Harbour said during the chat. More from Variety Marvel's 'Vision' Lands 'Schitt's Creek' Star Emily Hampshire as E.D.I.T.H. 'The Fantastic Four' Director Matt Shakman Reveals the 'Magical' Comics That Inspired the Film in 'Small and Large Ways' (EXCLUSIVE) Marvel Studios Skipping Comic-Con Hall H Panel for 2025 'I asked to have my credit removed because I wasn't involved,' Johansson replied, more or less suggesting that contractual reasons were why she was credited. Elsewhere during their Interview magazine discussion, the 'Black Widow' co-stars found common ground over the annoyances that arise while playing the same character for a decade or more. Johansson played Black Widow in the MCU for 11 years. 'Some of the films that I did for Marvel engaged my character more than others,' she said. 'Like in 'Captain America: The Winter Soldier' with Chris [Evans], we were really dynamic. In some of the other films, the cast was so enormous and there was so much plot to serve that you start to feel like you're a device to move it along. And if you're committed to five and a half months of that, it's like, 'Okay. I can't paint my nails, I can't get a haircut.' These sound like silly problems, but your identity is wrapped up in this job for a long time, and if you're not doing engaging work as an actor, you feel a little cagey sometimes.' Harbour can relate to Johansson after playing Hopper on Netflix's 'Stranger Things' for nearly 10 years. The series comes to an end with its fifth and final season this upcoming holiday season. 'When I started I loved it so much,' Harbour said. 'Buddies of mine who'd done TV shows for many years said, 'By season three or four you'll be running.' And I was like, 'Never! I love all these guys so much.' And then you get to a certain point where you're like, 'How much more story is there?' You're having to play a lot of the same beat, and there's a feeling where you're like, 'I want to take a risk. I want to do something that people haven't seen me do before.' So yeah, after 10 years, it's like, 'Okay.'' Johansson's Black Widow was killed off in 2019's 'Avengers: Endgame.' The standalone 'Black Widow' movie served as a prequel. The actor has stressed in the years since that she does not plan on returning to Marvel. 'It would be very hard for me to understand in what capacity [returning] would make sense for me, for the character that I play,' Johansson told Vanity Fair earlier this year. 'I miss my buddies and really would love to be with them forever, but what works about the character is that her story is complete. I don't want to mess with that. For fans, too — it's important for them.' Head over to Interview's website to read Johansson's latest interview with Harbour.
