Warning: Contains spoilers for Fantastic Four #25
Fantastic Four #25 – written by Ryan North, with art by Carlos Gomez – sends the crew on an accidental expedition to an alien world when they try to a completely new Marvel alien species, the untranslatable "Kkkkkk," who resemble massive many-legged insects.
Reed eventually realizes they've been in the same location all along. The Kkkkkk are from Earth in a time when no collision with the planet Theia occurred, and Mister Fantastic invents the Quantum Flux Accelerator to "add a time space-time frame to the multiverse" so both Earths can survive separately.

By developing the Quantum Flux Accelerator, Reed was able to alter the Multiverse in a way no one else has managed.
Weird happenings are the a romantic relationship with one of them, making the decision they're eventually faced with even more difficult. By the time Reed realizes that the two planets are actually the same, it seems like the only answer is to choose which species will survive by picking the surviving timeline. It is, as he puts it, an impossible choice, and one they truly have no right to make.
Rather than doom the Kkkkkk to save humanity, or vice versa, he truly outdoes himself. Reed Richards has come up with all manner of inventions. He's traveled through time, waged war against vampires, and can generally make anything work when inspiration strikes. Yet, by developing the Quantum Flux Accelerator, Reed was able to alter the Multiverse in a way no one else has managed. There is no magic or chance involved, only science and his own mind. It puts an inconceivable amount of power in Reed's hands, and the only sacrifice it requires is that the two universes remain separate forever.
The Quantum Flux Accelerator Grants Reed Richards Extraordinary Power
But It Has Its Limits
Though used with relative ease and safety at the climax of Fantastic Four #25, Reed's new Quantum Flex Accelerator could have a major impact on the Marvel Universe down the line.
The Quantum Flux Accelerator seems to require highly specific circumstances to work. Reed could only separate the universes during one highly specific moment in time, so in its current state, it wouldn't grant him the ability to split off timelines completely on a whim. Yet it still does the previously unimaginable. It could isolate other volatile points and remove them into their own timeline, which is particularly relevant with Dr. Doom as Sorcerer Supreme. The entire debacle with Kkkkk was seemingly caused by Doom and an unintended side effect of the Latverian dome, which means further instability could happen.
For the time being, Victor von Doom may not realize that he nearly extinguished life as they know it, but Marvel supergenius Mister Fantastic cleaned up his mess with a radical invention. Though used with relative ease and safety at the climax of Fantastic Four #25, Reed's new Quantum Flex Accelerator could have a major impact on the Marvel Universe down the line. Mr. Fantastic is the first person to create a new branch in the Multiverse using technology, and it may not be the last time the Fantastic Four does it.
