Kaku spotted alone

A fan spotted Michio Kaku walking alone, probably coming back from picking up his mail at the end of his several mile long driveway, on the afternoon of March 18, 2026. Was he all alone? “Definitely yes,” says the fan, adding that “He was wearing a large sweater and looked really cute!”

Is Michio back on the market?

A rep for Michio Kaku was not immediately available for comment.

Truth or rumor, when news that the scientist was splitting hit the internet Thursday (March 19), Twitter immediately exploded with pithy commentary. It seems everyone had an opinion on the matter:

“Has anyone Michio’s phone number?”

“So very sad… Those 2 were so great as a couple. So cute together.”

Based on the facts (Kaku spotted alone with a cute sweater), is there trouble in paradise or is it much ado about nothing?
