Abstract: We present a comprehensive tutorial on the finite-difference time-domain (FDTD) modeling of space, time, and space-time-varying media, building upon our previous review by offering a ...

Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests that the higher dimensional structure of spacetime could be the actual ...

As AI reshapes the workforce, many Gen Z college graduates are finding out the hard way that their degrees don’t guarantee a smooth career launch. Now, even OpenAI CEO Sam Altman—one of Silicon Valley ...

While Bill Gates has said the two-day workweek could come within the next decade, OpenAI CEO Sam Altman (above) says Gen Alpha college graduates will be too busy planet-hopping. With Gen Z facing ...

The time is ripe to end the “Wolf Amendment,” a congressional bar inhibiting civil collaboration between the United States and China in space. The impetus for the law was noble — an attempt to ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

Jeff Bezos’ Blue Origin space venture added a page to the space history books today by sending the first wheelchair user into space. “It was the coolest experience,” said Michaela “Michi” Benthaus, a ...

Michaela "Michi" Benthaus and teammates spent several minutes in microgravity. Blue Origin made history Saturday, sending for the first time a person who uses a wheelchair past the Kármán line, an ...

Could AI’s insatiable thirst for colossal data centres be fixed by launching them into space? Tech companies are eyeing low Earth orbit as a potential solution, but researchers say it’s unlikely in ...

Michaela 'Michi' Benthaus is an aerospace and mechatronics engineer at the ESA. Blue Origin will make history when it sends the first person who uses a wheelchair past the Kármán line, an ...
