Do the laws of physics place a hard limit on how far technology can develop, or could an advanced civilization re-write those laws?

Three researchers published their findings this week in the journal Physical Review Letters and say their hypothesis is based on problems with the Hubble Constant, the rate at which the universe expands. Yesterday’s SciTechDaily report on the study says predictions for that constant are a lot slower than what we’ve measured in reality, and scientists are trying to figure out what’s causing the discrepancy. They say the cause could be a mirror world we can’t yet see.
“This might provide a way to understand why there appears to be a discrepancy between different measurements of the Universe’s expansion rate,” researchers said in a statement about their findings.
Scientists have long built models of the cosmos. Now the task is to create one that doesn’t violate any of the rules cosmological rules we’ve learned so far. The researchers say that if the universe is somehow exploiting what we know about its physics and symmetry there could be an invisible mirror world very similar to ours but invisible except through gravitational impact on our world.

You’d be instantly where you want to be if you moved at the speed of light. Indeed, light-speed travel has been a fantasy of many scientists and aerospace engineers who look for ways to achieve it.
And now, it seems Elon Musk and NASA have broken that fantasy code to build a light-speed engine that defies the laws of physics.

It’s said that the clock is always ticking, but there’s a chance that it isn’t. The theory of “presentism” states that the current moment is the only thing that’s real, while “eternalism” is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don’t tell us who wins the big game next year.

Researchers at the Department of Energy’s Oak Ridge National Laboratory are teaching microscopes to drive discoveries with an intuitive algorithm, developed at the lab’s Center for Nanophase Materials Sciences, that could guide breakthroughs in new materials for energy technologies, sensing and computing.
“There are so many potential materials, some of which we cannot study at all with conventional tools, that need more efficient and systematic approaches to design and synthesize,” said Maxim Ziatdinov of ORNL’s Computational Sciences and Engineering Division and the CNMS. “We can use smart automation to access unexplored materials as well as create a shareable, reproducible path to discoveries that have not previously been possible.”
The approach, published in Nature Machine Intelligence, combines physics and machine learning to automate microscopy experiments designed to study materials’ functional properties at the nanoscale.
