The real magic of Fermi problems lies in their imperfection. They remind us that it’s okay to be wrong — as long as you’re thoughtfully wrong. “There are no wrong answers,” says Funk. “It’s about the process.”
No single formula exists. Yet each problem invites the same approach: break it down, make realistic (or at least consistent) assumptions, and trust your critical thinking. “No Wrong Answers” is a common Fermi problem refrain because even if your math arrives at a slightly off result, you’ve shown how you reason. And that, ultimately, is the real answer.
So, the next time you’re faced with a seemingly impossible question — whether it’s How many grains of sand are on all the world’s beaches? or How long would it take to drive to the moon? — grab a napkin and a pen. Start breaking it down. Make some guesses. Do some math. You might just surprise yourself with how close you can get.
To travel between the stars requires vast amounts of fuel and energy, but as it turns out, the ocean of night in deep space is full of fuel, if you can collect it along the way.

Two new recently published, peer-reviewed scientific papers show that real warp drive designs based on real physics may be possible. They are realistic and physical, which had not been the case in the past. In a paper published in 1994, Mexican physicist Miguel Alcubierre showed theoretically that an FTL warp drive could work within the laws of physics. But it would require huge amounts of negative mass or energy. Such a thing is not known to exist.

In a recent paper published by Applied Physics, authors Alexey Bobrick and Gianni Martire, outline how a physically feasible warp drive could in principle, work, without the need for negative energy. I spoke to them. They had technical input on this video.
What Alcubierre did in his paper is figure out a shape that he believed spacetime needed to have in order for a ship to travel faster than light. Then he solved Einstein’s equation for general relativity to determine the matter and energy he would need to generate the desired curvature. It could only work with negative energy. This is mathematically consistent, but meaningless because negative mass is not known to exist. Negative mass is not the same as anti-matter. Antimatter has positive energy and mass.
Theoretical warp technology exists in what we know as the Alcubierre drive. In this video, I will explain how this theoretical warp technology works and the problems that we face in developing it.
You will also get to see some mathematically accurate simulations of a spaceship using an Alcubierre drive, travelling at 1,000 light years per second!
In Star Trek, Star Wars, Dune and many other sci-fi stories where space travel exists, the common question that viewers have is: how do these humans achieve faster than light travel? The term “Warp travel” and “Warp speed” were originally coined by the Star Trek franchise. It is also known by other franchises as “Jump” or “folding of space” and the engines that cause this to happen are the “warp drive” or the “hyper drive”
Ultimately, the idea of bending space is embedded within all of these sci-fi stories, and with good reason.
It is impossible to travel faster than light within space. But space itself can bend, fold, move, expand at any speed or rate.
The alcubierre drive uses the principals in general relativity to bend space around a spaceship in such a way, that the space itself begins to move, carrying along anything within it. So although the spaceship is not technically moving within the space it occupies, the space around the spaceship allows motion to occur.
Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions. Go faster, farther, more efficiently.
That’s the goal driving spacecraft propulsion engineers like Chen Cui, a new assistant professor at the University of Virginia School of Engineering and Applied Science. Cui is exploring ways to improve electric propulsion thrusters — a key technology for future space missions.
“In order to ensure the technology remains viable for long-term missions, we need to optimize EP integration with spacecraft systems,” Cui said.
Scientists have created over a million simulated cosmic images using the power of supercomputers to anticipate the capabilities of NASA
NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for the nation’s civilian space program and for aeronautics and aerospace research. Established in 1958 by the National Aeronautics and Space Act, NASA has led the U.S. in space exploration efforts, including the Apollo moon-landing missions, the Skylab space station, and the Space Shuttle program.
New Shepard is a rocket manufactured by Blue Origin for space tourism, however the newest mission will be simulating the Moon’s gravity and flying 30 payloads to test lunar related technology. \r.

3D printing news News NASA and Rocket Lab Enter a New Era With the Neutron Rocket.
Published on January 27, 2025 by Madeleine P.
With the goal of further expanding its reach in space missions, NASA has signed an agreement with Rocket Lab USA, Inc. to integrate the Neutron rocket into the VADR program. This is a program to procure launch services at competitive prices and reduce mission requirements for spacecraft that have not yet been launched into orbit. Neutron is a medium-range launch vehicle manufactured by Rocket Lab USA that is partially reusable and powered by nine 3D-printed Archimedes engines designed to increase the efficiency and flexibility of space launches.
