Imagine this: In the far, far future, long after you’ve died, you’ll eventually come back to life. So will everyone else who ever had a hand in the history of human civilization. But in this scenario, returning from the dead is the relatively normal part. The journey home will be a hell of a lot weirder than the destination.

Here’s how it will go down: A megastructure called a Dyson Sphere will provide a superintelligent artificial agent (AI) with the enormous amounts of power it needs to collect as much historical and personal data about you, so it can rebuild your exact digital copy. Once it’s finished, you’ll live your whole life (again) in a simulated reality, and when the time comes for you to die (again), you’ll be transported into a simulated afterlife, à la Black Mirror’s “San Junipero,” where you’ll get to hang out with your friends, family, and favorite celebrities forever.

Yes, this is mind-boggling. But someday, it might also be very real.

On track to hit the hundreds of thousands that they projected for 2025?


Honeywell has upgraded the commercial trapped ion quantum computer System Model H1 and achieved a quantum volume of 512. This is four times higher than when it was released in September 2020 with a quantum volume of 128. This is the highest measured on a commercial quantum computer to date. It is the third time in nine months Honeywell has set a record for quantum volume on one of its systems.

Creating 200 billion-plus brand-new red blood cells a day can take a toll on a body. The capacity to replace components charged with the life-sustaining task of carrying oxygen eventually wears out with aging, resulting in health problems, from anemia to blood cancers.

What if we could halt the aging process and maintain young blood cells for life? With blood cells making up a whopping 90% of the body’s cells, it makes sense that keeping them abundant and fit could boost vitality into our golden years.

Now, a group of researchers, including experts at the University of Colorado Anschutz Medical Campus, has discovered ways to do just that – keep the blood manufacturing process flowing. The work, recently published in the journal Nature, could open doors to everything from disease-preventive therapies to better blood banks.

SpaceX’s Starship SN11 prototype rolled out to its test stand Monday (March 8) at the company’s facility near Boca Chica Village in South Texas.


It’s been less than a week since SpaceX’s epic Starship SN10 rocket landing (and subsequent explosion) and the company is already gearing up for another test flight.

The latest Starship incarnation, the SN11 prototype, rolled out to its test stand Monday (March 8) at SpaceX’s proving grounds near Boca Chica Village in South Texas ahead of an upcoming launch. It is expected to launch on SpaceX’s fourth high-altitude Starship flight soon.

The aviation industry is a terrible emitter of greenhouse gases. In 2019, it emitted 918 million tons of carbon dioxide into the environment. To solve this problem, aircraft must go green. One solution is battery-powered airplanes. Battery-powered airplanes have existed for decades and with improvements in battery technology, could become widespread in the near future. However, for long-distance intercontinental flights, we will need hydrogen airplanes. Hydrogen airplanes are also very feasible and could be used with turbofan technology, producing only water as emissions.
