>If wormholes exist, they could magnify the light of distant objects by up to 100,000 times — and that could be the key to finding them, according to research published Jan. 19 in the journal Physical Review D.

>Wormholes are theoretical funnel-shaped portals through which matter (or perhaps spacecraft) could travel great distances. To imagine a wormhole, suppose all of the universe were a sheet of paper. If your starting point were a dot at the top of the sheet and your destination were a dot on the bottom of the sheet, the wormhole would appear if you folded that sheet of paper so the two dots met. You could traverse the entire sheet in an instant, rather than traveling the entire length of the sheet.

>Wormholes have never been proven to exist, but physicists have nonetheless spent decades theorizing what these exotic objects might look and how they might behave. In their new paper, the researchers built a model to simulate an electrically charged, spherical wormhole and its effects on the universe around it. The researchers wanted to find out whether wormholes could be detectable by their observed effects on their surroundings.

>Imagine you are 40-something and want to go on a date looking like you did 20 years ago. This is impossible in the classical physical world but not in the quantum world, which refers to the subatomic particles that are the foundation for all reality. Miguel Navascués and David Trillo, Spanish researchers from the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW), conducted several studies with Austrian researcher Philip Walther and the University of Vienna’s experimental physics group. The team published papers in Physical Review X, Quantum, Arxiv, Physical Review Letters and Optica on theoretical research and experiments proving it’s possible to “accelerate, decelerate and reverse the flow of time within arbitrary, even uncontrolled quantum systems.” These unique physical processes, capable of disrupting the normal course of time, are universal: they have the same effect on all particles, regardless of their nature and interaction with other systems.

>Greg Spanjers, program manager for rocket cargo at AFRL, said the military envisions a future when it could be cheaper to send cargo via rocket than by transport aircraft. In a national security or humanitarian crisis, a launch vehicle would fly from Cape Canaveral, for example, and either land on an austere field to deliver cargo or airdrop it.
>
>For the rocket cargo program to be viable, Spanjers said, DoD expects to use launch providers that fly frequently so they can offer competitive pricing. “To make this a success, we need a very high launch rate, and we need to have systems that reenter and that can bring a high down mass,” he added.

Also from the article

>If rocket cargo moves forward and the technology matures, the Space Force would take the lead in managing the program and procuring services, he said. “We’re already starting to actively plan for a program standup in the 2026 timeframe.”

Lastly from the article

>Horne said the military is “going to need that infrastructure on orbit, not just for cargo, storage and movement, but for a lot of other applications. We’re gonna need gas tanks in the future. We may even have places where we are manufacturing things,” he added. “We’re going to find military-unique ways to use that from a national security perspective.”

>Ever since the ESA commissioned ClearSpace's first project, ClearSpace-1 in 2019, the company has been on a mission to clear space junk.
>
>The mission consists of a giant four-armed robotic spacecraft that can grab space debris. Once the debris is captured, the spacecraft will send it down toward Earth, where it is expected to burn up in the atmosphere.
>
>While the initial plan was to launch ClearSpace-1 in 2025, the tentative year of launch has been moved to 2026, following the recent review. The mission's primary target will be the upper stage of the VEga Secondary Payload Adapter (VESPA) which was launched by the ESA rocket in 2013.

>We as Americans don’t often hear about this chaotic process of displacement and relocation, but the scale of movement is already overwhelming: more than 3 million Americans lost their homes to climate disasters last year, and a substantial number of those will never make it back to their original properties. Over the coming decades, the total number of displaced will swell by millions and tens of millions, forcing Americans from the most vulnerable parts of the country into an unpredictable, quasi-permanent exile from the places they know and love.
>
>This migration won’t be a linear movement from point A to point B, and neither will it be a slow march away from the coastlines and the hottest places. Rather, the most vulnerable parts of the United States will enter a chaotic churn of instability as some people leave, others move around within the same town or city, and still others arrive only to leave again. In parts of California that are ravaged by wildfire, disaster victims will vie against millions of other state residents for apartments in the state’s turbulent housing market. In cities like Miami and Norfolk, where sea levels are rising, homeowners may watch their homes lose value as the market shies away from flood-prone areas. The effects will be different in every place, but almost everywhere the result will be the same: safe shelter will get scarcer and more expensive, loosening people’s grip on the stability that comes with a permanent home.
