Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there faster, they could dig a tunnel straight through the mountain to create a shortcut. That’s the idea behind a wormhole.

A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other. Instead of traveling for many millions of years from one galaxy to another, under the right conditions, one could theoretically use a wormhole to cut the travel time down to hours or minutes.

Because wormholes represent shortcuts through space-time, they could even act like time machines. You might emerge from one end of a wormhole at a time earlier than when you entered its other end.

A sci fi documentary looking at a timelapse of future spacecraft. From the future of AI spaceships, Starship orbital refuelling, and space station worlds, to Mars colonization and in-space manufacturing.

Other topics include: SpaceX and the launch of their fleet of Starships — waiting in parking orbit around Earth, ready for the launch window to open to Mars. NASA and the mission of landing on the Martian Moon Phobos. Advances in spacecraft technology for protecting humans during multi-year interstellar journeys.

While the year 2100 and beyond, brings wormhole exploration, artificial intelligence based planets, and the possible need for a stellar engine — to protect the solar system.

Physicists from TU Delft, ETH Zürich and the University of Tübingen have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency signals, which may be useful in the hunt for dark matter. Their work will be published as an open-access article in Science Advances on Aug. 26.

If you bring two objects of different temperature together, such as putting a warm bottle of white wine into a cold chill pack, heat usually flows in one direction, from hot (the wine) to cold (the chill pack). And if you wait long enough, the two will both reach the same temperature, a process known in physics as reaching equilibrium: a balance between the heat flow one way and the other.

If you are willing to do some work, you can break this balance and cause heat to flow in the “wrong” way. This is the principle used in your refrigerator to keep your food cold, and in efficient heat pumps that can steal heat from the outside to warm your house. In their publication, Gary Steele and his co-authors demonstrate a quantum analog of a heat pump, causing the elementary quantum particles of light, known as , to move “against the flow” from a hot object to a cold one.

NGC 7,727 will someday merge with a nearby galaxy — and intertwine their black holes in the process.

The galaxy’s violent past is written into its shape and composition, and the details are visible via telescope. This week, the European Southern Observatory released a new image of NGC 7,727 taken with the ground-based Very Large Telescope (VLT).

Captured in visible light with the VLT’s FOcal Reducer and low dispersion Spectrograph 2 instrument, streams of dust kicked up by the two merging galaxies can be seen spiraling around NGC 7727. Bright blue and purple clusters of stars dot the inner arms of the galaxy.

And its lopsided shape is no coincidence: as its two parent galaxies spun dusty circles around each other, the newly-formed NGC 7,727 came into being in a rather uneven way.

A black hole is matter and/or light crammed into such a tiny volume that nothing can escape. But, shortly after the big bang, the observable universe was that small. How did it escape?! Brilliant for 20% off: http://brilliant.org/ScienceAsylum.

Finally, there’s the issue that black holes can destroy information. Once you have crossed the event horizon, it seems you’d need to move faster than light to get back out. But a non-local connection across the horizon would also get information out. Some physicists have even suggested that dark matter, a hypothetical type of matter that supposedly makes up 85% of matter in the universe, is really a misattribution. There may be only normal matter, it’s just that its gravitational attraction is multiplied and spread out because places are non-locally connected to each other.

A non-locally connected universe, hence, would make sense for many reasons. If these speculations are correct, the universe might be full with tiny portals that connect seemingly distant places. The physicists Fotini Markopoulou and Lee Smolin estimated that our universe could contain as much as 10,360 of such non-local connections. And since the connections are non-local anyway, it doesn’t matter that they expand with the universe. The human brain, for comparison, has a measly 1015connections.

Let me be clear that there is absolutely zero evidence that non-local connections exist, or that, if they existed, they’d indeed allow the universe to think. But we cannot rule this possibility out either. Crazy as it sounds, the idea that the universe is intelligent is compatible with all we know so far.
