Time travel might be possible

Plus: US Air Force spends $1.2B to replace Cold War-era E-3 Sentry AWACS fleet.

Using lasers, Ronald Mallett is on a mission to develop a working time machine.

This may be tricky because, according to physics, time travel is impossible. But Mallett believes he has found a loophole.

His idea is to create an artificial black hole, which could generate a gravitational field that could lead to time loops and the ability to travel to the past. Since 2019, the prototype has produced a continuously rotating light beam.

But before you contemplate what we could do with that development, take a moment to contemplate this video. It shows the Cold War-era E-3 Sentry AWACS fleet, which the US Air Force is now spending $1.2B to replace.

Good morning. I’m Alice, an Editor at IE.

This is The Blueprint. Let’s dive in.

Compact nuclear fusion 1 million times more effective than other types, claims Israeli startup. The Israel Energy Ministry has pledged $11.5 million to establish a national nuclear fusion institute with funding to include NT-Tao, a local startup developing a compact nuclear fusion system.

Better late than never I suppose.

Time travel might be possible using spinning lasers, according to a physicist.

Ronald Mallett is on a mission to develop a working time machine that uses lasers.

This may prove hard because, according to what we know about physics, time travel is impossible.

But Mallett believes he has found a loophole. His idea is to create an artificial black hole, which could generate a gravitational field that could lead to time loops and the ability to travel to the past. Since 2019, the prototype has produced a continuously rotating light beam.

He said: “Initially, they constructed a wind tunnel to determine the optimal configurations for aircraft wings. Regarding the construction of a time machine, the wind tunnel must be constructed before the plane.”

Mallett believes his prototype will work, but it hasn't happened yet. And even if it does, he says the dip back in time will be limited.

→ “Imagine if we could predict precisely when earthquakes are going to occur, or tsunamis. So, I’ve opened the door to that possibility,” added Mallett.

INNOVATION

Fired engineer who called Google AI' sentient' warns Microsoft Bing is a 'train wreck.'

Blake Lemoine, the Google engineer fired for violating the company's confidentiality policy, has now expressed concerns about the risks associated with AI-driven chatbot s like Microsoft's Bing AI.

The latest AI models, according to him, are the most potent technological advancement since the atomic bomb and can alter the course of history fundamentally.

SCIENCE

Most detailed geological model reveals Earth's last 100 million years.

For the first time, a high-resolution dynamic model of the Earth's surface over the past 100 million years has been developed.

The detailed model will enable researchers to test different hypotheses on how the Earth's surface may react to shifting tectonic and climate factors. It will also boost knowledge of how the movement of Earth's sediment controls the carbon cycle over time.

CULTURE

Ancient Roman 'spike defenses' developed by Julius Caesar discovered in Germany.

Researchers in Germany might have uncovered the best-preserved example of a defensive structure he pioneered more than 2,000 years ago.

The so-called 'spike defense' was also known as "Roman barbed wire" and was written about by Julius Caesar during his Gallic Wars, which is Caesar's recounting of his military campaigns in modern-day France and Germany.

Time travel might be possible using spinning lasers.

Do you think we’ll be able to time travel in our lifetimes?

No, or ever for that matter

Yes, I’d like to think it’s possible

Maybe, but it seems unlikely

I am unsure either way
