• Scientists at the University at Buffalo and Case Western Reserve University in the US, and Yangzhou University in China have published new research in Physical Review D to detail a way to locate wormholes.

• In theory, a wormhole is a tubular structure that can link together two parts of space at totally different points in time and regardless of the distance between them. But as yet, mainstream science hasn’t proven that they actually exist.

• Wormholes, in theory, require the extreme gravitation conditions of an enormous black hole. The research scientists propose honing in on the supermassive black hole at the center of our galaxy known as Sagittarius A. If a wormhole exists there, then the stars near this black hole would be affected and create gravitational anomalies.

• The study’s co-author Dr Dejan Stojkovic notes that people and spaceships will not be able to travel through the wormhole until we find a source of negative energy to keep the wormhole open and stable. Says Stojkovic, “To create a huge wormhole that’s stable, you need some magic.”

 

Physicists have published a new methodology that will surely delight hardcore science fiction fans: a how-to guide for finding wormholes, a theoretical structure that provides passage between different areas of spacetime.

In theory, a wormhole could link together two parts of space at totally different points in time and regardless of the distance between them. However, reliable sci-fi plot device though they may be, no one knows if they really exist.

Now, scientists at the University at Buffalo and Case Western Reserve University in the US, and Yangzhou University in China have published new research in Physical Review D to detail a way to potentially locate wormholes.

They propose honing in on Sagittarius A*, believed to be a supermassive black hole right at the centre of our galaxy. Wormholes, in theory, require the extreme gravitation conditions of such an enormous black hole.

If a wormhole exists then the stars nearby would be affected by the gravity of stars on the other side of the wormhole’s tunnel, so the researchers argue that searching for anomalies in the orbits of the stars close to Sagittarius A*.

However, don’t get your hopes up about the prospect of time travel via wormhole just yet; study co-author Dr Dejan Stojkovic says that if wormholes even exist, then they’re probably not as we’ve seen them on our screens.

ESA Antenna Could Intercept Alien Messages From Black Holes, Scientists Say

• When launched, the next-generation ‘Laser Interferometer Space Antenna’ (LISA – pictured above) developed by the European Space Agency will be the first-ever space-based gravitational wave detector. It will consist of space probes arranged in a triangular formation with distance of about 2.5 million kilometers from each other.

• Professor Marek Abramowicz, the lead researcher from the University of Gothenburg in Sweden, believes that LISA may also be able to detect extraterrestrial communication. If the space antenna array were placed around a black hole, it could possibly decipher encrypted messages from an advanced alien civilization. Abramowicz said that that there is a chance of finding such an alien civilization if we know where to look. Technologically advanced civilizations may use the black hole’s innermost stable orbit to send messages to the rest of the galaxy.

• Abramowicz and his colleagues suggest that in the Milky Way, the central black hole called Sagittarius A* would be the ideal spot for a technologically advanced alien civilization to broadcast communications for the rest of the galaxy. “In order to be recognized as (a message), a gravitational wave Messenger beacon must emit a clearly unnatural signal, such as a persistent emission of gravitational waves at a constant frequency,” added Abramowicz.

• “We argue that if a sophisticated extraterrestrial civilization would decide to construct a device to study the massive black hole in the galactic center, or to extract energy from it, or even for intentions unfathomable to the human mind, this device can also serve as a Messenger,” Abramowicz explained.

• The ESA’s LISA is scheduled to launch into space to study gravitational waves by the year 2034.

 

A sophisticated space-based antenna developed by the European Space Agency (ESA) is designed to measure gravitational waves, but it could possibly also decipher encrypted messages from an advanced alien civilization, a new paper suggests.

A team of physicists suggested that the Laser Interferometer Space Antenna (LISA) would be able to detect messages from an advanced alien civilization if it is placed around a black hole where the hypothetical extraterrestrials could look to.

LISA is the next-generation space instrument that is designed by ESA to detect and measure gravitational waves from space. If successfully launched, it will be the first-ever space-based gravitational wave detector. It will consist of space probes arranged in a triangular formation with distance of about 2.5 million kilometers from each other.

Professor Marek Abramowicz, the lead researcher from the University of Gothenburg in Sweden, believes that LISA is the answer to uncovering alien life in the Milky Way galaxy.

“Gravitational waves phenomena are omnipresent in the universe and with sufficient technological prowess relatively straightforward to detect,” the researchers said, adding they believe LISA plays a role in detecting extraterrestrial communication.

With the number of habitable planets in our galaxy and the estimation of the existence of advanced alien life using the Drake Equation, Abramowicz said that that there is a chance of finding one if we know where to look.
