With all my enthusiasm for humanity's future in space, there's one glaring problem. We are soft meat bags of mostly water, and those other stars are really far away. Even with the most optimistic spaceflight technologies, we can imagine, we are never going to reach another star in a human lifetime.

Reality tells us that even the most nearby stars are incomprehensibly far away, and would require vast amounts of energy or time to make the journey. Reality says that we would need a ship that can somehow last for hundreds or thousands of years, while generation after generation of astronauts are born, live their lives and die while travelling to another star.

Science fiction, on the other hand, woos us with its advanced propulsion, warp drive, making a journey to the closest Star System, Alpha Centauri a quick ride. You know what's even easier? A wormhole; a magical gateway that connects two points in space and time with one-another.

Yeah, that would be really nice. Someone should really get around to inventing these wormholes, that will unfold new future of inter-galactic speed walking. But What are wormholes, exactly?

A wormhole, also known as an Einstein-Rosen bridge is a theoretical method of folding space and time so that you could connect two places in space together. You could then travel instantaneously from one place to another.

While wormholes are theoretically possible to create, they are practically impossible from what we currently understand.

The first big problem is that. wormholes aren't traversable according to General Relativity. So keep this in mind; physics that predicts these things, prohibits them from being used as a method of transportation. That's a pretty serious strike against them.

Second, even if wormholes can be created, they would be completely unstable, collapsing instantly after their formation. If you tried to walk into one end, you might as well be walking into a black hole.

Third, even if they are traversable, and can be kept stable, the moment any material tried to pass through – even photons of light – that would make them collapse.

Back in 2015, researchers in Spain created a tiny magnetic wormhole for the first time ever. They used it to connect two regions of space so that a magnetic field could travel invisibly between them.

Before you get too excited, it was not the kind of gravitational wormhole, that would theoretically allow humans to travel rapidly across space and transport matter, as we see in science fiction TV shows and films, such as Stargate, Star Trek, and Interstellar.

But the physicists managed to create a tunnel that allowed a magnetic field to disappear at one point, and then reappear at another, which is still a pretty huge deal.

A wormhole is effectively just a tunnel that connects two places in the Universe. So far scientists have simulated this process, but they are nowhere near in creating a gravitational wormhole, as it would require us to create huge amounts of gravitational energy - something we don't yet know how to do.

Unusual flashes of gamma rays could reveal that what appear to be giant black holes, are actually huge wormholes.

Wormholes are tunnels in space-time, that can theoretically allow travel anywhere in space and time, or even into another universe. Einstein's theory of general relativity suggests, wormholes are possible, although whether they really exist is another matter.

In many ways, wormholes resemble black holes. Both kinds of objects are extremely dense and possess extraordinarily strong gravitational pulls. The main difference is that no object can theoretically come back out, after crossing a black hole's event horizon — the threshold where the speed needed to escape the black hole's gravitational pull exceeds the speed of light — whereas any body entering a wormhole could theoretically reverse course, which means you can escape out of a Worm Hole.

Assuming wormholes might exist, researchers investigated ways that one might distinguish, a wormhole from a black hole. They focused on supermassive black holes, with masses millions to billions of times that of the sun, which are thought to exist at the centre of most of the galaxies. For example, at the center of our MilkyWay galaxy lies Sagittarius A, a monster black hole that is about 4.5 million solar masses in size.

Anything entering one mouth of a wormhole would exit out from its other mouth. The scientists reasoned that meant that matter entering one mouth of a wormhole could potentially collide with the matter entering the other mouth of the wormhole at the same time, a kind of event that would never happen with a black hole.

Any matter falling into a mouth of a supermassive wormhole would likely to travel at extraordinary high speed due to its powerful gravitational field. The result of such collisions are, spheres of plasma expanding out both mouths of the wormhole at nearly the speed of light.

The researchers compared the outbursts from such wormholes with those from a kind of supermassive black holes, which can spew out more radiation than our entire galaxy does, and so they from a patch of space no larger than our solar system around them. While supermassive black holes are typically surrounded by rings of plasma known as accretion disks and can emit powerful jets of radiation from their poles.

The spheres of plasma from wormholes, can reach temperatures of about 18 trillion degrees Fahrenheit, that is 10 trillion degrees Celsius. At such heat, the plasma would produce gamma rays with energies of 68 million electronvolts.

In contrast, Accretion disks of Super Massive Blackholes don't emit gamma radiation, because their temperature is too low for that, although jets from SuperMassive Blackholes can emit gamma rays, these would mostly travel in the same direction as the jets, but if jets are traveling out in a sphere, might suggest, they came from a wormhole.

In addition, if a SuperMassive Blackholes resided in a kind of galaxy known as a Type I Seyfert, one in which hot gas was expanding rapidly, prior work suggested, it would likely not generate many gamma rays, with energies of 68 million electronvolts. If astronomers did see a SuperMassive Blackholes in a Type I Seyfert galaxy, with a significant peak of such rays, that could mean that seeming SuperMassive Blackhole was actually a Wormhole.
