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.
Can Scientists create Worm Holes In Labs ? Will It ever be
possible to create Worm Holes?
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.
Are some black holes wormholes in disguise? Gamma-ray blasts,
may shed clues
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.
