Real-life wormholes may not be that far-fetched

It might sound like science fiction, but the idea of linking two black holes together actually does have some merit.
On the face of it, a wormhole might seem like a straight forward concept - link two black holes in different parts of the cosmos to create a tunnel through which a space traveler could pass.

In reality however, it's not quite that simple.

It's certainly an idea that has been around for a while - physicists Albert Einstein and Nathan Rosen took a very serious look at the concept in connection with Einstein's general theory of relativity.

Even today, scientists are still attempting to determine if wormholes could actually work in practice.

Although we've never discovered or observed an actual wormhole, some physicists believe that they could exist, albeit with some caveats that have yet to be overcome.
For one, the gravitational attraction between the wormhole and the matter passing through it would force it to close, thus requiring the involvement of some form of 'exotic' matter to keep it open.

Secondly, the processes involved would make the wormhole microscopic in size - a far cry from the wormhole in Star Trek: Deep Space Nine for instance which was traversable by entire fleets.

These issues haven't stopped scientists from working on the problem, however, with studies involving the use of quantum entanglement, for instance, showing some promise in maintaining stability.

Increasing the size of the wormhole, however, still represents something of a challenge.

So while we are certainly a long way from proving that wormholes through space could actually exist, it would also be a stretch at this point to conclude that they could never exist at all.

I'm not sure I understand this. What exactly is vibrating here, and does lowering/raising the vibration refer to the amplitude or frequency? And how do you modify the vibrations?

Wormholes and black holes aren't the same thing. A wormhole (or Einstein–Rosen bridge or Einstein–Rosen wormhole) is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations. A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, or different points in time, or both). Wormholes are consistent with the general theory of relativity by Einstein, but whether wormholes actually exist remains to be seen. Many scientists postulate that wormholes are merely projections o... [More]

The rate at which the atoms of our matter vibrate. The Philadelphia and Montauk projects, were US military projects from the 40s and early 80s. The basis of the earlier project Philadelphia was creating an EM bubble (for cloaking) around an aircraft carrier that was stationed in Philadelphia back in the 40s. It had been speculated this EM bubble was what allowed UFOs to go invisible and was replicated to disastrous effect. Everything's matter that was within this generated EM bubble shaped field was tuned differently than the matter outside the field and which caused the ship to vanish. Mistak... [More]

How are you measuring this?

I have never understood when physics says black holes are not holes but dense objects, actual physicists themselves then come out talking like they are. Whats that about?
Comment icon #10 Posted by Waspie_Dwarf 2 years ago
They are known as black holes because, being extremely dense objects, anything that gets too close falls in and can not escape... even light.

Yet you have scientists which despite the science trying to make out there are actual holes, holes to other universes, holes allowing wormholes, etc.

What's known is that there are superdense bodies floating around in space. These bodies are dense enough to have a gravitational effect on everything that enters their gravitational range, down to the most massless particles. These are black holes. As I understand the speculation (and this is probably oversimplified, I'm not an astrophysicist), a large/dense enough black hole will actually interact with whatever "space" itself is made of, pulling a unit of "space stuff" closer than it would be normally, allowing accelerated travel between two points. Of course, the trick here is to access the ... [More]
