Note that a worm hole that connects points ‘A’ and points ‘C’ in space does not violate casualty because events happen in proper time order. However, a wormhole that connects ‘A’ with ‘B’ is actually outside the time curve and reflects travel back in time violating causality.
Do wormholes violate special relativity?
(1) Wormholes are a type of curved spacetime. Therefore there can’t be any complete analysis of this problem in special relativity. You need general relativity.
Why does FTL violate causality?
What you need to understand is that faster than light travel breaks causality so that it is inconceivable that some new invention is going to let us do it. Otherwise, we can have faster than light speed travel before we invent it!
Do wormholes follow the laws of physics?
“The jury is not in, so we just don’t know,” physicist Kip Thorne, one of the world’s leading authorities on relativity, black holes and wormholes, told Space.com. “But there are very strong indications that wormholes that a human could travel through are forbidden by the laws of physics.
Does warp drive violate causality?
It definitely breaks causality, provided you have more than one drive, or the ability for the thing to turn around.
Are wormholes FTL?
Wormholes are an attractive approach to FTL technology because they don’t require you to break the speed of light. Physics tells us nothing can go faster than light. But with wormholes — shortcuts, basically — spacecraft could enter and exit at sub-light speeds.
Would an Alcubierre drive break causality?
The Alcubierre drive most certainly does violate causality, and this follows from just the most basic amount of Special Relativity that you might learn if only you’d spend your time learning real things, rather than spreading disinformation.
Is an Einstein Rosen bridge possible?
Einstein and Rosen discovered that, theoretically at least, a black hole’s surface might work as a bridge that connected to a second patch of space. The journey might be as if you went down the drain of your bathtub, and instead of getting stuck in the pipes, you came out into another tub just like the first.
Where do wormholes lead?
For a simplified notion of a wormhole, space can be visualized as a two-dimensional surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance.
How do Tachyons violate causality?
Causality is a fundamental principle of physics. If tachyons can transmit information faster than light, then according to relativity they violate causality, leading to logical paradoxes of the “kill your own grandfather” type.
Does Quantum break causality?
In classical physics – and everyday life – there is a strict causal relationship between consecutive events. If a second event (B) happens after a first event (A), for example, then B cannot affect the outcome of A.
Is the speed of light the speed of causality?
It is accepted that the speed of light is the speed of causality. If we exceed the speed of light, the order of cause and effect breaks down. This happens as we see our surroundings moving backward in time.
How much energy would it take to open a wormhole?
And even if you could break the rules, you would need an enormous amount. As a very rough approximation, you would need the energy the sun produces over 100 million years to make a wormhole about the size of a grapefruit. No one knows how even an advanced civilisation could access that much negative energy.
Are wormholes part of string theory?
Wang has now worked on a scenario involving string theory, in which the fundamental ingredient of reality are tiny strings. If one of these strings breaks, it can create a traversable wormhole. “It contains energy, and when it breaks, that energy becomes two black holes at each end of the string,” says Wang.
Is entanglement a wormhole?
Theoretical physicists have forged a connection between the concept of entanglement—itself a mysterious quantum mechanical connection between two widely separated particles—and that of a wormhole—a hypothetical connection between black holes that serves as a shortcut through space.
Can spacetime be manipulated?
Fortunately, modern theoretical physics offers us a solution: manipulate space-time to move ourselves to other remote places in the cosmos without formally violating the universal speed limit.
Is jump drive possible?
If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Issac Asimov’s Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.
Is warp drive faster-than-light?
A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude.
Would a wormhole be a sphere?
In two-dimensional diagrams, the wormhole mouth is shown as a circle. Seen in person, a wormhole would be a sphere. A gravitationally distorted view of space on the other side can be seen on the sphere’s surface.
Why do wormholes collapse?
As long as a wormhole has a greater mass than any black hole it encounters, it should remain stable. If a wormhole encounters a larger black hole, the black hole may disrupt the wormhole’s exotic matter enough to destabilize the wormhole, causing it to collapse and likely form a new black hole, Gabella said.
Is a black hole an Einstein Rosen Bridge?
Indeed, Einstein himself, working at Princeton with Nathan Rosen in the 1930s, had discovered that the equations actually represent a black hole as a bridge between two regions of flat space-time a phenomenon known as an “Einstein-Rosen bridge”.
Is there a real warp drive?
Warp drive currently exists only as a plot device for science fiction stories, but it may not be long before traveling at the speed of light – and beyond – leaves the realm of the theoretical and becomes reality.
How much energy would a warp drive need?
Just a third of a gram of the stuff interacting with matter in the wrong way could release energy equivalent to the Hiroshima blast. That means White’s Alcubierre warp drive still requires the amount of energy equivalent to 1.5 million Hiroshimas — enough to wipe civilization off the Earth.
Why is it faster than light?
Because the concept of “speed” requires measuring a certain amount of distance traveled in space during a certain period of time, the concept of speed does not even physically exist beyond the speed of light. In fact, the phrase “faster than light” is physically meaningless.
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
