Warp drives distort spacetime itself, just like binary mergers of compact objects like black holes and neutron stars. It’s theoretically possible that they emit a gravitational wave signal in the same vein as mergers

Would a warp drive create gravitational waves?

However, the collapse of the warp drive, or its acceleration or deceleration, should generate gravitational waves, and in this work, we study the first case by allowing the warp bubble to collapse

a warp drive scientifically possible?

A team of physicists from the University of Alabama in Huntsville and the Advanced Propulsion Laboratory at Applied Physics, in New York, has developed a model that shows it might be possible to create a subluminal warp drive

Will future humans use warp drives to explore the cosmos? We’re in no position to eliminate the possibility. But if our distant descendants ever do, it won’t involve dilithium crystals, and Scottish accents will have evaporated into history by then. 

Warp drives have their roots in one of the most popular science fiction franchises ever, but they do have a scientific basis. A new paper examines the science behind them and asks if a warp drive containment failure would emit detectable gravitational waves. 

The paper is titled “What no one has seen before: gravitational waveforms from warp drive collapse.” The authors are Katy Clough, Tim Dietrich, and Sebastian Khan, physicists from institutions in the UK and Germany.

Despite originating in science fiction, warp drives have a concrete description in general relativity, with Alcubierre first proposing a spacetime metric that supported faster-than-light travel. Whilst there are numerous practical barriers to their implementation in real life, including a requirement for negative energy, computationally, one can simulate their evolution in time given an equation of state describing the matter. In this work, we study the signatures arising from a warp drive “containment failure”, assuming a stiff equation of state for the fluid. We compute the emitted gravitational-wave signal and track the energy fluxes of the fluid. Apart from its rather speculative application to the search for extraterrestrial life in gravitational-wave detector data, this work is interesting as a study of the dynamical evolution and stability of spacetimes that violate the null energy condition. Our work highlights the importance of exploring strange new spacetimes, to (boldly) simulate what no one has seen before.

The principle idea behind a warp drive is that instead of exceeding the speed of light directly in a local reference frame, which would violate Lorentz invariance, a “warp bubble” could traverse distances faster than the speed of light (as measured by some distant observer) by contracting spacetime in front of it and expanding spacetime behind it,” the paper states.

Can we create gravitational waves?

The group of researchers behind this paper proposed that, in theory, a sufficiently highly powered “twisted” laser beam (one that can carry a component called orbital angular momentum) could generate high-frequency gravitational waves that we could detect in a lab

What are the gravity waves in the black hole merger?

Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo black hole may be much larger than previously thought

Did Albert Einstein predict gravitational waves?

Though Einstein predicted the existence of gravitational waves in 1916, the first proof of their existence didn’t arrive until 1974. In that year, two astronomers, Russell Hulse and Joseph Taylor, using the Arecibo Radio Observatory in Puerto Rico discovered a binary pulsar 21000 light years from Earth.

Does everything emit gravitational waves?

Technically speaking, every physical object that accelerates produces gravitational waves. This includes humans, cars, airplanes etc. But the masses and accelerations of objects on Earth are far too small to make gravitational waves big enough to detect with our instruments

Einstein’s gravity theory correct?

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes — and the Big Bang itself

Traveling through the universe faster than light. Wormhole and Warpdrive Technology

Friends, Proxima Centauri is the nearest star system to our Earth, which is located about 4.25 Light Years away from our solar system. If we travel at the speed of 700,000 kilometers per hour in the fastest spacecraft in human history – Parker Solar Probe. Still, it will take us 7000 years to reach our nearest star, which is quite a lot.

This is only about the Star System closest to us, scientists have also discovered some such Solar Systems located hundreds and thousands of Light Years away from our Earth. Where many alien planets can exist like our Earth, where life like our Earth and perhaps some intelligent life can also exist

Traveling Universe through Light Speed

Even if we think of traveling to such star systems at the speed of light, it will take us thousands of years just to reach these planets. It will take many generations of humans to complete such a journey and yet our journey will not be completed. “That is to say, in simple terms, the speed of light also appears very low compared to the size of our universe.”

Future techniques to travel faster than Light – Wormholes and Warp Drives

In such a situation, if we have to become Type 2 and Type 3 Civilization and have to travel to other star systems and their planets in our galaxy and bring life there. So we will have to work on some such vehicles and methods through which we can travel faster than the speed of light while cheating the principles of the universe.

How does spacetime work? What is Space Time and how it Works

Friends, before knowing about these methods, we need to know about Spacetime, what it is, how it works and how we can travel faster than light, deceiving the principles of the universe through the Loopholes present in it. is.

Most of our scientists’ understanding of spacetime is the contribution of Albert Einstein’s Theory of General Relativity. According to General Relativity, Space and Time are interconnected which is called Fabric of Spacetime. In simple language, you can consider Spacetime like a sheet on which the heavier the object we place, the more this sheet will bend or rather curve.

How can we bend Space Time? Space Time bend

Similarly, Mass and Energy bend Spacetime. Every space object present in the universe curves the spacetime around it, in such a situation, the greater the mass of the object, the greater is its spacetime curve, which we feel as the gravity of that object. In such a situation, objects with low mass are always attracted towards the curve of objects with high mass.

Space objects with very high mass present in our universe – such as giant stars and black holes curve this spacetime the most, due to which they have the highest gravity. The same scientists believe that the gravity of black holes is so high that it creates a hole in spacetime due to which even light is unable to cross its event horizon.

Hole in Spacetime Holes in Spacetime

In such a situation, Albert Einstein and his colleague Nathan Rosen believed that many holes could exist in spacetime, which would work to connect two different places in space. Let us try to understand this with the help of an example, suppose A and B are two different places in space whose distance is several light years.

If you want to cover the distance from A to B in the traditional way, it will take you millions to crores of years. But if we somehow succeed in bending spacetime, then using this shortcut we can travel the distance from A to B in a very short time, that too without breaking any law of the universe.

What are wormholes and how do they work?

These shortcut paths are called Wormholes which arise due to bends in spacetime. You must have seen glimpses of it in the famous scifi movie Interstellar, where one part of the Wormhole was in our solar system and the other part was in a distant star system.

Scientists believe that the Black Holes present in our universe may be connected to similar wormholes. Where the Blackhole absorbs everything around it and nothing can come back from its Singularity.

What is Warp Drive Technology and how does it work?

Friends, the second option is Warp Drive Technology. We have already learned how we can curve spacetime through excessive mass or energy. Science fiction writers like John Campbell and Asimov saw this warping of spacetime as a way to achieve speeds faster than the speed of light.

According to him, if we compress the space in front of a starship and expand the space behind it at the same speed, then we can achieve a speed faster than the speed of light without putting much effort.

Warp Drive Technology के उदाहरण

चलिए हम इसे MIT के एक प्रसिद्ध उदाहरण के जरिये समझने की कोशिश करते है | मानलीजिए हमारा Space एक Slinky है जिसके एक तरफ है हमारी पृथ्वी तो दूसरी तरफ है कई प्रकाशवर्ष दूर मौजूद एक Star System | और हमारे यान ने धरती से चलना सुरु किया, जब हम इसके पीछे मौजूद Space को फैलाये है इसके आगे मौजूद Space को सिकोड़े तो हमारा यान बेहद ही कम समय में अपने मंजिल तक पहुंच गया |

Examples of Warp Drive Technology

Let us try to understand this through a famous example from MIT. Suppose our space is a Slinky, on one side of which is our Earth and on the other side is a star system many light years away. And our spacecraft started moving from the Earth, when we expanded the space behind it and shrank the space in front of it, our spacecraft reached its destination in a very short time

Warp Drive Technology also works in exactly the same way. The special thing here is that we have expanded only the space behind our vehicle and compressed the space in front of it. But our spacecraft itself will remain safe in a bubble and there will be no change in the space inside this bubble.

The thing to be noted here is that our vehicle is not moving at the speed of light or faster than that, rather we have defeated the speed of light only by expanding and compressing the space in front and behind our vehicle. This Warp Drive Technology has been specially used in the famous Scifi Movies – Star Trek and Star Wars, through which Starships were able to travel from one Star System to another Star System and galaxies thousands of times faster than the speed of light.
