Alien spaceship wormhole gravitational waves detector

In summary, the article discusses energy requirements for creating a wormhole, and suggests that if a small wormhole is created with a minimal entrance area and length, then gravitational waves will be emitted as the wormhole closes.

Recently viewed video about wormholes that required negative energy to create it. Suppose hypothetical aliens have discovered this technology. Spaceship enters in first point and exit at second. To prevent spaceship destruction they might have technology to smooth gravitational waves on exit side, but first point hypothetically should have them. Can we use LIGO to detect gravitational waves left from closing wormhole less then 1 mile in diameter? ;))

NASA working currently on wrap drive. When starship moves this drive also should create gravitational waves

You'd have to find a solution to Einstein's field equations describing your opening and closing wormhole, then derive whether it emits gravitational radiation (by no means something you can just blithely assume). Ditto the warp drive. Then you have to determine whether the amplitude and frequency of any emissions falls in the range LIGO could detect.

Good luck! You're going to need a pretty big computer.

It depends on the energy of the wormholes, @Dinarchik. I don't know about the current sensitivity, but in the early days of LIGO coalescing binary black hole systems with individual masses of 30  M⊙ could be detected out to 1.3 Gpc. I'd expect LIGO could detect your small wormholes if they were much closer in, but presumably there would be a burst of EM radiation that would be also easily detected.

How far away are you suggesting these alien spaceships would be popping in and out of warp?

In this article https://arxiv.org/pdf/0809.0907v1.pdf Author analyze energy density of wormhole equal density of string. Black holes don't have such density in event horizon - only if it minimal size black hole made entirely from strings. Maybe real black hole interior core going to have this minimal size.
I did analyze math and looks like it not depends on Energy at all, but on area of entrance surface divided by length of wormhole. Means the more length device have to create wormhole the less energy it requires. Confusing.
But signature of gravitational wave of closing wormhole cannot be misinterpreted: it like black hole momentarily appears on this place. If regular gravitational waves should be smooth waves this one going to have sharp corners.

@Ibix: Did you move this post to Science Fiction and Fantasy?
No - only mentors can move threads. It's the right place for discussion of gravitational waves from alien drives, though, unless you can produce a better reference than one that doesn't even mention gravitational waves.
 

1. What is an "alien spaceship wormhole gravitational waves detector"?

An "alien spaceship wormhole gravitational waves detector" is a hypothetical device that is designed to detect and study gravitational waves, which are ripples in the fabric of space-time caused by the movement of massive objects. The term "alien spaceship" refers to the idea that this device could potentially detect signals from advanced extraterrestrial civilizations, and "wormhole" refers to the theoretical concept of a shortcut through space-time.

2. Is it possible to build such a detector?

Currently, there is no known technology that would allow us to build a device capable of detecting gravitational waves from alien spaceships or wormholes. However, scientists are constantly researching and developing new technologies, so it is not impossible that such a detector could be built in the future.

3. How would the detector work?

The exact workings of an "alien spaceship wormhole gravitational waves detector" are purely speculative at this point. However, it is likely that it would involve highly sensitive instruments that can detect tiny disturbances in space-time caused by gravitational waves. It may also utilize advanced communication technology to receive and analyze signals from distant sources.

4. What would be the significance of detecting gravitational waves from an alien spaceship or wormhole?

If such a detector were to exist and successfully detect signals from an alien spaceship or wormhole, it would have huge implications for our understanding of the universe. It would provide evidence of advanced extraterrestrial life and potentially open up new avenues for space exploration and communication.

5. Are there any current efforts to build an "alien spaceship wormhole gravitational waves detector"?

As of now, there are no known efforts to build such a detector. However, scientists and researchers are actively studying gravitational waves and looking for ways to detect them, which could potentially lead to the development of a device like this in the future.
