Could dark energy be used as an antigravity device?

AI Thread Summary
Dark energy, which is believed to have a repulsive effect opposite to gravity, raises the question of whether it could be concentrated to create an antigravity field. However, the feasibility of this concept is questionable, as dark energy's nature remains largely undefined. Current understanding suggests that dark energy is an intrinsic property of space-time, complicating the idea of manipulating it. The discussion highlights the uncertainty surrounding dark energy and its potential applications. Ultimately, the possibility of using dark energy as an antigravity device remains speculative.

If you were to concentrate enough of it in one place, could it generate an antigravity field, similar to the hypothetical 'negative matter'? Only it is proven to exist. I am wondering this because it obviously seems to have some kind of repulsive effect that is exactly the opposite of gravity. Though it may not be feasible, could it work?

We don't even know what dark energy is definitively so whether or not you can do something with it is a moot point. Our best understanding of dark energy is that it is a property of space (space-time) itself, so to say that you can get some dark energy and "put it" some place doesn't make much sense.

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
