Can Flying Ships Defy Inertia and Make Instant 90-Degree Turns?

[Secan]

I haven't gone to movie theaters in 6 months. So I have to be content with online movies, and reading sci fi models, and maybe writing a short story or two.

If a flying ship could travel thousands of miles per second, it can't suddenly turn 90 degrees because of inertia, the occupants would be flattened or juiced on the wall.

So what kind of physics world in which inertia can be canceled?

Also about General Relativity. It is just a model. Doesn't it allow 90 degree instantaneous turn? If not, and the world building needs to have flying ships that can cancel Inertia. Does it mean General Relativity in the story needs to be falsified? or can it be in addition to General Relativity?

You can reduce the problem to general case. No travel speed is necessary. Both you observer on the ground and the ship passengers for whom the ship is at rest observe flattening and juicing by change of course. In general we can say acceleration, more precisely acceleration in inertial frame of reference (IFR) cause such tragedies.

GR says acceleration and gravity have some similar features. Rocket pilots experience tens of G in launching. Acceleration of rocket by firing engine causes the same effect as the Earth gravity of 1G increases to 10G.

GR says nothing about cancel of inertia. I am afraid no theory would not reply in future also.

I don't want it to be relativistic speed. Just ship traveling in the atmosphere. Our US Navy pilots and aircraft carrier personnel have witnessed these things where they travel thousands of miles per second then instantly turn 90 degrees and caught at radar too.

So science fiction must at least include these behavior too to be intriguing and modern.

What would it take to cancel Inertia? What causes Inertia?

In my story. They are piloted by Borgs.

Relativity theory covers all range of speeds. Science fiction may cover any fictious theories and stories.

For General Relativity to be true. It means Space and Time must really be flexible. Not just in the math, but in actuality. This means the world is not some bolt and nut.

And because reality is malleable. General Relativity could be only an effective theory. If you use the full theory, and initiate some kind of symmetry breaking or unbreaking akin to electroweak symmetry breaking, then you could perhaps turn from the concept of gravity to being fictitious force to gravity becoming controllable?

Anyway. If you guys have time. Try to watch this Documentary called "The Phenomenon". https://www.imdb.com/title/tt13095604/ currently with 8.2 score in which US Senators and Presidents, the Navy and high ranging officials were involved in the phenomenon where after our nuclear development in the 1`940s. These flying ships began surveillance of our nuclear arsenals. The flying ships can instantaneously accelerate and turn 90 degree at incredible speed. Does this violate General Relativity. Isn't it inertia is part of General Relativity?

Some witnesses and contactees have come to the conclusion these are piloted by Borgs possessed by entities of other dimensions. Recall the movie Event Horizon where experimentals in portals enable the entry of the demons. So the contactees claim the Borgs did that once and got possessed by the entities.

Whatever they are doing in the nuclear arsenals are tactical. Is it to ensure we won't destroy our planet for our benefit or for them we don't know. Please watch it first before answering so you have some background.

The ideas in the documentary are far ranging and latest. Are there not science fiction writers who have already ideas what to write connected to them?

Whatever, my short story will revolve around the debates among scientists how the technology can be compatible with General Relativity. This after the whole world learned of their existence after the world is saved from annihilation by a president who pressed the nuclear buttons with his supporters. So I need to know if there the better theory has modes where Inertia can be canceled and gravity controllable.. perhaps by going from symmetric General Relativity to an unsymmetric theory, something like it.

Is this thread about science fiction? Or is it about UFO conspiracy theories? Or is it about personal theories?

 

[DaveC426913]

These concepts are independent.
Relativity has nothing to do with high-acceleration maneuvers.

When you ultra high acceleration in films, it is because it is fiction.
When you see ultra high acceleration in UFO reports, it is because of poor observing conditions leading to premature and unwarranted conclusions.BTW, in Star Trek, they use "inertial compensators" - which is techno-babble, but it is generally assumed that it is a specific application of the artificial gravity the ships already have to locally damp inertial forces.

Science fiction inspired by reported events. Our science fiction is getting so boring we need more ideas and sensible contents.

 

[Jarvis323]

The type of apparent high acceleration/high speed events that people have reportedly witnessed, can be speculatively attributed to worm holes or warp drives, both of which are theoretically possible according to (and based on) general relativity. In sci-fi, theoretically possible, but speculative technologies are no problem. I don't know what either would theoretically look like to an observer, but note that warp drive and wormhole travel work by changing the travel distance between the source and destination (shrinking the space, or taking a shortcut) rather than cancelling inertia, or allowing extreme acceleration, or anything like that.

Currently, one of the best explanations for those military UFO sightings/radar readings is a sort of holographic technology that has been declassified and gone mainstream, which is used to fool radar systems and produce deceptive visual illusions.

Science fiction inspired by reported events.

If you mean the ones @Jarvis323 is referring to, discussion of any possible scientific basis for such events (assuming they actually occurred, which is by no means established) does not belong in this subforum. Science fiction is one thing. Discussion of alleged actual events and possible scientific explanations for them is another. And the latter type of discussion needs to be based on more than uninformed speculation based on a mistaken understanding of General Relativity.

The type of apparent high acceleration/high speed events that people have reportedly witnessed, can be speculatively attributed to worm holes or warp drives, both of which are theoretically possible according to (and based on) general relativity.

"Theoretically possible" in this case is very, very far from "should actually be expected to be observed".

Since this thread is not about science fiction but is uninformed speculation about science, it is now closed.
