what do you think

Just out of curiosity if...IF There were NASA type Jedi I will ask the following questions.

If for some reason a rock... meteor...ship...planet ever knocked earth off its axis would we feel it as in where I'm sitting do I fall over? Does it knock us down? What do u think happens. I await your responses eagerly! Thanks in advance

Well if all the scientific theories about space and how planets and space in general works are accurate, I'd imagine that if a huge planet or asteroid collided with us first you'd see a fire in the sky from it entering the atmosphere, it'd rain hell on Earth.

This event would be so huge that even on the opposite side of the Earth, the sky could still appear crazy as you'd see bits and pieces flying off in different directions enterining the opposite side's field of view. Upon impact I'd imagine it could be a like having a global earthquake, imagine the force that would affect the waters alone, structures and mountains.

Something smaller, would have just a similar but less intense effect. But you know, I've seen a lot of things recently that really make me question NASA as a whole, I'm not a flat earther but damn some things are very convincing and there's a lot of questonable things to what we are told.

Any event large enough to change Earth's axis would undoubtedly kill us all immediately, but for the sake of this hypothetical situation, it wouldn't change the effect of gravity in a localized sense. We might be knocked over by the tremor the impact would cause, but once that settled, the long term effect would be a change of the seasons. It would effect how long Summer and Winter would be and weather patterns would change. The magnetic poles could possible flip as well.

Carlos ...

It is an interesting question to ponder. Earthquakes actually can shift the Earth's axis slightly, as well as other meteorological events -- including asteroid impacts. Most of these are small enough that the shift is very slight, and so, unless one actually is where the event is localised (the epicentre of the earthquake, the impact of the rock) one doesn't really notice much of anything apart from possibly a tremor. That is still taking into account a lot of force ...

If a major event took place that would actually make a vast difference in the planet's relative motion, then it is quite likely that we would not survive it. Consider, if you would, whiplash. One doesn't have to be going very fast in the car to get quite a jolt if something - a collision, say - causes an abrupt change in relative motion.

On the scale of something that would do that to the Earth, we are talking about multiples of thousands of times that sort of "jolt". For each of us, that would be like getting flung about at around 1000 miles per hour. Quite enough to do some really nasty injury. That would just be the 'shock', barring actually being at the point of impact, or whatever caused the effect.

Let's just hope that doesn't happen.

Then if it knocked us off axis I'm sure air, water, magnetic curents would change and we might feel or see it, experience it with our electronics and modern technology. Time of day and night might gradually change as well if we get further from sun at one end, making things cooler and changing climate, then getting hotter and crazy if we end up closer than normal.

I was preparing a lengthy post showing you guys some of the math, but... let's say it gets sufficiently complicated to where one would have to either introduce or presuppose entire formalisms, all to reach a conclusion that can be summarised in but a sentence.
The kind of impact that would be enough to change the Earth's axis so much that it would not fall well into its natural little oscillations is also an impact that would likely change the Earth's orbit to where the seasons got even more different in length than they already are and in the worst of cases could make the planet too hot for most of its current inhabitants for a good portion of the shorter season. Even if we discount the atmosphere burning up because of the impact and other such cataclysmic consequences, an event like that would pretty much be the end of Earth as we know it. Of course some sort of planetoid impact is not the only way the rotation axis could be shifted, but if the question is specifically about the results of a collision of sorts, that's my answer.

On another note...

I'm by no means an apologist for NASA. Much though I might respect their overall achievement in technology innovation and engineering, and even public science communication, when you see them endorse nonsense like the Hyperloop, you cannot help but question whether there might be better warming furnaces to burn tax money in. That being said, Pretty much everyone who had a major contribution to classical mechanics or thermodynamics was dead well before NASA was established.
So, in that spirit, if you don't mind, what exactly are these "some convincing things" that do not quite push you to the flat Earth model yet? I would encourage everybody of course to question everything until a satisfactory explanation and/or demonstration is available to them, and to some extent even afterward. So in the hope to perhaps try my own understanding or improve someone else's, what are some of those questionable things that you are being told?

The remark that we would not survive such an incident is made a few times , lets assume a few of us did , the ones with the best survival techniques will maybe be ok for the first few weeks but very soon they will find that food is not as available anymore as they were used to , due to the shock and the changing seasons it might very well be that plants either dont grow anymore and that the whole planet surface is scorched or frozen which will make days of the weeks i said , either way not a nice way to go from there , i hope i dont survive such an event really i see no Bliss in dying of hunger or burns or freezing to death , but thats just my little gloomy view :dry:

A rapid acceleration/s of the planet? No physicist but I'll take a stab at a fun topic. Earth has a pretty special set of circumstances which has seen life grow to such diversity, and we are alive only because of it. If that were to change too much it could change things in a big way for life as we know it. So if we ignore the reasons why such a change might happen, then the next question would be how much of a change happens. If the Earth spun too much faster then it might throw off anything not bolted down into space, or if it slowed down too much the extended exposure to the Sun during week long 'days' might dry moisture out of vegetation. As for the immediate impact of a sudden acceleration in some direction of spin, I think you would feel it yes, and things like the atmosphere and bodies of water would also react to the change in momentum of things.

It has already shifted a little according to this https://www.youtube.com/watch?v=_HZ_Dvkxi-8
