It really depends on what the difference in velocity is. The AC's are correct that if you are in the same orbit then you don't get anything. But I think what is being suggested is you would be in different but intersecting orbits. Think of Spiderman shooting a web onto a moving bus or train.

Something that is questionable is you would still need a way to kill your angular momentum otherwise as you wind yourself down to land your angular velocity will increase.

This is not a useful assertion, as you could say that about everything outside of pure mathematics.

That statement is logically incorrect. For if you were correct, then the above statement being outside of pure mathematics would be incorrect by its own assertion.

Plus the previous poster already granted the basic idea by saying:

This doesn't mean Newton's model isn't useful as long as you are aware of the assumptions and their limitations.

They already state why incorrectness matters - when you try to apply the model beyond the regime where it works.

Most people are well aware that there no absolutes in reality (certainly most scientists), so declaring commonly-used models to be "incorrect" or "disproven" does not advance the discussion - rather, it seems to more often be used in attempts to undermine the scientific case against the declarator's beliefs.

That doesn't mean the effort is invalid. To the contrary, it is more often a valid, scientific reason for rejecting the model in question. For example, a universal problem with climate modeling is the lack of empirical testing of these models. That in turn is a valid reason to reject using those models for extraordinary costly endeavors.

Scientific results exists even if you personally cannot confirm them. The point is that someone can confirm them, and does.

And the obvious rebuttal is a whole lot of people can confirm their invisible sky gods.

Can you personally confirm that electrons exist?

[...] Can you personally confirm that the Pope exists?

The answer is that yes, he can do that.

If people with private/corporate power didn't act like selfish dicks a lot of the time, maybe we wouldn't need as much government. And maybe we wouldn't be wiping out species and ecosystems at 100 to 1000x background extinction rate, and maybe we wouldn't be warming the climate and acidifying the oceans.

The USSR is a great example of why that "maybe" is a waste of consideration. A powerful government will take the environmental shortcuts too and it'll waive the regulations for itself.

And it's worth noting here that most developed world spending does nothing to help the environment. But it does help to fund cronies and hide government abuse and lack of enforcement of environmental regulation.

Finally, what's wrong with the environmental regulation of the past 40 years? Well, aside from being a job-killing morass that is. If you want to change environmental regulation, do so in a way that helps businesses rather than just encourages the ongoing shift of power to China and elsewhere.

Oh please, you're trying to imply that higher gas prices would somehow lead to a famine, which is ridiculous. Higher fuel prices would simply increase the cost of transport, which would result in some higher prices as that cost would be passed to the consumer. But they'd have more money to pay for it because their taxes could be reduced, since they wouldn't be subsidizing road costs through non-road-related taxes any more. (Of course, politicians never seem to reduce taxes like that, and once the original justification is gone for a tax they find another one, but that's another argument.)

Time is an illusion perpetrated by the manufacturers of space.
