If you’re against space exploration-bla blah blah part 2

Let’s continue this shit

space is fake

Earth is fucked beyond repair thanks to fat Americans driving ridiculously sized pickup trucks around, hence our need to find a new planet (Mars) to live on.

Nice image.

Beautiful isn't it?

Continuing the shit. Normie stuff you get from investing in space exploration:
> satellites
> maybe supersonic travel via low Earth orbit
> better engineering methods, materials, ...
> more knowledge that can be transferred into other activities
> jobs in research, manufacturing, development...
> improvements in military stuff

Hi jews!

It is pretty expensive considering it relies on pure imagination. Might as well pay for porn.

Then our best bet would be to try and understand the motives behind such a rule and possibly fulfill them if applicable, and after that judge for a second time if it’s truly the right thing to do. I would guess at being fit for an already-existing galactic society that we aren’t aware of (or fully, or widely) is a good reason for this. In reality, we don’t have much excuse past this because of all the UFO rumors, and alien conspiracies that exist in the public awareness, whether we choose to believe them or not. This exists in addition to all the efforts that are being made that seem, at least on the surface level, to ready us for such a transition. Your proposal doesn’t sound too ridiculous, and given Fermi’s paradox the justification for space exploration outside of your proposal does seem insensitive. I still think there is merit in at least preparing ourselves for space exploration, and in the worst case scenario we should have both the ability and will power to do it for our own sake. What’s that saying? God helps those who help themselves? I think that’s fair.

Physics kiddies who just learned conservation of energy have to forget all that shit when it comes to rockets. Because a rocket expends energy just to maintain it's position, much less to accelerate. Therefore basic energy calculations don't get you anywhere. What matters with a rocket is Impulse:

There are also design considerations. It's counter-intuitive, but you also want the center of thrust to be far below the center of mass. It seems like you would want the opposite, for the engines to be "pulling" the mass up through the sky. But such a rocket would be horrifically unstable, you want the thrust pushing the mass in front of it.

Finally, the rocket burns off mass over time, so to figure out it's acceleration you need to consider the mass it loses as the rocket burns. This is called the "rocket problem" in physics, it results in a differential equation.
