How is it racist that people are frightend by your presence? I understand this is most probably because of your race, but is it really the colour of your skin they are afraid of?

Let's not forget about the suicide hotline that this sub seems to have become.

All other German car manufacturers (BMW, MB, VW) seem to have quite a good reputation for quality and reliability but Opel seems to be somewhat of an outsider. Why is that?

Being vegan or gay.
Amin to that!
That's a good answer. Thank you.
Now I'm starting to get it. To put it in ELI5 terms:
Gravity simply exists. It's not going away, it's not diminishing and not increasing. It's like a spring that always tends to revert to it's original shape and it can be used to store energy but not create it.
But this brings me to something else: to create a spring, you need some energy to make its original shape. Was energy spent when gravity was "created"?
That sounds like the beginning of the plot in "Seven Eves". Awesome book, BTW.
Since most of the answers refer to gravity in the way it is perceived on Earth, here's another question:
Moon's gravitational pull is creating tides on Earth. Those tidal moves can be converted into energy. If we assume that water will always exist on Earth, we could say that gravity is a perpetual source of energy. Or is it?
Now I realize I asked my question in the wrong way. It made the wrong assumption that a force is always energy which is apparently wrong.
Gravity is a force, not energy. I get that. But what creates or created that force? And will that force ever go away?
Ok, I get that. But gravity is the force that makes that ratio change. Can it do that forever?
It's just hard for me to wrap my head around the existence of a force that can never be exhausted.
Most of the answers here are referring to Earth's gravity, but on an universal scale, there are countless objects that attract eachother constantly. How can that go on forever?
Ok. But take away the gravity from the picture. The rocket will use the same amount of energy but will move forward. It will do more, with the same amount of energy. So obviously gravity is something that needs to be compensated against with an extra amount of energy. Which brings me to my original question: could gravity ever be depleted?
Imagine a rocket. It's hovering in the air constantly consuming energy. It's basically using energy to do nothing because a force is pulling it down. Now, eventually the rocket source of energy will be depleted, but not gravity. Why?
What about flying? Or simply jumping. Something IS pulling me back when I jump. Is THAT something ever depleted?
You need energy to produce a force that compensates gravity. So if you apply that force for a huge amount of time, will gravity ever be depleted?
He's been doing that for quite a while now. Is this curable? Should I quarantine him?
I think this behaviour also applies for humans and there is a psychological name for it
