Flat Earth General / Re: Rosetta's Philae probe makes historic landing on comet

First of all, Scepti, if you've "grasped" anything about what we've been telling you about space travel, you would know that reaching a speed of 51,000 miles per hour is not actually that great of a feat, and not to mention that the majority of that burn happened barely into medium Earth orbit. The spacecraft itself did not get itself to those speeds.Oh ok, then what made the space craft get to these speeds if it didn't use any fuel. gravity pulling? what did it do? just sling shot around planets and whizz into space?
Tell me oh great one.
I hope you are aware that this speed is relative to the Sun, not the Earth. Speed is relative, always. You need to compare it to something. If you are travelling in a plane, your speed relative to the plane is 0mph because you are sitting, but your speed relative to the Earth is 700mph.
The speed at which the Earth rotates the Sun is about 66600mph. The probe is now cruising towards Pluto at a speed much lower than this.
Hey, did you also know that the speed at which a rocket outside the atmosphere accelerates is exponential? That is because without the drag of the atmosphere and the light rocket (because it has burnt most of its fuel and jettisoned the lower stages), the thrust to weight ratio becomes extremely big! That means it requires little time and little fuel to accelerate it to an escape velocity with those powerful engines.
I find it funny that you dare trash talk and bash things you don't even understand.
Typical "I am not able to comprehend it therefore it's all fake and I'll choose the way that seems more plausible to me because I have no idea what the hell I'm looking at".
