How do scientists know the Earth is 93 million miles away? Why not 87 or 95...How can they be so sure, so exact? I understand you can measure some things by trigonometry and such like, anyone any idea?
As an aside, when you see the sun, you are not seeing it as it is now, but how it was around eight minutes before, because of the speed of light it takes just over eight minutes to be seen on earth. If you think about it, it might have gone out and you wouldn't even know for eight minutes...:)
Why doesn't the Beetham tower on Deansgate not fall over with all that weight on one side and a narrow base? What a stupid design, surely it should be the other way round?
Post your own musings up......, a fellow smartarse Bluemooner might come up with the answer.
