I thought they are going to divert it by placing a spacecraft near it so its gravity would change the orbit.

If there is a counter mass on the far end then they could move it further or closer depending on the load lifted and the position it reached to keep the CoG at the desired place right?

I knew about the common mathematical teaser with the excessive information trying to confuse you so I made this one up to see how many people will asume it is a teaser .

But you ARE cheating, the test explains clearly what you have to do. It doesn't say anything about writing. 205ms for the best time yet seems rather slow, do you register it locally or do you have some sort of internet lag?

Here is another problem: Say the bmw goes at 90mph and the vette goes at 30mph, the bmw is travelling from NY to Washington (204 miles), 1hour after the bmw departed, the vette starts from Washington to NY. What is the distance between the 2 cars 1 hour before they meet?

If antimatter has everything backwards why not gravity too? If it has negative gravity then it would repel itself into single particles spread rather uniformly in the space. You would say then why don't we detect small annihilations when traveling in space? Maybe all the massive objects in the solar system overpowered their negative gravity and annihilated them long ago, maybe there isn't much antimatter left inside the galaxies either. Is it possible to detect such properties of the antimatter inside a lab? Have anyone tried this yet?

Your calculations are wrong with 1.7 you could stay at 59.5°. And even the best supercars barely reach friction of 1.15 even having aero downforce to help them: http://www.modernracer.com/features/worldsfastestcars4.html

Why do you think there is anyone watching us at all? We are on an insignificant system and only started broadcasting radio waves recently so a very small number of stars could have any evidence that there is someone here.

Ofcourse you can climb angles even above 90° but not walking. You can't walk at more than 30°.

At ground level the steepest you can climb is about 30°. Even if you build it at the pole the centrifugal force will not be strong enough to help you climb before you reach the 30°. The gravity won't be much less either so I think you will lose grip to go any further at about 30-35°. This is me at the monza oval at ~30° banking:

I like to think about the universe like this: You cannot be at the edge of the matter going away from the center of the big bang at light speed because you can always point a beam of light over that edge. If the laws of physics are the same everywhere and there is no special place in the universe like a place where the big bang happened then this implies that the big bang happened everywhere at the same time. If there is something going away from something at light speed for everything in the universe then the universe is infinite. For every observer in the universe, the space gets progressively distorted the further away from him. Close to the 13.7 billion light years distance everything is going away from the observer at nearly light speed so it is nearly flat. So for every observer, the universe is a sphere with 13.7 billion light years radius where everything near the edges gets infinitely flat and infinitely dense and with infinitely slowed time so you can take this as the limit of the universe although the universe remains infinite nevertheless. Are my thoughts correct? As a speculation: if there is infinite mass and density at the edges of the universe wouldn't that be the cause for the accelerating expansion since the gravity of everything on the edge will pull everything inside the sphere and eventually everything will end up on the edges. But everything is also always in the center of the sphere so the pull is always cancelled out... Thinking about this can make you crazy.
