3 Astronomical Unsolved Problems - 01/01/06 09:56 PM
The Constant acceleration of Pioneer 10
Pioneer 10-Launched in 1972, is still moving out
into deep Space. The problem is that nobody knows why it has speeded up.
Scientists have ruled out a fuel leak, software error, or solar wind. Its minute, but constant acceleration, has been causing Cosmologists problems as to what might be causing it.
Microwave background temperature appears the same everywhere?
Temperature measurements on our Universe appear to be uniform. But the two edges of our Universe are measured to be at least 28 billion light years apart. But since our universe is only 14 billion years old, how could heat radiation have evened out the hot and cold spots created in the big bang?. Leaving the thermal equilibrium as seen today, when the speed of light is supposed to be constant?
Could there be a Planet X?
Reasoning is as follows.
Travelling out beyond Pluto, you reach the Kuiper Belt. A region full of rocks and ice. Once you have passed thru the Kuiper Belt there is nothing. The only explanation seems to be that a large Planet has swept the area clean. If Planet X is there, it can only be detected visually,... but not so far.
