Is it true that most of the both the mass and energy in the universe may take forms that you are unable to detect directly?

Yes, that's quite true! For more information, read sources such as Wikipedia on "dark matter" and "dark energy". Current estimates are that something around 68% of the mass-energy in the Universe is in the form of dark energy; 27% is in the form of dark matter; and about 5% matter of known types. Nobody really knows much about "dark energy" or "dark matter" - only that they exist.

How can people view black holes?
Currently we are unable to view black holes directly. We can only detect them indirectly by their effects on the movement of nearby objects and by X-rays emitted from superheated matter falling into them.

If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.

Your computer is unable to detect pen drive?
There are several reasons why a computer is unable to detect a pen drive. One common reason is that the computer does now know what drive letter to assign to the memory stick. One quick fix is to change the drive letter in the administrative tools of the control panel.
What is bigger than the sun?
The universe is an irregular blob of matter and energy expanding in three dimensions over time. As the universe is defined to include all matter and energy, there is no matter nor energy (and thus nothing to measure) 'beyond' it. If there were an unknown 'something' past the known universe, it would be a part of the universe (even if unknown/undiscovered).There are theories of 'alternative' universes existing in distinct time regions (in which the expansions and changes in the universe proceeded differently than the one in which we exist). The term 'multiverse' has come to encompass multiple universes, and could be considered 'bigger' than our one universe in the way a crowd of multiple people is bigger than one person in the crowd. However, we are as yet unable to directly observe the existence of alternative time-space continuums; in terms of the person/crowd analogy, we are like one person in the crowd who is unable to see, hear, smell, taste, touch nor sense in any way anything outside of ourselves (not other persons, not the floor, nor walls or objects in the room with us).
