A very loud, low frequency sound detected in the oceans on multiple occasions. It's audio profile supposedly resembles that of a living creature, however due to the intensity, duration and frequency it would have to be much, much larger than any known animals that exist in the ocean.

Small observations can often mean large scale changes in the way we look at the universe. Little semantic things, like whether the Earth goes round the sun or the Sun goes round the Earth.
Small changes in the way we think can have profound impacts on the way we interact, manipulate and predict the world around us.
The Pioneer Anomaly is one such small observation. Since exiting the solar system (inner) and reaching the outer solar system, both the Pioneer 10 and Pioneer 11 spacecraft (launched in the 70's) have slowed down more than any single factor can account for. Like the diminishing of the mass of the Kilogram, it's a small effect that might have big implications about the way we look at the universe.

Now it's a curious thing, but the official Kilogram (the standard from which the measurement is derived) is losing mass.
Not much, very little in fact, but there's really no good explanation for it. Not yet. Perhaps some of the platinum/iridium used to make it have evaporated, although that doesn't sound like something that metal does. Not over as small a time as 100 years. Maybe it wasn't initially wasn't measured correctly, but I think that possibility would have been raised already and accounted for.
No, it seems that it's gradually losing weight. Minuscule amounts, the weight of a thumbprint, year after year.
Which, as it's so far unexplained, begs some speculation....
Perhaps it's not the mass of the Kilogram that's changing, but the attraction of the mass to the earth (gravity)?
Is it just the Kilogram that's changing, or are all things on earth and throughout the universe losing mass? Is it accelerating? Could it be the expansion of the universe is somehow manifest in the expansion of all things, the weakening of the bonds of matter and hence the universe?
It's a small thing, a small loss, but it raises some possibly big questions.

In some cultures, prayers are held to have an intrinsic meaning.
It is not the telling, or reciting of the prayer, the prayer exists on it's own, separate from the prayer (prayer, the recitation or written expression thereof, exists separately from the one who tells it...).
And this existence, the intrinsic existence of the prayer, influences the universe for the better, it can be replicated, multiplied and even mechanized.
The most notable examples are the Tibetans, with their branch of Buddhism that allows for prayer flags (prayers are carried from the flags by the winds), prayer wheels (spinning the wheel releases the prayer contained on both the outside and wound round the shaft of the wheel), there are other examples as well.
In Catholicism the saying of the rosaries would be equivalent, but only very roughly, for the church has not given sanction to machines to say rosaries, they must be said by the faithful, and the repetition of them, while apparently mechanical, is also contemplative and meditative. Whereas the blowing of flags by the wind, or spinning of unseen wheels by machines or people could not be said to be either.
I find this curious.
