Instead of Perceiving things per se (which, of course ,is not possible), we seem to thrust our preconceived notions under the guise of Science.
If we are determined if some thing is not there , it ought not to be there , physical evidence notwithstanding.

Best Epistemology is found in Jainism and Hinduism.
The star known as (deep breath) SDSS J102915+172927, in the constellation Leo, isn’t much to look at. It’s a bit smaller than the Sun and a bit hotter — but then, the same could be said for millions of other stars in the Milky Way. If not for a detailed census of the universe carried out over the past decade or so by the automated Sloan Digital Sky Survey (thus the SDSS in the star’s name), astronomers would probably never have noticed it….
When a team of European astronomers found the star in the Sloan’s massive database, however, they realized that the pattern of lines, and thus the mix of elements, was very different from the Sun’s. And when they used the powerful Very Large Telescope in Chile to take a closer look, they discovered just how unusual SDSS J102915+172927 is. For one thing, it’s almost certainly one of the oldest stars in the cosmos. The Sun has been around for about 4� billion years, but this star has been glowing for about 13 billion. Ancient stars are inevitably worth studying because they provide a glimpse into a time when the universe was young and still forming, and this, one, says Elisabetta Caffau, of the Center for Astronomy at the University of Heidelberg and the Paris Observatory, lead author of a study in the latest Nature, “was formed very shortly after the Big Bang,”
More to the point, however, is the startling fact that, according to conventional star-formation theory, the object people are now calling “Caffau’s star” shouldn’t exist at all. It’s very deficient in two elements — carbon and iron — that many theorists believe are critical components for normal stars to form in the first place. It’s also deficient in lithium, which is not essential for a star to take shape but ought to be present all the same. Wonders Hans-Gunter Ludwig, also at Heidelberg and Paris, and Caffau’s co-author: “Where has it [the lithium] gone?
To understand the mystery, you need just a little star science. The Big Bang created the first elements in the universe: lots of hydrogen, some helium and the tiniest soupcon of lithium. The very earliest stars — very massive, very hot and very fast-burning — were made of just these ingredients, nothing more. At the cores of these hot giants, nuclear reactions forged those three primordial elements into heavier ones, including carbon, oxygen, iron and more. When the giants exploded as supernovas, they spread the heavier elements out into the universe, where they were recycled into the second generation of stars — still mostly hydrogen and helium and a bit of lithium, but with a smattering of the new elements as well. Caffau’s should presumably be part of this second generation.
