Ninety five percent of the universe yet to be discovered
The latest research has it that some form of unseen energy, of unknown nature, makes up about two-thirds of that total “energy density”. Of the stuff with mass, which thus counts as matter, inscrutable “dark matter” constitutes another quarter of the universe’s contents. What is left is what humanity perceives as normal matter. But it is far from normal. Every atom of Earth, every star dotting the heavenly vault, every bit of dust between and beyond: together they account for less than 5% of the universe’s recipe.
In an era when so much science seems understood, all this uncertainty might appear to be an embarrassment. Not so. Any physicist would tell you it is an opportunity, a frontier. After all, from his point of view, there remains 95% of the universe—a quintessential part, it might be said—yet to be discovered.
And this is only our universe
