"dark energy plus dark matter constitute 95.1% of total mass–energy content." (of the universe)
"The name refers to the fact that it does not emit or interact with observable electromagnetic radiation, such as light, and is thus invisible to the
entire electromagnetic spectrum."
"Many experiments to detect proposed dark matter particles through non-gravitational means are under way; however, no dark matter particle has been
"Although the existence of dark matter is generally accepted by most of the astronomical community,"
"Study reveals that 400 stars within 13000 ly of sun all matched expected ratios of having regular matter, no dark matter there'"
"Since its discovery in the 1930s
, the material has become crucial for galaxy-formation theories,"
"One particular type of supernova known as Type Ia has the useful property of exploding with a fairly uniform brightness. This means they can be used
as “standard candles” to determine their distance. Basically you can observe its apparent brightness and compare it to its actual brightness to
get a distance. Observation of some of the most distant supernovae at the time led to the Nobel-winning discovery of dark energy.
But recently there’s been evidence that there is more variation within Type Ia supernovae than originally thought, including a dimmer variation
known as Type Iax. This means the uncertainty in the actual brightness of Type Ia supernovae might be greater than we’ve been using"
Yes they created the theory of dark energy in the 1930's based off the brightness of 2 distant supernovae. Thought they were too far away.
Remember this was 50 years before the invention of the internet and popularization of computers.
We're in 2017 using more advanced techniques. Not only is there no trace, we're finding there was no reason to have a commotion over the initial
