WebFeb. 16, 2024 — A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a... Websource. There were several essential stages to the discovery of dark energy. First, we must travel to 17th century England, where Sir Isaac Newton’s law of gravity proved there is a gravitational force between all objects of mass.. Fast-forward to the early 20th century when Albert Einstein took Newton’s law further with his theory of general relativity.
