The fact that the Hubble expansion rate of the Universe changes over time teaches us that the expanding Universe isn’t a constant phenomenon. But the “Hubble constant” itself is a misnomer. It has a value today that’s the same everywhere in the Universe, making it a constant in space, but it’s not a constant in time.
Q. Why does the Hubble constant change with time?
As the Universe ages, it expands; as it expands, the matter and radiation within it becomes less dense; as it becomes less dense, the expansion rate drops. The expansion rate, at any given time, determines the value of the Hubble constant.

Q. Why is the Hubble constant so important?
Hubble Constant. The Hubble Constant (Ho) is one of the most important numbers in cosmology because it is needed to estimate the size and age of the universe. This long-sought number indicates the rate at which the universe is expanding, from the primordial “Big Bang.”
Q. Why is Lord Krishna blue?
And in all these depictions, there’s one common link: the blue colour of his skin. The legends tell us that Lord Krishna had drunk poisoned milk given by a demon when he was a baby and that had caused the bluish tinge in his skin.

Q. Who was Kaliya?
Kaliya (IAST:Kāliya, Devanagari: कालिय), in Hindu traditions, was a venomous Nāga living in the Yamunā river, in Vṛndāvana.
