Age of the Universe in Hinduism

In Hinduism, the age of the universe is measured using enormous cosmic time units like kalpas and yugas. Current Hindu cosmology states that we are in the Kali Yuga of the 28th Mahayuga in Brahma’s 51st year. The scriptures estimate the universe’s present age at over 155 trillion years, much older than modern science’s estimate of 13.8 billion years.
