Dr. Gerald Schroeder published an article in Aish.com about the age of the Universe and the Jewish bible:
So the only data I use as far as Biblical commentary goes is ancient commentary. That means the text of the Bible itself (3300 years ago), the translation of the Torah into Aramaic by Onkelos (100 CE), the Talmud (redacted about the year 500 CE), and the three major Torah commentators. There are many, many commentators, but at the top of the mountain there are three, accepted by all: Rashi (11th century France), who brings the straight understanding of the text, Maimonides (12th century Egypt), who handles the philosophical concepts, and then Nachmanides (13th century Spain), the earliest of the Kabbalists.
Then he make this claim:
The calculations come out to be as follows:
• The first of the Biblical days lasted 24 hours, viewed from the "beginning of time perspective." But the duration from our perspective was 8 billion years.
• The second day, from the Bible's perspective lasted 24 hours. From our perspective it lasted half of the previous day, 4 billion years.
• The third 24 hour day also included half of the previous day, 2 billion years.
• The fourth 24 hour day ― one billion years.
• The fifth 24 hour day ― one-half billion years.
• The sixth 24 hour day ― one-quarter billion years.
When you add up the Six Days, you get the age of the universe at 15 and 3/4 billion years. The same as modern cosmology. Is it by chance?
But there's more. The Bible goes out on a limb and tells you what happened on each of those days. Now you can take cosmology, paleontology, archaeology, and look at the history of the world, and see whether or not they match up day-by-day. And I'll give you a hint. They match up close enough to send chills up your spine.
Many Jewish websites make similar claims - that their scholars made biblical predictions in advance of modern science long ago. Is this true?
