You shouldn't. It's a good thing that you don't. That's why you need to get more information. If you only stick to one source, you will be lost. Pick up information and knowledge from many places and over time. That's better.
Allah didn't tell you these things. Allah supposedly told Mohammad, but can you be sure Mohammad hear everything correctly? Are you sure he didn't try to explain it in simplified terms for ancient people who didn't have science?
Can you imagine if you would travel in time back to that time and explain to anyone what a Black Hole in space is? Or how big the universe is? Or even how fractions, integrals, limits works in math? You would have to explain in a simple way. Perhaps Mohammad hear from Allah, but he had to make it simple and easy to understand and speak in figurative language? If Mohammad got scientific information from Allah, then why wasn't modern medicine invented until recently? It shouldn't have taken that long. All things considered, if God told any prophet anything, it would never be possible to understand it or take it literal. You have to read it and interpret it in the time it was made in.
