Do you consider yourself to be a science buff? If you do, then you’ll know that science doesn’t involve proving what works. It involves proving what doesn’t work. Known as the scientific method, we use it everyday. You start with a question like, “Will drinking milk make me sick?” Well, there’s only one way to find out. We create a hypothesis and test it. Did it make you sick? Let’s test another kind of milk. Scientists do this all the time. Some questions, however, are still elusive. Either they can’t be tested (metaphysical), or more testing needs to be done. These are 25 Simple Questions Science Still Can’t Answer.
Can we stop aging?
Actually…what is aging? And why do we do it? The general consensus is that aging involves the gradual molecular damage building up over time. (Although, even that is up for debate.) Regardless of the cause though, the million dollar question is – can we stop it?
Is biology universal?
So while physics and chemistry appear to be the same across the universe, scientists still aren’t sure whether the rules of biology would extend to lifeforms on other planets. For example, would those lifeforms be based on the same molecules as us? Or might they be based on something totally different…like silicon?
Is there purpose or meaning behind the universe?
For most of history, science has wisely left this question to the realms of theology and philosophy.
Can we support the Earth's population in the next century?
This question has arisen several times before in history, notably prior to the Industrial Revolution. Many politicians and analysts thought that it would be impossible to support so many people. Of course, the railroad, electricity, and industry proved them wrong. The question has come back to haunt us, though. Now can we find another solution?
What is music, and why do we have it?
Why should we find pleasure in listening to various combinations of vibrations at differing frequencies? Why did people develop this ability to create it? And what purpose does it serve? One hypothesis is that it aids with sexual reproduction, much like a peacocks tail. But as of yet, this is only a hypothesis, not a theory.
