About science

In our daily life we are faced with observations for which we have no valid explanation. There are questions for which we don’t know any valid answer.

For some of these questions we know that we cannot know the answer. “Does it all make sense?” is one of them. See The meaning of life.

Some of these questions have been unanswered at some time but got an answer as science evolved. For example, 500 years ago we had no valid answer to the question whether the Earth is flat or spheric, but today we can validly say that we know the answer to this question.

And then a lot of questions are kind of work in progress: What are the causes of cancer or asthma? Is climate change so urgent that it requires actions that endanger economic stability? How can we satisfy the needs for water, food, education of a growing human population? How can we manage to live on this planet in sustainable peace?

These questions are the field of science.


The art of managing human knowledge.

scientific method

A set of recognized methodologies used to answer questions formulated as a theories.

scientific evidence

Evidence that confirms (or counters) a theory in accordance with scientific method.

scientific community

A world-wide network of scientists interacting in diverse ways in accordance with scientific method.


The practice or principle of basing opinions and actions on reason and knowledge rather than on religious belief or emotional response. Believing that science and human reason can answer our spiritual longing for seeing God and understanding his Good News.

Intermezzo: Watch Pumba and Timon talking about the stars.

Pumbaa: Timon, ever wonder what those sparkly dots are up there?
Timon: Pumbaa, I don’t wonder; I know.
Pumbaa: Oh. What are they?
Timon: They’re fireflies. Fireflies that, uh… got stuck up on that big bluish-black thing.
Pumbaa: Oh, gee. I always thought they were balls of gas burning billions of miles away.
Timon: Pumbaa, with you, everything’s gas.

“I don’t trust in science”

I disagree with people who say “I don’t trust in science”.

I agree that we should not blindly trust in science. Indeed scientific evidence does not mean that something is “definitively true” because science is just a product of human civilisation, and it is limited to the visible world. And indeed pseudo-scientific methods can be (and are being) abused by corporations who want to present some theory as if it was scientific evidence.

But don’t throw out the baby with the bathwater. God created humans with a brain, senses and intellectual capacities. He wants us to observe and analyze the visible world. He wants us to give a name to everything. Refusing to accept scientific evidence as a more trustworthy tool than for example a Holy Scripture is a form of superstition and leads to unrealistic results.

“It is better to take refuge in the Lord than to trust in humans.” (Ps 118:8)

Does science push back God to his ramparts?

Some people say that science “pushes back God to his ramparts”, constantly gaining ground as our technologies evolve. This statement implies that the Universe would consist of two “territories”, a visible “human world” and an invisible Kingdom of God. Christians don’t believe this. Christians believe that the Kingdom of God penetrates the visible world. They are not separate territories.

This expression is based on a correct observation: certain questions have moved during human history from the invisible to the visible world. Two thousand years ago humanity did not know about bacteria, viruses, evolution, atoms and such things. We did not know whether Earth is a sphere or not. In two thousand years humanity will probably know much more than today, and humans will be surprised when learning from historic sources that we didn’t know these things.
