The death that creates life

When you look up at the night sky and admire the beautiful stars, have you ever wondered whether they have a lifespan? How long will they continue to shine? And perhaps more intriguingly, what happens when they die?

Gravity gave birth to the stars

Have you ever wondered how stars are formed? Why do they twinkle? There are an estimated 100 to 400 billion stars in our galaxy alone, and some are thousands of times larger than our Sun!

Let’s travel back in time

Have you ever wondered whether we could travel back in time? In the Special Relativity series, we learned that travelling close to the speed of light can, in a sense, allow you to travel into the future through time dilation. But what about travelling into the past?

Every planet wants to become a sphere

Have you ever wondered why the Earth is round? Why are almost everything in space—planets and stars—round as well? Why isn’t the Earth flat? And if the Earth is round, why don’t people at the “bottom” fall off?

Let’s try going faster

Have you ever wondered, in this vast universe, whether anything can travel faster than the speed of light? In Part 1, we discussed that nothing can travel faster than light. So the universe’s ultimate speed limit is the speed of light… right? Maybe not.

Moving makes you look shorter

Have you ever wondered if the length or size of an object can change according to its speed or the observer’s speed? Sounds ridiculous, right? Apparently, motion not only affects time, it also affects how lengths are measured.

The faster you move through space, the slower you move through time.

Have you ever wondered is time travel really possible, like in the movies? Surprisingly, according to Albert Einstein and his theory of Special Relativity, travelling into the future may actually be possible. One of the strangest consequences of special relativity is something known as time dilation.

The universe’s speed limit

Have you ever wondered what inspired Albert Einstein to develop one of the most revolutionary theories in physics? In this series, we will explore the foundations of Special Relativity — and everything begins with one fundamental thing: light.

Curiosity kills the cat

Have you ever wondered how curiosity can actually kill a cat? It’s not just a saying—it’s also tied to one of the most famous thought experiments: Schrödinger’s Cat, proposed by physicist Erwin Schrödinger.
