The Eternal journey of Voyagers into the Space

- November 28, 2025

If you have seen Interstellar, chances are really high that you must have liked it. But have you ever paused and focused on the word Interstellar itself?

In other words, he travelled interstellar. Yes, it was just a movie. Umm not just a movie for me personally but nvm. But here is the part that still blows my mind. Humans have actually made two real spacecraft that travelled interstellar for real. Not CGI, not fiction, not theory.

To answer this, we have to travel back in time, to when planets were young. I will be explaining in the form of questions and a bit of storytelling, do tell me if you find this bit more easy to understand. A Young Planet Is Born Imagine the early Solar System. It was not calm and quiet like today. It was a turbulent scene. Dust swirled around a newly formed Sun. Rocks constantly collided. Gas clouds crashed into each other. Temperatures were extreme, hot enough to melt rock. In this violent environment, tiny particles of dust began sticking together. Over time, these grew into larger clumps, often called planetesimals. At first, these young worlds were oddly shaped. They were uneven, jagged, and far from the smooth planets we see today. So what changed? Gravity The Shape Maker The answ...
