What if I throw a rock while moving at the speed of light?

"As an enthusiast of science and physics, I've always been fascinated by the fundamental laws and principles that govern our universe. One concept that I've encountered in my readings and discussions is the speed of light and the theory of relativity developed by Albert Einstein.

One aspect of this theory has left me somewhat puzzled, and I'm hoping you can shed some light on it. The question that has been on my mind is: "If I were to move at the speed of light and throw an object, such as a stone, ahead of me, would that object exceed the speed of light?" - Travis


Relativity Before Einstein


Thanks for the question Trent and an interesting one at that.

To answer your question in no uncertain terms...

No, the stone would not exceed the speed of light.

In our universe, nothing can travel faster than the speed of light, which is approximately 299,792,458 metres per second. This concept is one of the fundamental principles of physics, as explained by Albert Einstein's theory of relativity.

Even if you were moving at nearly the speed of light and threw the stone ahead of you, its velocity would still be less than the speed of light when observed by someone outside your motion. This is because as you approach the speed of light, the energy required to further accelerate an object increases significantly, making it increasingly difficult to make it go any faster. This principle ensures that nothing can surpass the cosmic speed limit of light.



The section where we explain the above to 5-year-olds (and Flat Earthers).

Imagine you have a super-fast spaceship, and you're inside it, traveling really, really fast, almost as fast as light itself. Now, you're holding a stone, and you throw it out of your spaceship.

Even though you and your spaceship are super fast, the stone you threw isn't faster than the fastest thing in the universe, which is light. It's like a cosmic rule that nothing can be faster than light. So, no matter how fast you throw the stone from your fast spaceship, it will never, ever be faster than light.

Light is like a superhero speedster in the universe, and nothing can beat its super speed, not even your spaceship or the stone you threw.


You’ve come this far…
Why not venture a little further into A.S.S. - our exclusive Australian Space Society. 

And keep thrusting Australia into the deep unknown…
