Oh, I know about Cherenkov radiation. I guess I will still look it up for more information, but I knew what Cherenkov radiation was for a while now. Thanks though.

Thanks for the input, Drakkith. With how close the speed you said, the 99.97 percent of c one; if I am not mistaking it to be the speed of light in a partial vacuum; it makes sense to round it to the speed of light in a perfect vacuum. Come to think of it, breaking the speed of light in a...

As we all know, light itself is the fastest thing in the universe, and the cosmic speed limit, basically. That said, it is said to go at 299,792,458 meters per second in a vacuum. That is pretty fast. However, I have a question I want to ask... Does light really go that fast in a vacuum? I ask...

That is why this is more so theoretical on the massless object part. Reaching zero mass in real life would be as impossible as reaching infinite relativistic mass, would it not?

Understood. I am sorry if I irritated you.

You actually need something that big to change its direction? Why?

Basically, it is how hard you have to push or pull the object with a force to change its direction. We'd be using centripetal force in that case. If you want more, let's make the radius 0.0001 meters. We should already know the mass and velocity here. Anything else you would need?

I see. I think I know what you mean. So with that logic, would a massless object be easier to change direction than the canoe?

What would you need to do so?

Ah, well, what I meant would be, how hard would it be to use centripetal force to change the direction of a massless object?

I am assuming centripetal force is not going to apply here?

So how easily does an object change direction without mass, may I ask? If usually? Should I describe what kind of energy is in this kind of situation?

A fault on my part. I just edited the original post on this topic.

This is a theoretical question, not based on anything in real life, only theory. A thought experiment. Now, say that something does not have any inertia, or mass, whichever term you want to use is fine. Now, if a force were exerted on this theoretical object, how fast would it accelerate? Also...

Okay, I think I get it now. Just wanted to make sure. Thanks.
