    Speed
In summary, when an object reaches a speed close to the speed of light, it appears flatter to an observer. However, it cannot truly become 2D as it will always have a non-zero thickness. The measured length of the object can be made arbitrarily close to zero by increasing its speed, but it will never reach zero. Due to the object's rapid movement, the way it appears to the observer is complex and may appear rotated.

it is said that when something gets closer to the speed of light the flatter that thing will look when it pass the observer. i was wondering how flat that thing could look and could truly be 2D ?

Well, it can't get all the way to 0 thickness, so it is by definition 3D

You can make the measured length of an object arbitrarily close to zero by making it travel fast enough. It never reaches zero, though.

How it actually looks is a rather complicated topic for an object moving near the speed of light because the object moves a significant distance in the time it takes light to cross the object, so you see different parts of the object at different places along its line of travel. I gather it actually looks rotated, at least to a first approximation.

Related to How Thin Can Speed Make Things? 2D Possibilities

1. How does thinning affect the speed of an object?

Thinning can decrease the overall mass of an object, reducing its inertia and allowing it to move faster. Additionally, thinner objects have less air resistance, which can also contribute to increased speed.

2. Is there a limit to how thin an object can be to achieve increased speed?

Yes, there is a limit to how thin an object can be to achieve increased speed. Beyond a certain point, the object becomes too fragile and may break due to the force of its own movement. This limit varies depending on the material and shape of the object.

3. Can thinning only be applied to 2D objects for increased speed?

No, thinning can also be applied to 3D objects for increased speed. However, the effect may not be as significant as with 2D objects, as 3D objects have more mass and surface area to overcome air resistance.

4. Are there any drawbacks to thinning an object for increased speed?

Thinning an object for increased speed can make it more susceptible to external forces, such as wind or impact. Additionally, thinning can also decrease the structural integrity of the object, making it more prone to breaking or deforming.

5. Can thinning be used to achieve super-fast speeds?

While thinning can contribute to increased speed, it is not a magical solution for achieving super-fast speeds. Other factors, such as propulsion, energy sources, and aerodynamics, also play a significant role in achieving high speeds.
