Does the object exist?

The two examples below give the same result.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Example() { if (rigidbody) Debug.Log("Rigidbody attached to this transform"); } }

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Example() { if (rigidbody != null) Debug.Log("Rigidbody attached to this transform"); } }
