The Earth is not expected to explode. However, its ultimate destruction is predicted to occur far in the future, primarily due to the evolution of the Sun. In about 7.59 billion years, the Sun will enter its red giant phase, expanding significantly. During this phase, the Sun will likely engulf the Earth, vaporizing it as it expands. This process will effectively destroy the Earth, but it is an extremely distant event. Before this, other catastrophic events such as asteroid impacts or supernova explosions near Earth could cause mass extinctions or severe environmental damage, but these would not cause the Earth itself to explode or be destroyed. In summary:
- Earth is likely to be destroyed by being engulfed by the expanding Sun in about 7.59 billion years.
- Earlier events like asteroid impacts may cause large-scale damage or extinctions but will not destroy Earth.
- The Earth will not "explode" but be consumed or vaporized due to the Sun's expansion.
This fate is a very long way off, so there is no imminent risk of the Earth exploding or being destroyed soon.
