Would it matter if Earth was expanding as opposed to Pangea and moving continents? Is there even a difference one way or the other as to what 'it' means?
One major piece of evidence for expanding planets and moons is the detection of geological activity on these celestial bodies. This includes volcanic eruptions, tectonic activity, and other signs of internal heating and movement. Additionally, the analysis of their surface features and composition can provide clues about their past growth and expansion.
There are several proposed mechanisms for planetary and lunar expansion, but the most widely accepted theory is through internal heating. This heat causes the materials within these bodies to expand and can lead to the formation of new crust and surface features. Another proposed mechanism is the accretion of material from external sources, such as comets or asteroids.
There is currently no evidence to suggest that Earth is actively expanding. However, there is evidence of past expansion through the presence of ancient shorelines and other geological features that indicate changes in the Earth's surface over time. This is known as "continental drift" or plate tectonics.
It is possible that expanding planets and moons could lead to catastrophic events, such as volcanic eruptions or earthquakes. However, the rate of expansion is typically very slow and these events would likely occur over a long period of time. Additionally, the internal heat and expansion of these celestial bodies is a natural process that has been occurring for billions of years without causing major catastrophes.
The impact of planetary and lunar expansion on life is not well understood. Some scientists theorize that expansion may have played a role in the evolution and development of life on Earth, as it could create new habitats and environments. However, if the expansion were to occur too rapidly, it could potentially lead to mass extinction events and disrupt ecosystems. Further research is needed to fully understand the potential impact on life.
