10 खरब वर्षों में पृथ्वी का क्या होगा? | What will happen to Earth in 1 trillion years? | Hindi Fusion TV |
Predicting what will happen to Earth in 1 trillion years involves a lot of speculation based on current scientific understanding of astrophysics, stellar evolution, and cosmology. Here’s a concise overview:
In 1 trillion years, Earth will likely no longer exist in its current form. The Sun will have evolved significantly by then. In about 5 billion years, the Sun will expand into a red giant, potentially engulfing Earth or at least rendering it uninhabitable by vaporizing its surface. After that, the Sun will shed its outer layers, becoming a white dwarf, leaving behind a cold, dark remnant.
If Earth somehow survives the Sun's red giant phase (e.g., if its orbit shifts outward due to the Sun losing mass), it would still face a bleak future. By 1 trillion years, the universe will be in a phase called the "Degenerate Era." Most stars, including the Sun, will have burned out, leaving behind white dwarfs, neutron stars, and black holes. Star formation will have largely ceased due to a lack of available hydrogen gas.
