Interstellar Time Travel Explained | How Wormholes Work? | Dhruv Rathee

Traveling to other habitable planets in different galaxies is currently impossible due to vast distances, with even the closest galaxy, Andromeda, being 2.5 million light years away. Theoretical concepts like wormholes and white holes offer potential shortcuts for intergalactic travel, even though their existence remains theoretical and unproven.
Insights
- Interstellar travel to other habitable planets in distant galaxies is currently unachievable due to the immense distances involved, with even the closest galaxy, Andromeda, being 2.5 million light years away from Earth.
- Theoretical concepts like wormholes, proposed by Albert Einstein and Nathan Rosen in 1935, offer a potential solution for faster-than-light intergalactic travel, connecting two points in space-time and potentially utilizing white holes as exit points, despite the theoretical challenges presented by the Second Law of Thermodynamics.

Interstellar Travel: Wormholes and White Holes
- Traveling to other habitable planets in different galaxies is currently impossible due to the vast distances involved.
- The Milky Way Galaxy, where Earth is located, is closest to the Andromeda Galaxy, approximately 2.5 million light years away.
- Traveling to the Andromeda Galaxy at the usual speed of 28,000 km per hour would take 94.5 billion years.
- Even if technology allowed travel at the speed of light, it would still take 2.5 million years to reach the Andromeda Galaxy.
- Wormholes are theoretical shortcuts in space-time that could potentially allow for faster travel across vast distances.
- Wormholes, scientifically known as Einstein-Rosen Bridges, were theorized by Albert Einstein and Nathan Rosen in 1935.
- Wormholes connect two points in space-time, potentially providing a shortcut for intergalactic travel.
- Wormholes operate in higher dimensions, allowing for shorter paths through curved space-time.
- White holes, the theoretical opposite of black holes, could potentially be exit points for wormholes, allowing for travel between galaxies.
- The concept of white holes, like black holes and wormholes, is based on Einstein's Field Equations, but their existence and formation remain theoretical and unproven.

"White Holes: Theoretical Impossibility or Reality?"
- Some scientists argue that white holes cannot exist due to violating the Second Law of Thermodynamics, which states that entropy cannot decrease in a system, likening it to tearing a paper to increase entropy irreversibly.
- Despite the theoretical impossibility, in 2006, scientists observed an astronomical event named GRB 060614, hypothesized to be a white hole explosion, as no evidence of a star was found, marking the only known observation of a white hole to date.
- Scientists have created a magnetic wormhole in a laboratory using high-temperature superconducting material, Yttrium Barium Copper Oxide, and liquid nitrogen, demonstrating the separation and bending of magnetic fields, offering a potential alternative to traditional wormholes for faster-than-light travel.
