🚀 1. SpaceX Starship for Earth-to-Earth Travel

In 2017, Musk proposed using SpaceX’s Starship rocket for ultra‑rapid Earth transport. By launching into suborbital space, Starship could travel “parallel” to Earth’s surface—potentially flying New York → Shanghai in ~39 minutes, or even Delhi → San Francisco in about 30 minutes . While no secret “gravity travel” system has been activated, he did tweet:

“This is now possible.”

This concept is still theoretical. There’s no indication of any confidential, gravity-based infrastructure being built or tested.

2. Hyperloop: High-Speed Vacuum Tunnels

Musk first outlined the Hyperloop concept in 2013: passenger pods traveling through low-pressure tubes at near-supersonic speeds (~760 mph / 1,220 km/h) . Though several companies are testing prototypes, the project is far from operational—and again, not based on gravity travel.

3. Vacuum Tube Tunnel Proposal

In 2024, Musk floated an idea of a $20 trillion vacuum-tube tunnel connecting cities like London and New York in just 54 minutes, with speeds up to 3,000 mph . While still speculative, there’s no sign of secret testing or “activated projects” underway.

🧭 Final Takeaway

While Elon Musk continues to envision futuristic transport—hyperloop systems, vacuum-tube tunnels, and even rocket travel across continents—none of these have been secretly activated or recently tested as “gravity-based” systems. The recent headlines you might’ve seen seem to blend these ideas with speculative hype rather than factual developments.
