Our current space technology is extremely limited. Spacecraft don’t "fly"—they’re like throwing a dart at a target. You launch them with force, and if aimed correctly, they hit their destination. There’s no real control after launch.

To truly maneuver, a ship would need thrusters on every side and an impossible amount of fuel. That’s why our Mars probes don’t "fly" there—they’re just flung toward Mars and crash-land.
Fuel and Physics Make Interstellar Travel Impossible
Even going to the nearest star in a reasonable time would require more energy than exists in the entire universe. And that’s just the fuel problem.
The Human Body Can’t Survive Long in Space
Without gravity, muscles and bones waste away. We can only stay in space for short periods before our bodies break down.
If Aliens Can Visit Us, Our Science Is Wrong
If aliens are traveling here, they’ve solved problems we can’t even imagine:
