How is it that the?

fastest humans have ever got a space craft to go is somthing like 150,000 miles an hour. Cause in space there is in gravity slowing you down. And if this is true is there a way to go faster like using explosives or somthing.

I really tried not to sound like an idiot so take it easy please.

Our speed is limited by our technology.
Most are by chemicial propulsion and nuclear.
There is a limit to how fast these systems can go.

We can increase the speed by sling-shoting around a planet like Jupiter using its gravity to go faster.

The record for the fastest spacecraft of all is held by the twin Helios probes that were placed in orbit around the Sun. Both these vehicles reached top speeds of around 150,000 mph (250,000 km/h) at closest approach to the Sun in their highly elliptical orbits, Helios 2 being marginally the swifter. The massive gravity of the Sun made it possible.

For now, that is the best we can do.

There is gravity in space, only it decreases the further you are from any objects with mass (planets, asteroids, etc.) Gravity is what actually brings satellites / probes to the highest speeds. It's a technique called the gravitational slingshot. We use the gravity of a planet to draw the probe in, and then slingshot it out of that planet's orbit.
