How Fast Can We Travel In Space

That s the mass of a paper clip.
How fast can we travel in space. On this scale the distance to alpha centauri a would be 276 kilometers 171 miles. To get to lower orbit astronauts have to get to 17 500 miles per hour and to do that they have to change. Light is the physical speed limit of the universe as far as we know scientists take great pains not to declare anything conclusively because things have a habit of being disproven and the. The fastest outward bound spacecraft yet sent voyager 1 has covered 1 600 of a light year in 30 years and is currently moving at 1 18 000 the speed of light.
At this rate a journey to proxima centauri would take 80 000 years. The fastest object ever launched into space is the voyager 1 probe and it would. I think a hundred years ago we probably wouldn t have imagined a human could travel in space at almost 40 000 kilometres per hour says jim bray of the aerospace firm lockheed martin. Alcubierre s design called for an american football shaped spacecraft with a flat ring attached to the ship.
Space time would warp around it accelerating the ship to as fast as 10 times the. When you go to space you have to get enough speed to get out of earth s gravity field. If we were to shoot this laser at the spacecraft for about 10 minutes in order to reach one tenth the speed of light the spacecraft can weigh no more than a gram. Once at a steady cruising speed of about 16 150mph 26 000kph in orbit astronauts no more feel their speed than do passengers on a commercial airplane.
Relativistic space travel in the previous example where we traveled to andromeda galaxy the maximum velocity was almost 3000 times greater than the speed of light c 299 792 458 m s or about c 3 10 m s using scientific notation.
