my guess is that the first space ships that first make the jump will go traveling closer to the speed of light. That technology won’t be available for at least 50 years and maybe 100 years. most of the space travel we’ll see for the next century will be in the solar system.

I think we need to invent cold fusion and cancer cure first before I can believe our spaceships attaining speed of light.

Even at light speed it's not fast enough for real distant exploration. But it's a good start. The Andromeda Galaxy is only a couple million light years away, so at the speed of light it would take about 2.5 million Earth years to reach it. Just one way.☺

most of space travel in the next 50 to 100 years will probably be low earth orbit, not much farther than the so-called International Space Station.
