How far we have explored space and how far can we go?
141 AU which is equal to 141 times of the distance between Earth and Sun, Voyager 1 is able to travel the most in history. Even after travelling at the speed of 17 km/sec in space, which may sound a lot, it will take 1,700,000,000 years for Voyager 1 to cross the Milky Way Galaxy. Proxima Centauri, the second closest star from Earth after Sun is 4.2465 light year away and it would took 40,000 years for Voyager 1 to reach it. Parker Solar Probe recorded the highest speed in space which is 692,000 km/h and still it would take more than 50,000 years to reach destinations like Proxima Centauri. Now if we need to explore exoplanets, the factor we need to devolop is speed. Out of many ways, most well known way to travel faster in space is Warp Drive where we use Antimatter to gain speed. Antiatoms are successfully built and research over Antimatter are being done. Big Bang should have produced huge amount of Antimatter which may be lying far away in Universe.
