You take a round trip to the star Sirius, a distance of 8.6 light years away, on board a spacecraft traveling at 99% the speed of light. When you return to Earth, 17.2 years have elapsed on Earth. But due to Einstein's theory of relativity, you will have aged by 172 years 24 years 2.4 years 17.2 yearsThe fastest space probe currently flying (perhaps one of the Voyagers) might be able to reach a nearby star system in about 50,000 years 5,000 years 50 years 500 yearsElon Musk of Space-X plans to send a human crew to the nearby Proxima Centauri star system by 2050.

As per policy, I am bound to answer only one question. NASA launched Voyagers in 1977 to trek across the solar system. On each was a 12-inch (30 centimeters) large gold-plated copper disk. Both spacecraft visited Jupiter and Saturn, then the twins parted ways: Voyager 1 studied Saturn's moon Titan while Voyager 2 swung past Uranus and Neptune. In 2012, Voyager 1 passed through the heliopause that marks the edge of the sun's solar wind and entered interstellar space; in 2018, Voyager 2 did so as well. Now, the two spacecraft are chugging through the vast outer reaches of the solar system. Not until about 20,000 years from now will the Voyagers pass through the Oort cloud — the shell of comets and icy rubble that orbits the sun at a distance of up to 100,000 astronomical units, or 100,000 times the average Earth-sun distance — finally waving goodbye to its solar system of origin. so, the option (a) is right.SpaceX is only planning for Mars colonization. Alpha centuari is just a proposal. so, it is False

Two twins leave Earth at the same time in two different space ships. Jeremy travels twice as fast as Marnie. What will happen to them after they travel for one year of time back on Earth?
According to the formula E=mc2, mass has to travel at the speed of light before it can produce any energy energy can travel much faster than light (in fact its speed can be the speed of light squared) a little bit of mass can be converted into a substantial amount of energy when two masses collide, we always get a lot of light Einstein was a male chauvinist twice over
A ship is heading off to Bernard's star at 0.700c. As it passes a space station (at rest with respect to the Earth) a few days out from Earth, the ship fires a "photon torpedo" in the forward direction and another in the reverse direction. the torpedoes have a speed relative to the ship of 0.700c. On a space-time diagram, determine the direction and speed of each torpedo as seen by the station. Check your answers using the relativistic addition of velocities formula.
