О скорости. Теоретически, при очень малом ускорении в 1g можно приблизиться к скорости света за 8 лет. Observed from the spaceship, accelerating at 1g would reach 0.77c after 1 year.
Observed from Earth, it would take 1.19 years, and would have travelled 0.56 light years.
After two years on the ship at 1g, you would reach 0.97c, however 3.75 years would have elapsed on Earth and you would have covered 2.90 light years. Viewed from the Earth, your mass would have increased 4x, and you would be a quarter of your size!
After five years on the ship, you would reach 0.99993c. 83.7 years would have elapsed on Earth, and you would have covered 82.7 lightyears. You would stand about an inch high, and have a mass of about 6 tons as seen from Earth, though you would not notice any difference.
After 8 years, you would reach 0.9999998c. 1,840 years would have elapsed on Earth. Great, you are far from what was your home. 400 US presidents came and went. What is more, you are now 1mm high and have a mass of 140 tons.
