There is more than one way to get the Lorentz factor. For very large velocities, where Lorentz contraction is more significant, the last choice "percent of speed of light", would be the easiest. more

To help you determine what time to choose, you can choose a destination. Once you do this, the speed and distance you traveled will be calculated to find out how much time has passed.

The faster you move relative to someone else, the slower time goes for you than it does them. The effects of this are extremely small until you start to move at extremely high speeds.

An example of this is the twin paradox. If there were two twins that were 10 years of age and one of them was on a space ship traveling 90% of the speed of light for 10 years, they wouldn't be the same age anymore. The one on Earth would be 20 years old while the one on the space ship would be less than 14 years old. This is called time dilation or lorentz contraction.

Another example of this is traveling from one side of our galaxy to the other at 99.99999999999% of the speed of light. Our galaxy is 100,000 light years across, which means that if we're traveling at almost the speed of light, it will take us about 100,000 years to cross from one side to the other. However, because of time dilation, even though 100,000 years would have passed on Earth, only about 2 weeks would have went by inside of your space ship.

Here you can find a list of some speeds that you can use to adjust the velocity with, and change the Lorentz factor.

This is your travel guide. Choose your destination, select the correct unit in the
time adjuster, and put in the value. So, for example, if you want to travel to Saturn,
then make sure "AU" is selected instead of "Miles" and then type in the value "8.5".

The Milky Way Galaxy is about 100,000 light years across. The closest start is 4.2 light years away. The closest galaxy is 2,520,000 light years away. Deep space is very very very far away.
