- Purpose of use
- Determining how fast the creation of the universe would need to be for billions of years to be equivalent to 4 days from the observer
- Comment/Request

- Purpose of use
- Time to distant stars at 1G acc. to mid-point &1G dec. to destination.

- Purpose of use
- Would love to see 'real world' speeds with highly fractionalised results. Eg the tiny relativistic effects of travelling at 100kmh for 2 hours

- Purpose of use
- Just making sure my own calculations of time dilation are correct. Doing this just for fun.

- This is an attempt to reconcile the theory of time dilation with the time it takes light to travel 1AU. Assuming that time is equal to distance at C, the observed time it takes light to travel 1AU is approximately 8 minutes or 480 seconds. However, using the time dilation equation, if I were traveling at 99.999847227644% C the distance of 1AU, I would observe the passage of approximately 274,602 seconds or 3.24 days on on Earth. How does physics reconcile this discrepancy?

- Purpose of use
- Wondered how fast a space ship would have to be going to make the trip to Proxima Centauri take only 15 minutes for the people on the ship.

- Purpose of use
- calculating when starships would arrive in relative time to each other for building an TTRPG setting.

- Purpose of use
- Calculating time dilation for spacecraft traveling to tau ceti star from earth. Reading Andy Weir's book Project Hail Mary.
