Why don't Star Trek vessels experience time dilation while travelling at impulse speeds

This may be a little complicated but I will try to keep it simple Einstein's laws of Special relativity says that the closer you get to light speed the more of a time dilation effect you get. So if ...

Do ships in Star Trek that can land on planets use impulse drive to reach space?

I have read many sources and understand that impulse drive can be very fast. A quarter of impulse can be way faster than the escape velocity on Earth (11 km/s) or on the Sun (600 km/s). Does this ...

How fast can impulse drive propel a ship?

Impulse drive, how fast is it? Throughout star trek we see various ships travelling at fractions of 'Impulse drive'. An impulse is a unit of force and thus converting to speed is difficult. Here are ...
