Eli5. A question trying to understand if you would see events on a planet happening faster if you moved towards it

395 viewsOtherPhysics

If a planet was 5 million light years away from earth, the James Webb from earth would see it as it was 5 million years ago.

And say if we continued to watch this planet from the earth we would see events happening at the same speed on earth.

if I was to fly towards this planet in a space ship with a telescope, would I see events on the planet being sped up and if I was to fly away would events happen in slow motion?

Ha! And I’ve been wondering about basically the reverse all week.

Just reading some scifi where a giant object disappears from a solar system. But for whatever reasons our protagonists dont get to see it happen. Even tho their ship was basically right beside it.

So they jump their FTL ship a few light-hours away and then they can watch the disappearance happen.

And I’ve been wondering if that would work all week lol.
