First colour image from JWST Today at 10pm

I thought it was a black hole causing the lensing

Taken from nasa website
Why do some of the galaxies in this image appear bent? The combined mass of this galaxy cluster acts as a “gravitational lens,” bending light rays from more distant galaxies behind it, magnifying them.

It may well be. But you realise just how futile it is to even think about given the distance between just one tiny light spot to another which on a screen looks quite close, but is actually tens of thousands of light years of space between them, so the chances of a trip from one to the other even if both galaxies had space faring life that could travel at light speed would be insignificant as they'd all be long gone by the time a ship reached either side

Oh god yeah I appreciate the crazy incomprehensible distances involved and that it's unlikely we'll ever know.

So it is partly black holes if it's based on mass of galaxy

The thing that really put this into context for me is that image of how far we’ve sent radio signals into space. I’d always assumed we’ve been beaming these out a lot further and the fact we’ve had no response is a sign we might be unique, at least in our little corner of the galaxy. Now… I want to believe!

Oh forgot to mention add time dilation into the mix too, assume one makes it across and survives through cryo stasis etc, upon their return back home they will find that nothing they knew remains due to the effect of time dilation from travelling at such speeds.

Space travel is effectively a one way journey, for those you leave behind.

Barring some sort of transhuman future.

Unless warp drives turn out to actually be a thing, where it's a bubble of spacetime moving superluminally not the passengers in the bubble, so they don't experience time dilation.

Warp Drive Is No Longer Science Fiction. The Physics of Faster-Than-Light Travel

This gives us a strong mathematical basis to study warp drives.

It's still immense distances though, just in our own galaxy, let alone inter galactic travel

Wormholes / 4D travel wouldn't be susceptible to time dilation. Prefer those concepts over standard spacetime travel which from the perspective of Earth bound humans is like firing Voyager into the galaxy. Once it's out of range, it may as well not exist.

I want to know what they would look like if I was looking at it though. Still very cool. awe inspiring.

Given that Webb operates in the infra-red spectrum, which is outside of the very narrow visible frequency range that our eyes are able to detect, you would see absolutely nothing. This is precisely why Webb was built - to see the light that normal cameras and telescopes can't.

I thought it was a black hole causing the lensing

Black holes DO cause lensing, as does every mass in the universe, but on these scales it's the mass of entire galaxy clusters which cause both the lensing and multiple images of the galaxies further beyond to appear.
