Mars isn't "impossible" it's entirely possible! Just really really expensive. It needs some things in place before it's remotely practical. Space elevator? Legrange spaceports? Moon bases for sure.
Meanwhile the time it takes to travel 1 light-year is critically important to whether aliens will visit us or not.
1 per hour? We'd be crawling with aliens long ago.
1 per day? They'd be here by the ton.
1 per week? Still tons of them.
1 per month? Getting serious. They for sure would be here already, just not a lot of them.
1 per year? Yeah, some would be here but not many. This could be our current situation. The few that arrive have spent a PILE of money & time on it. Whatever they're after must be really valuable to them.
Over 1 per 2 years means they would likely be few & far between.
👍🏼 Based on 30 to 60 light years distance.
Yeah, are sentient beings made of light? They're probably made of, you know, matter! And how long it takes a spaceship of any sort to travel 1 light-year is a critical element here.
Star Trek speeds? (I think they go like 8 light-years an hour?) We'd be crawling with aliens. 10 years to go 1 light year? Not so much.
Well there's Sci-Fi ideas about FTL travel. Wormholes (natural or otherwise) to teleportation links (not natural!) to bending or warping space itself.
Those aren't estimates, they're "if this? then that" eh? The focus is on how many alien contacts we'd have by now.
If you wanted to travel 200 miles on Earth? How often would you go if you traveled 1 mile a second, a minute, an hour or a day? 1 mile a month = that's a once in a lifetime journey, round trip.

Wut?
It takes light one year to travel one light-year, this is by definition what a light-year is.

The speed of light is the hard cap; we will never go faster.
All your estimates are way optimistic. It's more like 3-5 years for every lightyear, once everything is "perfected".

Then will simply increase the speed of light
