Its actually easier to launch stuff out of the solar system than to slow stuff down enough to fall into the sun

shhhhhh they don't understand Hohmann Transfers, we can send them there regardless.

Yeah, and antimatter converts to pure energy with e=mc^2 what means that 60 grams contains like Hiroshima worth of energy

Smarter people than me on the internet calculate that at constant 1g you only need 2.5 years to get very close to speed of light. So I guess you accelerate fast enough and reach 'almost speed of light' very early in your travel and total time is almost as if you traveled at speed of light the whole time.

The closer you get to lightspeed, the slower you accelerate (from an outside perspective). It's actually close to lightspeed for most of the time.

I just used the calc, it's closer to 152 years. Which I assume means acceleration at 1g for about a year to reach .999c, and deceleration for the same time.

I just confirmed with dV= a*t, a year of 1g(9.8m/s/s) gets you just over the speed of light. I think it's more complicated than that, If I remember right relativistic speeds require more and more energy to accelerate so you can't ever "reach" light speed.

Most of the journey is spent traveling very close to light speed. It's not a linear ramping up and ramping down of speed, since it takes more energy to accelerate the closer you get to light speed. Rather you quickly accelerate to near light speed and spend most of the trip working on that last small bit of velocity.

9.974 years

It's only 9 years for you!

Beautiful, Bernie is much preferred, thank you!

I'm pretty sure that's a sidequest in Starfield. The ECS Constant colony ship set off in 2140 to colonise a planet, arriving in 2330 at the planet Paradiso, which had become a luxury resort planet for the rich, because shortly after the ship left, humanity invented the grav drive and every ship just zoomed right past them.

If we can go back in time, we can recount the election, find those missing votes and have the person Americans actually wanted become president. Al Gore

Harambe was a consequence, not the cause.

I’ll just ask Grok to build me something…

That would be like so could man.

And not only would something have to be alive there, they would have to have be intelligent and have formed civilization that is currently using radio technology, AND be at a point where they are actively listening at the point in which the signal arrives there, assuming we can send a signal strong enough to be received at all at that distance, which may be doubtful unless we put in a lot of effort as a species to send a super-signal to a distant star.

For reference, Earth has had life for somewhere between 3.5 to 4 billion years. Our entire species has lived for around a million years at most, and out of that time we only figured out electromagnetism in the last couple centuries, and only started actively using radio in the last century.

A hundred years out of ~4,000,000,000 is microscopically small. If another species developed their technology a century or two before or after us we have no way to know if they would possibly notice or recieve a radio signal, but it's far more likely if the planet had intelligent life that it would have developed some number of millions of years before or after us. We don't even know if other intelligent beings would use radio.

I'm sure there are or have been plenty of sapient beings emerging in the galaxy but they could have had entire, multi-million year epic stories play out and rise to glorious intergalactic heights with grand stellar-empires, and then either collapse in a million-year war or evolve past material consciousness, and still have been just a pinpoint in the timeline somewhere between the extinction of our dinosaurs and like, the evolution of early whales.

To say we are ships passing in the night would be a vast understatement of the problem.
