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.

Constant acceleration at 9.8m/s^2 in a given direction will bring you close to the speed of light eventually, but yeah, I'm also not super sure how this math checks out

9.974 years

It's only 9 years for you!

Just imagine sitting on a spaceship for 151 years to find out they got there first because in 151 years space travel tech has improved so much they can travel there in 35 years.

It's not just blanket entire body experience that force including internal organs.. So i guess sleeping with tgat would be more than just uncomfortable

I say have a spinny ship that does that with the shape of the ring. Some kind of parabolic bullshit I'm sure there's a way to get it to math without having to have a 1g ring and a 3g ring but that works too

It would only save you a few months

Great Scott!

Oh and also thats just the pure energy for acceleration/deceleration, not life support, steering, thrust ineffeciencies, take off, landing etc... 😅

So 340 PWh per person. A couple of guys with a static bike and a dynamo and that's it😜

Note: the Earth receives 170 PWh of energy from the Sun in a year.

No, the people in the ship will experience less time then 152 years. Relativity tells us the faster an observer is moving, the slower it moves through time.
