what would it take to build and accelerate an object to 295000 kms/s? Like seriously, would it take nuclear propulsion or is it antimatter engine or solar sail?

- lsllc 2y agoThe speed of light is 299792.458km/s so according to a quick Google search it takes 4.28x10^17J to accelerate 1kg to 0.98c.
- fecal_henge 2y agoThats nearly an entire camenbert.
- vivzkestrel 2y agook so obviously we cannot slingshot someone with that speed or even use chemical rockets to reach those levels. So are there newer propulsion systems being worked upon?
- lsllc 2y agoIon thrusters [0], solar sails [1], nuclear pulse propulsion [2] are all things that have real research being done on them. There's more esoteric stuff (theoretical) such as the Alcubierre Drive [3] (Warp drive!) that's more of the realm of sci-fi. If you can maintain a constant 1g of acceleration, you'd get to ~0.99c in approximately 1 year -- but you need to carry/provide the energy to fuel whatever propulsion system you're using and the amount of fuel needed to maintain that 1g of acceleration increases as you get closer to c.
