These include the time that it takes for the driver to recognize a potential hazard and decide that braking is the best course of action and for the car to complete the braking process. If it turns out to be an actual drive it would be amazing and life changing event but I'll believe it when i see complete evidence that supports it.Several factors are involved in determining how long it takes a moving vehicle to come to a complete stop. The EMDrive I'm skeptical of course, anyone following scientific progress for a few decades learned that the higher the stakes the more skeptical and more proof is required. We could reach Mars in less than a couple of months, would become less dependent on gravity assist etc. To give and idea voyager that is now reaching heliopause, the limits (arguably) of our solar system after 40 years, travels at 17Km/s, these ships could reach our fastest probe that was launched more than 40 years ago in 10 years if they left now. These drives require a marginal percentage of fuel when compared to current rockets and are very efficient, the disadvantages are the high electric power needed and low thrust (they need a lot of time to reach fast speeds).īut for solar system travel they seem to be very promising, and NASA stated that they could reach 90Km/s. Not emdrive, electric drives Like VASIMR (although after 5 years of marginal progress I'm starting to loose confidence in this project) there are plenty of electric drives popping up, using ion thrusting etc. The bad news is that even at 10% the time lapse isn't very big so the difference in years wouldn't be that many. The good news is that for the people on the ship time would pass slower so it would take less time for them. If, by using other propulsion method you could reach 10% the speed of light, which would be ideal (although i don't see it in a near future at all), you could reach it in 100 years. You also need a lot less fuel than chemical rockets. I chose electric engines because they already exist and although they have low thrust and are at the beginning of implementation, they aren't ready for human or interstellar trips yet but are the closest thing we have, if you can use higher power outputs like nuclear and have enough fuel you could reach quite decent speeds. The fastest object ever we've created travels at 17.145 km/s (0.005% the speed of light), so it would take something like 175 000 years to reach it.įuture technology but close to present (electric engines for example) could according to NASA reach 90 kms (0.03% speed of light) meaning 33 333 years to reach it. Short of inventing some kind of Star Trek-esque warp drive or wormhole technology, we're not getting there anytime soon. At this speed it would only take around 43000 years.Įven travelling near the speed of light it would take at least 10 years to get there! If it was even easy to get near the speed of light the amount of fuel needed would be enormous! The fuel would also add to the mass that you need to accelerate making it more difficult. The fastest mad-made object ever built, the Helios 2 spacecraft, reached a maximum speed of 157078 mi/h (252792 km/h). So 10 light years is around 58.79 trillion miles (94.61 trillion km).Īpollo 10 set the record for the highest speed attained by a manned vehicle at 24791 mi/h (39897 km/h). This is approximately 5.879 trillion miles (9.461 trillion km). A light year is the distance light can travel in one year in a vacuum.
