"'Close to the speed of light' means, like, 99% of the speed of light" So, you are saying that it is possible to accelerate human body to 99% of speed of light

"'Close to the speed of light' means, like, 99% of the speed of light"
So, you are saying that it is possible to accelerate human body to 99% of speed of light without transforming the body into a massless particle?
- tsimionescu 2y agoYes. It will never be possible to get to 100%, but I principle anything below that is possible. Not just 99%, but 99.99999999% or however many you want. Of course, it's not actually feasible, you would need galaxies worth of energy to do so. But for something like 10% or even 50% of the speed of light, it's not even that implausible.

- ithkuil 2y agoOur current speed is 99.999999% the speed of light, according to some frame of reference, 10% according to another frame of reference and 0% according to another. A lot of work is done by the words "get to" which is colloquial for "accelerate".
- DHRicoF 2y ago> Not just 99%, but 99.99999999% or however many you want. Badly enough, even that's not true. We have a frame of reference given by the cosmic microwave background. When you move faster and faster at some limiting speed will create pions that will slow down the particle creating an effective slower max speed. https://bigthink.com/starts-with-a-bang/speed-limit-below-speed-of-light/ https://bigthink.com/starts-with-a-bang/speed-limit-below-sp...
- icehawk 2y agoYes. Gven the average mass of a human body at 66kg: (((1/sqrt(1-((0.99c)^2/c^2)))--1) 66kg * c^2) = 50,000PJ which is the amount of electrical energy the entire US produces in 0.287h???
