Correct me if I'm wrong, but one time I heard someone say that a rocket, such as a missile, model rocket, or even a NASA Rocket, has infinite acceleration until its fuel burns out. If this statement is true, then in a hypothetical situation, where we have a rocket being launched straight into the air, and the rocket will never run out of fuel, will it just keep accelerating forever and ever? Could it reach the speed of light, or even faster? Tell me your thoughts.
if you are in space and in a complete vacuum (so absolute no drag or friction), even the smallest force can accelerate an object until it reaches the speed of light. that is, if the force can be sustained long enough.
Yeah. Nothing can get to light speed because it will take all the energy in the universe to do so. @randomusername
If you when the speed of light, graveling would feel instant, but everything around you would age. @randomusername
I'm too lazy to read read the comments below so somebody might have already answered this, but basically as you get closer to the speed of light the apparent mass of the object you are accelerating gets bigger and bigger, meaning it takes more and more force to push it. The mass gets larger and larger as you get closer and closer to the speed of light until it doesn't matter if you have the rocket force of 10 Saturn Vs, you aren't going to accelerate the object even an extra inch per second.
@randomusername Relativity is real. It has been studied and measured. Perhaps we humans don't understand it entirely, I do not know. What I do know is that if satellites did not account for time dilation, many things we use would not work. Right now, we live in an age where people look at science, decide they don't like what they see and make up their own story. Don't fall into that trap, challenge yourself to learn.
The thing is, if you tried to walk 1kph faster than the speed of light, it will take you infinitely long to take that step. @randomusername
It’s physically impossible to go past the speed of light due to how time works. @randomusername
Yes. Think about it. It’s generating thrust. That thrust won’t randomly cease to accelerate the craft, will it?
@randomusername @F104Deathtrap thanks for commenting, I've always wondered about this and I'm glad you gave me your theories on this.
Relativity prevents objects with mass from approaching the speed of light. Through a phenomenon called time dilation, time begins to move slower a d slower for fast-moving objects.
Read about it here.
This all might sound like sci-fi hocus pocus, but it is actually part of the GPS technology we take for granted every day. Distant satellites have to compensate for time dilation in order for GPS to work.
