We evolved in a surroundings of distances, speeds, and time increments that have shaped our "common sense" to expect that object speeds are additive. If a car is traveling at 30 miles per hour and you fire a bullet straight ahead at 1700 miles per hour we expect that a stationary observer will measure the speed of the bullet as 1730 miles per hour. And that (to a very high degree of practical accuracy) is what happens.
But the special theory of relativity showed us that our "common sense" doesn't work very well at much higher speeds approaching the speed of light. The simple answer is that any observer will measure light as moving at the speed of light regardless of the relative motion of the source emitting the light. (And only particles with no mass can and must travel at the speed of light.)
FWIW, my understanding is that what increases as an object accelerates is its inertia which is due to its resting mass and to the kinetic energy it has. Because the inertia of an object is increasing with its speed, each time you add energy to it you get a little smaller speed change than before. It is "as if" its resting mass is increasing.

Are you in Space?
Sir! I'm going to need you to step away from the blunt.It's like we live inside a Bubble and the outer walls are the extremes where things become distorted. Except that wall isn't at the extreme edge of the Universe, it exists in everything at the extreme of any trait of Existence. Both inside the Bubble and the Bubble.
Unless, the Bubble is just our Minds inability to conceptualize beyond a certain point. We need the next Newton or Einstein to figure out the easy to remember equation.

This is the important bit. Speed of light is relative to the observer, so anyone in the car will just see the lights turn on and photons fire out the front of the vehicle, identical to a stationary one. Anyone outside the car wouldn't see photons project from the front of the car (if such observations were possible to be made).But the special theory of relativity showed us that our "common sense" doesn't work very well at much higher speeds approaching the speed of light. The simple answer is that any observer will measure light as moving at the speed of light regardless of the relative motion of the source emitting the light. (And only particles with no mass can and must travel at the speed of light.)
As you approach the speed of light with your headlights on, however, you would still measure the light beam racing away from your car at 186,000 miles per second (c). A 'stationary' observer watching this happen, though, would not then measure the beam's speed at almost twice c. Relativity says that all observers always get the same measurement for c .

Given enough time, you can accelerate at 1g just fine.Once you hit C, you see some serious shit. Actually, I don't think you see anything because you'll probably be dead from the G forces of having to accelerate at that speed.
It sounds like you're talking about Leo Susskind's holographic universe. That was a big idea like 20 years ago, but when GR (as we know it) goes the way of the Dodo, I'm not sure either it still is or will be.Please do the Math, bro.
