Disclaimer: Assume the universe as part of a larger scheme, not the literal definition.

From what I understand, it is impossible to determine the speed your absolute speed, as all motion is relative. So does this mean that, theoretically, the universe could be moving at incredible, near-light speeds?

After all, the Earth moves at some 65,000 mph, the solar system moves at 559, 234 mph, and the Milky Way is moving at 1.34 million mph.

Everything in the universe does already move at the speed of light, to any observer at right angles to your time vector.
*
Remember, we live in a 4-dimensional universe according to Einstein (at least 4, there may be more dimensions.) We are traveling at the speed of light already, in the time dimension.
*
This is exactly how and why time changes at near-lightspeeds. Think of being on the freeway, and looking out the window at the car next to you. It appears to be still, even though you are both traveling at 60mph. Think of this as traveling through the time dimension. When you take the off-ramp, and look behind you, that car is now speeding past you. Time is now passing at different rates for each of the cars.
*
This is not a new idea, it is a different way of explaining relativity. In this view, there are no speed changes, just direction changes. You have changed your motion vector from the time direction to one of the spatial directions (which becomes your new time vector if you go fast enough.)

Once again with respect to what ??? There is no intersection or road in space where we measure a velocity. Measuring a speed without a reference makes absolutely no sense. You can't say the universe is moving incredibly fast without giving a reference. That would mean a point outside the universe which is impossible.\\

P.S. If the entire universe is, we would never know it. Sit in a plane going 500 mph and look around. You're at rest with everything in your universe (the airplane). You measure your speed as zero.

Yeh. It may even be possible that the universe is moving AT the speed of light. Infact, wrt light. the universe moves AT the speed of light. Though you can never experiment and find out, since motion is relative and neither space nor time is absolute !

Yes this is almost a certainty because time is elative but the spped of light in a vaccum is constant, there fore the fastest you could ever be travelling is 99.9% the speed of light because light will always move faster.

An example, assume you are in a space ship that is moving 99.9% the speed of light, when you turn the head lights on it will always light infront of you therefore moving faster than you and moving at the speed of light

If everything is moving in the same direction you won't know how fast you are going, as everything is relative. If only parts of the universe were moving at this speed you would see huge red and blue shifts, which we don't.

time slows down as you attitude the fee of light. It stands to reason that the growth of the universe grew to become into quicker while it first began. So the passage of time could have been slower. of direction provided that we are on the in the universe, time might seem to be a relentless from our perspective whether it grew to become into rushing up or slowing down relative to in spite of exists previous its borders. So for all all of us understand the completed existence of the universe might desire to be one hundred billion years or the blink of an eye fixed. it extremely relies upon your viewpoint. temporal dilation is nearly a visit.

Why yes, it could, if it was to an observer outside moving at 99.9% of the speed of light.

yes,due to the galaxies,the sun,and the entire universe
