I have theorized that movement in space is relative to other objects by itself it is standing still as long as a force does not change its direction according to Isaac Newton. Everything inside a moving object is standing still with its surroundings traveling the same direction. Like a fly in a car traveling 70 miles an hour on the freeway. To the fly his surroundings are standing still. That is the same thing we experience on earth. Our planet is moving in several directions at tremendous speeds. But as far as we are concerned we are standing still.
When you see someone drop a ball from the
mast to the deck on a moving boat, the ball falls directly to the deck under
it. But if you watched from the shore the ball would appear to move at an angle
moving with the movement of the boat.
However, if we change speed in any
direction there is inertia. If a jet plan were to stop suddenly the pilot would
be splattered against the inside of the front of the plane. Or suddenly jump to intense speed it would
produce the same effect in the opposite direction.
So if a spaceship were to increase speed continually
steadily by using power from solar, or unknown energy source outside of the
craft it could continually increase speed. The slow continual acceleration reaches
until speeds faster than light, then it could reach infinite speed and reach
another planet or galaxy in a short time. Half way there reverse and decelerate
at the same rate.
However, the things inside of the space
craft would have to withstand the continual acceleration and deceleration.
But what about helium? It reacts the
opposite of gravity in a car under acceleration and deceleration. It it
antigravity?

When you accelerate and decelerate your
car, you feel yourself getting pulled back and forth. As Isaac Newton explained
350 years ago, a body at rest or in motion tends to stay that way until
acted upon by an outside force. So motion is only relative to another object
moving in a different direction. So let's say you're driving forward at 40
miles per hour and you accelerate to 55 mph, feeling yourself pressed back into
the seat. What's actually going on is that your body wants to stay at the
constant speed of 40 mph but the car starts going faster than that, catching up
to you and pushing you forward then you accelerate with the car. As for
helium when you accelerate a bunch of air molecules are forced backwards also.
This sets up a tiny pressure gradient, with slightly denser air at the back of
the car and slightly thinner air at the fore. This is why the balloon rises
"upward" through the thicker air at the earth’s surface to thinner
air above just like a bubble of air in water.
Here is proof that it is the density of
the air around the balloon that causes it to go forward in a car when it
accelerates, and backwards when you decorate the opposite of what you would
expect. He is proof this helium balloon is hovering in normal air in a bell jar,
but when the air is pumped out the balloon falls to the ground in the vacuum.
