Let's take these one-at-a-time ...
-- Time doesn't 'stop'. If you shoot past Bob at high speed, and you and Bob look at each others'
clocks as you pass, Bob will say that his clock is running normally and yours is running slow, while
you will say that your clock is running normally and Bob's is running slow. You'll both be correct.
If you were moving past Bob at the speed of light, Bob would say that his clock is OK and yours
has stopped, while you would say that your clock is OK and Bob's has stopped. Again, you would
both be correct.
-- You don't reach the speed of light.
-- Within a certain distance of a black hole, light can't escape.
(That's why the region looks black from outside of it.)
The light trapped in there is still moving at the speed of light.
But nothing else in there is moving at the speed of light.
This is not what I was asking and is incorrect (I edited my question for clarity). It is motion that is relative. Bob can claim you are moving or you can claim Bob is moving and both are correct. Time is different if you speed up you move through space faster thus you move through time slower. If you traveled at speeds near the speed of light for years when you returned to earth the people on earth would have aged more than you. Space and time are part of the same fabric. Once you reach the speed of light time stops because you are moving through space as fast as you possibly can thus there is no room for you to move through time. When it comes to the distortion of space time velocity and gravity are the same. If you are in a place with high gravity time slows down. So if you are in a black whole which has enough gravity to over power light which time stops at, does time go in reverse inside the black hole.
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Mass and velocity are dimensionally different. They cannot be added.
At the point of the event horizon, the pull of gravity is so strong that the escape velocity reaches the speed of light. As such, when light reaches this point, it cannot escape.
This state is known as terminal velocity. In it's current shape, an object as described cannot travel any faster. The force of gravity is constant where as the force of air resistance increases with velocity so it takes time for an object to reach its terminal velocity.
Gravity and magnetism are inherently different forces. One cannot be the other.
Its chemical property.
You cannot fall faster than maximum velocity. However, maximum velocity is reached when drag force has increased to the point that gravity can no longer accelerate the body. If drag can be reduced, maximum velocity is increased. If the body is falling where there is very little drag, such as very high above Earth, the body will continue to accelerate until the atmosphere that has been reached is more dense and the drag has increased, thereby reducing maximum velocity. This was demonstrated by Felix Baumgartner in the free fall 24 miles above Earths surface, when he reached a speed of 833 miles per hour prior to entering the dense atmosphere.
gravity is a force that defines terminal velocity, along with friction and others..objects can only fall so fast due to friction..on earth gravity pulls at 9.8m/s2 while at the event horizon of a black hole gravity pulls faster then the speed of light, which is why light cannot escape it
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Gravity cannot be smelled.
No. Gravity cannot be seen.
You cannot because a number has no velocity.
Mass and velocity are dimensionally different. They cannot be added.
It cannot have negative velocity, it can have negative acceleration.
The gravity of the situation cannot be overstated. Don't let gravity get you down!
No. We cannot alter gravity.
