No, gravity works like drag for object with mass, including space. For light it only changes its path, as space itself is being draged around gravity. There is interaction.
For that reason I think space is itself not a massless medium.
No…I said gravity slows time and gravity slows time. This is basic college level science. Sorry, but its frustrating arguing science with people who think they understand it…
“Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.”
“Because the strength of gravity is weakening with every step you take up a flight of stairs, the rate at which time proceeds is also speeding up with every step. People who work on the bottom floor of a skyscraper are literally time traveling into the future compared to the people who work on the top floor. But the effect is very small. So small, in fact, that you will never notice the time difference in everyday life. People who live and work farther away from the surface of the earth are only fractions of a nanosecond ahead per year compared to those close to the surface. Though small, the time rate difference between different altitudes is real and has been measured experimentally using very accurate atomic clocks. The U.S. National Institute of Standards and Technology (NIST) has measured such small time rate differences and published its findings. NIST was able to measure the small time rate difference between a point on the earth and a point half a meter higher, by simply raising their experimental table a half of a meter. Their findings matched well the time dilation predicted by Einstein’s relativity.”
This definition is only written as such because its basic thing, while in reality you cant understand how to calculate using only system of relatives, a neverending process is taking place, that leaves traces embedded in it. While it does so, you call the process time. Its happenings in space all along, tho. Memories you can have are changeable as is everything around, This is why everything corrodes, memories fade, its process due to constant movement, not due to passing of time.
What you experience as time can be limitlessly stretched and compressed. Its space and speed of changes. When its stretched, you stretch with it.
It truly limitless. You can experience it right now, only on human pace recorded by mind. That pace, that frequency gets lost eventually and something else replaces it.
Well, you might not be able to understand it but scientists do. The laws of thermodynamics and entropy are actually some of the oldest laws of science.
I find it pointless arguing over stuff that anyone can look up on the internet on any good science channel.
Even when you have equation of einstein, you have c as speed of light being described by relative speed of interaction, its not time in that km/s speed, its speed in a system of relatives. You can always replace it with some other number and equtions will have sense. Scale of speed changes. Why do you think “time” passes slowly when near light speeds? Its because of system of relatives that you are in, that dictates your perception of interaction.
The speed of light is always the same in all inertial reference frames. That is what makes everything else relative. As the speed of light is always measured the same regardless of whether you are moving towards it or away from it…something has to give in order to explain this. And that something is time and scale. Relative to a stationary observer, a moving object’s time slows down and its scale becomes shortened.
A strong gravitational field has the same effect. Which is not surprising as gravity is mathematically equivalent to acceleration ( Einstein’s principle of equivalence ). Strictly speaking the gravity and the slowing of time are one and the same thing…its not really a case of one ‘causing’ the other. This is why you will often find scientists making the statement that ‘gravity is not a force’.
I still enjoy the old Bob Lazar interviews about his experiences at S-4. He’s totally straight faced when he says, and I’m paraphrasing, “Their engines are 100% efficient. Yes that violates the laws of thermodynamics. No I can’t explain why because that should be impossible.” Guy passed a lie detector test when questioned about his stories, so he’s either the best liar in history or there’s ways to circumvent the laws of physics. 
Way over my head.
Its space and scale, not time and scale.
Its not time that slows down, it is space itself shortening. When you are moving in space, you are shortening space in front of you, you are interacting with it and you affect the system of relatives. From A to B is shorter than when you are stationary.
This is that “equation” that is completely analogue, not digital. You can probe it with some frequency, but its constantly going and going.
You have mind that works as digital medium, cells can be in state 1 and state 2. Its defined by cells inside brain.
While there is continuum to everything, you can probe it with different frequency, and that will in fact be constant you can then use in math, like that speed of light. But you can replace contant with another one, probed with different frequency. Everything have different pace then, can even happen instantly when you go to zero with probing. Or infinitely when you go to infinity with density of probing.
Time have only sense if you have mind and you are probing everything around you. Math uses it to ground everything around mind itself. Its entirely anthropomorphic view on the world. Same thing as we had with god, nature, etc.
Aliens can have different view.
An infinitesimal change in the independent variable corresponds to an infinitesimal change of the dependent variable.
Anyway, if you probe or not, the probed medium works the same, if you have concept of time or not.
“Time” doesnt move forward or backward, its system of relatives that is in movement everywhere in all directions. You could compress the medium by moving in certain direction. You say you probe it, and it shows you move faster, but its only because you have different lengths everywhere from the state of relative non movement. Length is what you measure, not time. Always. Now.
Distance, lengths being infinitely stretchable and compresable means we could even all live and die in a blink of an eye of another universe alien that would have different system of relatives.

No, that is complete nonsense. Why don’t you read up on actual relativity rather than spouting a misunderstood version ? It is readily available on the internet.
In actual relativity, time slows down and lengths shorten. No, space itself does not shorten…it is only the observed vehicle that shortens. Just because the vehicle is travelling close to the speed of light does not mean the distance to the nearest star will appear to have shortened.
Like I already said, it is pointless arguing over something that anyone can look up on the internet. Aaron’s video explains it all pretty well.
In actual world, there is no time, only lengths that shorten. Length is equivalent to space itself. When something shortens it compresses. Relative bodies affect space by changing lengths.
No, space itself does not shorten
Space is stretchable. What is stretching it is movement. It decompresses because there is constant pressure affecting it. When you have baloon, it will be bigger and bigger when you give the gas more energy and it will be stretching it from inside. The lengths will be bigger than they were before, but from inside it and in gaseous form you will not notice it. Frequency will be other from outside only.
it is only the observed vehicle that shortens.
Its lengths that shorten, and to become short they have to be compressed.
But while traveling the length to star shortens. The distance shortens. The vehicle being part of that distance also shortens.
Notice that what you think is time is only relative length. Length goes to zero for objects traveling with speed of light, but everything around it, not being that light path, have infinite lengths. Light will travel indefinitely while having zero length and with everything around having infinite lengths. It travels infinite lengths. Its journey is forever.
Well, to be honest human cant undertand such thing as forever or world without time, when no probing is taking place. Its not to be understood tho. Its to be.
One day I will be it all. 
This thread does not disappoint

I can’t believe you are still arguing even when you’ve been provided with articles and videos that explain it.
OK…so the whole of science is wrong and you are right. I give up. Beyond a certain point it is futile arguing with Dunning-Kruger.
No, it is not wrong, it is only presented from a different perspective. Different to what you may ask.
You’ve stated a load of stuff that is simply not scientifically true. Again and again I have endeavoured to correct you on it, and again and again you just argue.
For example you state “But while traveling the length to star shortens. The distance shortens.”
No, it doesn’t. The apparent length of the space-ship ( and only the moving space ship ) relative to an external observer shortens, but the external observer does not see the distance to the star shorten and neither does the traveller. The shortening is an effect of motion, and it is only the space ship that is in motion, not space itself.
All these facts are readily available on any good science site.
But if traveler starts in place A and after movement is in place B that is the goal of travel, that means that distance for traveler is reduced from point A to B, to zero. It is shortening. It is like space itself was compacted in direction of travel. Of course to do that traveler have to use force to compact the space. More force means that space is compacted more.
It is very complicated, and we dont notice it, but everything in our bodies constantly plays with space and energy, trying to sustain coherence. Compacting space too suddenly means that body desintegrates. We have limits we cant break. And in case of constructs, we can give them abilities surpassing our bodies, that means if aliens would be present and would have similar built bodies with such limits, they would use probes first, and last.
Nope…I’ve had enough. Read a science book.
@Altara_Zemara I watch youtube videos on this stuff and I seem to have more info on this then her

Gravity slows time…an effect that has been precisely measured even on earth as time runs imperceptibly slower on the surface that it does at the top of a skyscraper. This effect becomes hugely magnified near a black hole, to the point where at the event horizon time appears to stop relative to an external observer. It’s nothing to do with Einstein failing at the event horizon…it is an effect predicted by relativity.
Also, photons being timeless is basic science. It is a direct consequence of relativity, and is precisely why the speed of light is the same for all observers no matter what their speed relative to each other.
Not even wrong.
No, photons are not timeless because a blackhole consumes a photon.
A photon also has a short life of about three years.
Julian Heeck of the Max Planck Institute for Nuclear Physics set out the tackle this issue, and in research that was published in Physics Review Letters B, Heeck calculated how long photos can live at minimum.
Since photons are moving at such excessive speeds, time dilation comes into play and must be accounted for. Once this is taken into consideration, according to the photons frame of reference, Heeck found that its lifetime would be a rather short three years; however, from our frame of reference, light would live about one billion billion (1018) years.
I don’t think the one billion billion years is correct either, otherwise astronomers would still be seeing light from stars that went out one billion billion years ago that were relatively close to Earth before was a planet, but then again the Universe is only 14 billion years old and light would not have existed one billion billion years in the past.
