Why can't anything go faster than the speed of light?
I believe that an advanced civilization somewhere in our galaxy or other galaxies have developed and uses wormholes. Maybe they are visiting here today, observing our progress. To an advanced civilization we are a bacillus. There might be civilizations that can manipulate space and time. This is true of going through hidden dimensions. Remember, the Milky Way galaxy is 14 billion years old. Enough time for advanced civilizations to grow
It makes for great science fiction.
As for the longest possible age of a civilization, there could be no civilizations even existing in the first generation of stars. There were very few elements available for them to be made from initially. Many of the atoms from which we are made were either manufactured inside a star or in the supernova of a dying star. For example, even the simplest carbon based life-form could probably not have formed until the universe was at least three or four billions years old. Seven or eight billion years old would be more likely.
As for creating worm holes, it would be amazing if the most advanced possible civilization could create worm holes of any meaningful size in either spatial dimensions or in the time dimension.
It's strictly science fiction.

It has nothing to do with space rather C is more correctly defined as "the speed of massless particles in a vacuum". Which are forced to travel at this velocity as a result of not having any mass.

People like Carl Sagan has said its a possibility that advanced forms of life exists in the Universe.
And that was based on a Drake's equation decades before we had any idea how many exoplanets might really exist. So while the chances are the same, our calculations have suddenly become far more optimistic.
However as far as we are aware, the known laws of physics that in aggregate *are* our universe by definition must apply everywhere. They may be wrong, they may need adjustment, there may be places where they are...bent but that's due to a lack of knowledge on our part. Several things we hold in exceedingly high confidence however, such as the max speed. Sure, somewhere out there may be a civilization that's been around for tens of millions of years. And their understanding - and ability to manipulate - how our universe works may be vastly advanced. But the chance of them finding us at this moment in our history are exceedingly slim, enough so that we shouldn't wait for them.

Sure. But did he say that they can do the impossible?
This thread is a testament to how many annoying conundrums and fruitless mental struggles Humanity could save if nerds like Albert Einstein were routinely bullied out of any inclination for science before they could make a career on it and dictate whimsical things like nothing can travel faster than light ![]()

There are things that we still do not understand in the Universe. Maybe 100 years from now, in the year 2115, we would have a different understanding of the Universe physical laws. We still do not know what new physical laws might come up. Some may be invalidated. It is lighting a match in a dark room. We can't see what wonders or terrors await us in deep space. Remember 110 years ago, the technology was rather primitive. We were still using the horse and buggy.
And yet a lot of people would say that technological level was quite enough, thank you very much ![]()

Are you serious?
I believe by the year 2050 or 2060 we would have the ability to travel out of our solar system. If you are into conspiracies, some people think that we have the technology.
One possibility is that empty space is composed of small units or cells.
Light can occupy one of these units at a time.
This would allow a light source to be seen from every possible direction.
https://van.physics.illinois.edu/qa/lis ... s-light-go
In a universe where empty space is merely empty space there would be an infinite number of directions so it would not be possible to detect light from every possible direction.
The speed limit of light could be explained by the fact that one unit of light takes a certain amount of time to transfer itself from one cell of 'empty space' to another.
Time dilation also fits into this model nicely, each cell of empty space makes time go forward for each atom or unit of light it contains,
so these cells only do 2 things,
1 move energy or mass from itself to a neighbouring cell, and
2 make time go forward for the thing it contains.
The faster something travels, the more time slows down because each cell can only devote enough processing power to each of its 2 tasks.
So we are living in a computer simulation.

What about the head lights? Did you turn the head lights on?

Technology in the future may us allow to surpass that.
Not the lifetime of anyone alive today. Wont even be equaled in that time.

The pedant in me wants to point out that 110 years ago we were doing 75+ mph & could cross the USA in 3.5-4.0 days. We also were floating about in both lighter and heavier than air craft.
While such an upheaval as you describe might happen a century or five from now, the basic tenets of science require us to grant such wild suppositions the same truth and validity as any other possible future event that has no proof or indication of probability to back it. In other words, it is literally equal in possibility to pigs flying that we may discover how to move faster than light. Note that I'm not saying we won't someday *travel* a distance and get there sooner than light starting at the same instant from an outside time frame...
