Nikola Tesla considered Einstein a fraud, and rightly so. Einstein's supposed theories were promulgated by TPTB in order to make humans believe that they are insignifcant, that their lives are meaningless. Believe that nonsense at your peril.

Re: Speed of light is so small compared to size of galaxy
A few billion years ago an ancient civilization (that the origin and history of is no longer known) built a large number of "wormholes" throughout the galaxy.

So although it's possible to go faster than light, it's not really necessary.

Why don't you know this?

They'll make us aware of this if disclosure ever happens.

Re: Speed of light is so small compared to size of galaxy
i'm not very knowledgeable on this but i think i have a very basic understanding.

the speed of light is relative, which means the speed of light always travels the speed of light, even if it is coming from something already moving at the speed of light... now you're going 2x the speed of light, if observing from the origin of that light.

sooo in reality the speed of light is infinite

that's my take lol

Light is SLOW!!!

This video shows a wonderful, graphic explanation, even though it's in the sci-fi realm, it's all we have to go by, but makes a good analysis.



But that's NOTHING compared to Hyperspace engines. Those will move you across the galaxy in mere seconds or minutes!

Just a trip to the closest star to Earth (besides our Sun) at some 4 light years away could be reached in only 14 seconds by the Millennium Falcon.

Excellent video on MANY things, not just spacecraft, here!

Re: Speed of light is so small compared to size of galaxy
So according to Einstein space is limited by the speed of light, meaning that would be the fastest we can go. one light year is 186,000 miles per second or 6 trillion miles in one year, essentially thats how much ground we can cover in on year. However considering the size of our galaxy milky way is 105000 light years and it would take us 26000 light years just to be out of the galaxy.. So meaning if we could go at our fastest potential speed it would still take us 26000 years to be out of this galaxy.. This is so upsetting how much knowledge and information is in the stars yet how unreachable it really is in retrospect.. heck people say we should reach for the stars, do they realize the closest star (not counting sun) is 4 light years away or 25 trillion miles away from us.

Re: Speed of light is so small compared to size of galaxy
for light to be a limit there has to be an ether otherwise there is no universal reference, and since an ether is highly unlikely the question when measuring velocity is how does it know. Velocity is relative to something and whatever your something light is always c, so I believe it is a characteristic of how it propagates. Relative to you c is observed in free space.
 Quoting: Anonymous Coward 77396442


It was discovered a few years back that the universal constant, isn't a constant. Both in Earth's history and in our observations of the universe around us, it is not constant.

Even the speed of light is different in different areas of the universe.

Re: Speed of light is so small compared to size of galaxy
At what speed the universe is expanding, investigations to date yield contradictory results. A new method of measurement was supposed to solve this conflict - it finds out: The truth is in the middle.

Astronomers have determined the expansion speed of the universe with a new method. However, the result does not provide the hoped-for solution to a conflict of previous measurements. The new value lies in the middle, as the team around Wendy Freedman reported in an upcoming issue of the journal "The Astrophysical Journal". If the discrepancy between the different measurements can not be dispelled, this could indicate an incompleteness in our model of the universe.

Since the Big Bang the universe expands. That's what the American astronomer Edwin Hubble discovered about 100 years ago. At the same time, the cosmos grows like a yeast cake: each raisin in the cake moves away from the others, and the faster the further two raisins are from each other.

The speed with which this cosmic yeast cake grows is called in honor of the discoverer Hubble constant. "The Hubble constant is the cosmological parameter that sets the absolute scale, size, and age of the universe," Freedman says in a statement. "It is one of the most direct ways we have to quantify the evolution of the universe." The exact value of the constants is, however, harder to determine than many astronomers had hoped.
Hard to measure distances in space

One reason is that distances in the vastness of space are difficult to measure. Researchers have developed different standards for this. A very proven regularly uses pulsating stars. The period of these so-called Cepheids is directly related to their luminosity, as studies have shown. The easy-to-measure period of a Cepheid star thus sheds light on how bright it radiates. "The comparison of how bright distant Cepheids appear with the brightness of near-Cepheids enables us to determine how far away the respective home galaxies of the stars are," explains co-author Barry Madore of the Carnegie Institution in Washington.

By studying Cepheids in other galaxies, astronomers have determined a value of the Hubble constant of 74 kilometers per second per megaparsec. The astronomical distance unit 1 Megaparsec corresponds to 3.26 million light years, ie the distance the light travels in 3.26 million years. A galaxy at a distance of 1 megaparsec is therefore 74 kilometers away from us every second, a double-distance galaxy twice as fast.

 Quoting: Anonymer Feigling


The team around Freedman has therefore devised a third method for measuring the Hubble constant. They used the Hubble Space Telescope to study so-called red giants in other galaxies. These are stars that swell to gigantic proportions at the end of their life cycle.

Red giants arise when a star has used up its main fuel, the hydrogen, and begins to burn helium. When helium burning ignites, this helium flash is accompanied by a reorganization of the star. Freedman's team took advantage of his analysis that red giants all shine brightly just after the helium flash. If one seeks out only red giants in this phase, the apparent brightness on the earthly firmament yields again their absolute distance, similar to that of the Cepheids. In this way, the scientists come to a value of 69.8 kilometers per second per megaparsec - and are thus between the other two methods.
