there was a bit more to Astronomy than looking through a Telescope even before!
Spectrum-Analyzers,IR and UV tells you more than just looking at it through even the biggest Telescope!

i agree,they have made amazing strides in the science, but the distance is so vast, even the best telescopes can't see everything...

Moe, many of the objects we are observing in deep space were predicted by math. A good example is Einstein's postulation on black holes which falls out of General Relativity. We now can see very clearly the black holes feeding and reacting gravitationally with other objects. Einstein hasn't been proven wrong yet. See how math led

Spend an hour watching this video. It covers many aspects of how science to where it is today. Time, universal expansion, time travel, black holes, big bang, big crunch, supernovi, red shift, etc., including the end of time and how it all fits together. Michio Kaku uses non scientific terms to explain it all.

Mentioned briefly is the concept of quantum time which would occur if at the time the big bang singularity acted as all other quantum particles act, that being able to be in more that one place at one time, would allow for multiple universes with multiple timestreams.

they don't explain what time is, and why it can dilate.. sorry, just can't see it...

the main reason they don't study time is because they know it doesn't exsist... nothing there to study... if thats the case, then how does nothing dilate? ... because math says so... when they actually find the physical reason of the dilation, then i can get on board with it...

maybe the molecular decay speeds up/slows down the faster something goes?

I don't know who you mean by "they". Time is an integral part of Einstein's Theory of General Relativity. It is one of the most studied and most empirically tested theories in science. One of the main concepts being presented in the video is that a massed particle at high speed experiences time at a much different rate than one moving at a slow speed. The fact that the decay rate was greatly lengthened is proof of the change in time due to relativistic effects.

Nothing like a brief moment when you look at the title to a thread like this one and read it as a physicians questions of light to change the meaning of a discussion and wondering why it was called that?

Maybe I'm just tired. But that did just happen to me.

they didn't test what time is, they assigned it a value, like an inch or a mile...thats how they tested the theory...

(they = scientists)

maybe the decay rate has more to do with speed than time, just a thought...

Well, if you did the math you would discover that the extra time it took the particle to decay matched exactly Einstein's Theory of Relativity.

thought moves at the speed of light, and believe it is possibly even faster

could you formulate this?

Present Telescopes cannot reach everywhere, however there is one thing that can. CertainTrained RemoteViewers
have the ability, and can reach and see what is at vast vast distances, this has already been done, in the Star Wars project in the US, and information has been recorded on what was seen. I am a remote viewer myself, but I am out of practice and I do not have that sort of talent and ability to do the vast distances, but I know how it can be done. If an astronaut was taken in somewhere in our solar system, we can already treat them using Radionics, that is no different to healing anybody anywhere on this planet. Standard Science and Physics is already been turned on its head. Physicist are now looking at the new Science of Noetics and are very excited about it, I too am doing research and development in this field and I can already do things which are supposed to be impossible, so we all have to open our minds.

yea, I'll have to watch that train go by for a few stops before i get on board...

What you are proposing is called Quantum-Woo,Pop-Science!
Definitely NOT a Science!

Our ability to measure is increasing exponentially. The sensor arrays in many instruments can detect a single photon of light.

A new study from Tel Aviv University reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature in radio waves which astronomers can now search for. The work is a major new finding about the origins of the universe.

"One of the exciting frontiers in astronomy is the era of the formation of the first stars," explains Prof. Rennan Barkana of TAU's School of Physics and Astronomy, an author of the study. "Since the universe was filled with hydrogen atoms at that time, the most promising method for observing the epoch of the first stars is by measuring the emission of hydrogen using radio waves."

The study, just published in the journal Nature, was co-authored by Dr. Anastasia Fialkov of TAU and the �cole Normale Sup�rieure in Paris and Dr. Eli Visbal of Columbia and Harvard Universities.

Cosmic archaeology

Astronomers explore our distant past, billions of years back in time. Unlike Earth-bound archaeologists, however, who can only study remnants of the past, astronomers can see the past directly. The light from distant objects takes a long time to reach Earth, and astronomers can see these objects as they were back when that light was emitted. This means that if astronomers look out far enough, they can see the first stars as they actually were in the early universe. Thus, the new finding that cosmic heating occurred later than previously thought means that observers do not have to search as far, and it will be easier to see this cosmic milestone.

Cosmic heating may offer a way to directly investigate the earliest black holes, since it was likely driven by star systems called "black-hole binaries." These are pairs of stars in which the larger star ended its life with a supernova explosion that left a black-hole remnant in its place. Gas from the companion star is pulled in towards the black hole, gets ripped apart in the strong gravity, and emits high-energy X-ray radiation. This radiation reaches large distances, and is believed to have re-heated the cosmic gas, after it had cooled down as a result of the original cosmic expansion. The discovery in the new research is the delay of this heating.

The cosmic radio show

"It was previously believed that the heating occurred very early," says Prof. Barkana, "but we discovered that this standard picture delicately depends on the precise energy with which the X-rays come out. Taking into account up-to-date observations of nearby black-hole binaries changes the expectations for the history of cosmic heating. It results in a new prediction of an early time (when the universe was only 400 million years old) at which the sky was uniformly filled with radio waves emitted by the hydrogen gas."

In order to detect the expected radio waves from hydrogen in the early universe, several large international groups have built and begun operating new arrays of radio telescopes. These arrays were designed under the assumption that cosmic heating occurred too early to see, so instead the arrays can only search for a later cosmic event, in which radiation from stars broke up the hydrogen atoms out in the space in-between galaxies. The new discovery overturns the common view and implies that these radio telescopes may also detect the tell-tale signs of cosmic heating by the earliest black holes.
