Good documentary but will be better if the music is toned down or eliminated altogether. I'm interested to hear what the narrator is saying, not what the band is playing. I really hope that the makers of these documentaries listen to our complaints about the background music being too loud - thank you.

The music is way too overwhelming and distracting for a documentary that I’m supposed to “fall a sleep to”. I cant focus on what’s being said. It’s overwhelming to fall asleep with this playing.

When are we going to deal with the space junk and old craft we have up there? Eventually it will become a major problem for future satellites and space vehicles.
but isnt your red blue green yellow map of the universe messed up? things closer that are still burning(shining) will converge with light from farther stars. and hit your scope at the same instant?? making some stars seem brighter and many wont even be in the right area, due to mass bending the light.
@@KeystoneInvestigations I looked it up. Everything dies. To many, this seems to be the one absolute truth to the universe: Plants and animals rot and decay, stars explode and grow dark, planets crumble or are burned, and even black holes may radiate away. Indeed, our very atoms, which are the same atoms that make up everything else in the universe, decay into lighter elements as time marches on. But what about light? Can it die, or will it exist for infinity? In order to understand the answer to this question, you need to understand how atoms work. Fortunately, in a previous article, we covered the life of atoms (so head there if you want a more comprehensive discussion of how atoms change). But in short, anytime that you have a heavy atom, there is some risk that it will spontaneously start to break down into smaller particles. This is known as “radioactive decay," and it is the process that ultimately leads to the demise of atoms. But does a similar process work in relation to light? Sun Electromagnetic Radiation The Sun emits radiation almost all across the electromagnetic spectrum (Image of the Sun courtesy of NASA) Ultimately, this question hinges on whether or not photons (the carriers of the electromagnetic force, i.e. light) can have mass. Typically, photons are said to have zero mass. This is the standard solution that is accepted by a majority of scientists (in other words, it is the scientific consensus); however, as always seems to be the case in science, things get tricky when we start adding other variables and thinking about the "what ifs." For example, what if photons did have mass? If a photon did have a non-zero rest mass, that means that it can decay into lighter elements, so the photon would breakdown into either some known elementary particles that are lighter, such as a neutrino and antineutrino, or an as-yet-undiscovered-particle. Notably, the problem with this idea is that, according to our current understandings, photons cannot be brought to rest. As a result, the idea of rest mass does not really apply to them. But for the sake of physics, let's assume that photons do have non-zero rest mass. Thanks to previous experiments, we know what the upper limit of this mass is, so taking this into consideration, how long can photons live? 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. That looks a little something like this: 10,000,000,000,000,000,000. For comparison, the universe is only 13,800,000,000 years old. Notice the great disparity in those numbers? Well, this excessive gap means that, for all intents and purposes, the photon lives forever. In order to come up with the figure, as previously mentioned, Heeck needed to know what the upper limit rest mass is for photons. Thanks to previous analyses, Heeck had a figure that constrained this to 10-18 eV (10-54 kg). Then, Heeck used the spectrum for the Cosmic Microwave Background Radiation (CMB), which is the most precisely measured black-body spectrum in nature, to complete his research. If the photon does have mass, and it can decay into lighter particles, the number density of photons in the CMB should decrease as the photons travel. By utilizing a combination of the known constraints for the aforementioned mass and the CMB constraints, Heeck's analysis showed that a visible wavelength photon is stable for, as you already saw, at least 10,000,000,000,000,000,000 years.
An outstanding look at our cosmic backyard!
Weird we know more about the contents inside the Sun then we do the depths of the oceans on earth.
Great comment!

Still applies!
so wouldnt some of those empty spaces possibly have stars in it.????
Way too many sound effects and music, please just get back to documentaries and not the theatrics!
Way too many negative comments from you….sort your attitude out.

So a photon is forever? They don't run out of energy in 13.8 billion years?
No.....basic laws of physics!
