The Universe is all of spacetime and everything that exists therein, including all planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. Similar terms include the cosmos, the world, reality, and nature.
The estimated diameter of the observable universe is about 93 billion light years or 28 billion parsecs. Scientific observation of the Universe has led to inferences of its earlier stages. These observations suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history. The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe, which is calculated to have begun 13.798 ± 0.037 billion years ago. Observations of supernovae have shown that the Universe is expanding at an accelerating rate.
There are many competing theories about the ultimate fate of the universe. Physicists remain unsure about what, if anything, preceded the Big Bang. Many refuse to speculate, doubting that any information from any such prior state could ever be accessible.[citation needed] There are various multiverse hypotheses, in which some physicists have suggested that the Universe might be one among many, or even an infinite number, of universes that likewise exist.

I love when he says: Hell break loose….hell yeah
If everything is expanding away from everything else, how is it that galaxies collide?

The further things are away from you the faster they move either towards you or away from you… This proves the universe is expanding? Ok so then when things get closer to us they slow down because logic? Things in motion stay in motion in space until acted upon by something. Just because something is further from you doesn't make it move further from you any faster.
I'm a Plasma Theory supporter. And this stupid playground flawed logic is what is suppose to stop us? Its your hard evidence? Can you not put 2 + 2? I saw it right away learning something new and immediately pointed out this flaw. I don't think people actually research what they use as proof…
Hold on… wait a second… The part where they were talking about the calculable probability that a human can be dissolved and re materialized somewhere else. I think that may have happened in history before! If you have ever heard of the story of the Spanish soldier who took a nap and woke up in the Philippines hours later, then you may know what i mean. But then again could a human survive such an event?
A body become so small when its volatile components such as water, air and heat get released as a process of death leaving only pure element of earth. This is the process called black hole. BH consuming objects in its path is illusion, otherwise where are the excrement?
The atom is made up of what is called dark matter and the force keeping it together is dark energy. What causes it to expand after contracting and contract after expanding is density. There is an impersonal process of trying to equalize the distribution of particles, which follows exactly the same process of temperature and atmospheric pressure equalizing. It is also the same process of evaporation. Once the density has become so hard in relation to its surrounding it will explode, which is the big bang if it were the universe. As the fragmentation revolves it collect the particles that would characterize it existence. These particles are the dark matter. Time will come when the life span of the bodies – particles if it were an atom – would come to their end and would seek the center of the mass to form a singularity. In the process, the bodies would release the particles that constitutes them, which are referred to as dark matter. The process is called black hole.
This program was SEVENTEEN YEARS old when it was posted as a "New NOVA" program in 2015. It isn't even a NOVA program, it is one of five episodes in a PBS series titled "A Science Odyssey" in 1998.
I regret that I have but one thumbs down to give.
Although the title is slightly deceiving in that it appears to promise a new documentary I am happy to give this older, yet still amazing, film a thumbs up for the content alone. I am a fan of today's most popular universe based documentaries such as How the Universe Works and The Universe, but this is not like those. It looks deeper into the lives of some of our most famous astronomers and physicists from the past 2 centuries revealing more than just their brilliant theories. It has a good blend of the science and the personality of those they focused on such as Hale, Hubble, and of course Einstein. Definitely a worth while documentary for anyone interested in these topics and people.
why are these videos such crap quality all the time
I wanna penetrate the essence of Amy Mainzer 🙂 I believe in the philosophy of Pizza Steve from Uncle Granpa!
Thanks for the dreams , so beautiful , what a trip, what a high. The universe is so mysterious. I think if I come back I don't want to be a rock star, rather a astrophysisist. It is kind of spiritual. am blown away. Great stuff.
