Carl Sagan, the famous astronomer said it first and was right."We are made of star stuff". In his video, Carl Sagan descibes evolution. We know that Carl Sagan was right because when astronomers point their telescopes at the stars and use a prism to break down light it separates the light into different colours, but more importantly, each element being fused within the star, absorbs the light at different wavelengths.

These absorption lines appear as vertical lines between the colours of the spectra and are different for each element.  This is illustrated below.

So when these light spectra are coming from stars, astronomers know which elements are being fused in each star.  This gives each star a particular signature of elements.

The thing is, no matter where astronomers point their telescopes the variety of elements that are interpreted, the same 92 elements of the Periodic Table are revealed.

Material is spread throughout the universe via supernova explosions of dead stars, which recombine and recycle this matter into new stars which explode again.

This simple and amazing fact indicates that the mass of all the stars in the universe are made of the same star material that we find on Earth. 

As all life on Earth is carbon-based, we are also made of the same material.

Listen to Neil DeGrasse Tyson expalin this.

So you see, Carl was right.

"We are all made of Star Stuff".

Ever wonder how astronomers know the composition of distant stars, galaxies and nebulas? It's easily done by breaking down the light from these distant objects using a prism. Different elements produce different sprectra, so star light can be broken down too.

Here is a video that explains how we know the composition of every star and galaxy at which we can point a telescope.

Here is a great vdeo from Dr. Brian Cox who explains how different elements give off different light spectra and absorption spectra. It is the dark bands of absorption spectra that are the codes for the elements being fused in each star.

By interpreting light sprectra from all the stars in the sky, astronomers have determined that they all contain the same 92 elements found on Earth!

In other words, we are all made of the same "Star Stuff". This links the Earth and all life as we know it, to the rest of the universe.

Astronomers can also use light spectra to determine a star's temperature, distance and they can tell if it is moving away from Earth or moving towards us.

This is light physics at its best.

Worm holes are theoretical concepts that are calculated to exist only in Einstein's equations of special relativity.  They have never been observed directly or indirectly, but if they do, they are considered to be immense distortions of space, possibly having a black hole at one end and white hole at the other. Worm holes are the doorways between two areas of space and time that are so extremely distorted, that they are folded like a sheet of paper (below).

In this video, astronomer Ian Morison discusses how a worm hole could act as a theoretical time machine (assuming humans can ever develop technology to travel at 99.999% of the speed of light and assuming we could survive a trip through a worm hole. Dr. Morison is illustrating Einstein's Theory of Relativity quite nicely with this analogy. 

Right now, travelling through a worm hole is pure fantasy, but not too long ago, the scientific community was saying the same things about black holes, which now are scientific fact.

Good video that describes the basic theory of black holes, how they form and how they are thought to distort space and time.

Distortion of space and time at a black hole are theoretical of course, and it is unlikely that we will ever get direct measurements of anything at the edge of a black hole because of its destructive power and the immense distance to the nearest one.

However, it is awe-inspiring to know that black holes exist.

Worm Holes are theoretical passage-ways through spacetime.  They exist only in the equations of special relativity by Einstein (Einstein-Rosen Bridge). It is known that massive objects with immense gravity warp space-time. This has been proven by observations (i.e. extremely accurate satellite clocks in orbit around the Earth are known to be consistently picoseconds faster than the same clocks on Earth).

Therefore as one gets closer to extremely large objects, space is warped and time slows.  This is exaggerated millions-fold when a Black Hole is approached.  It is theoretically possible for space to be warped so much that it can be bent over on itself like a sheet of paper.

Consider space is like a sheet of paper that is bent forming a "U". A black hole at one side of the sheet of paper can connect with the opposite "White Hole" on the other side. This connection can be considered a Worm Hole through space-time (below).

This is a great video explaining the concepts of Black Holes and Worm Holes.

So Worm Holes are currently possible only in theory.  However, the same was true for Black Holes only a few years ago, and today, Black Holes are science fact. They not only were calculated by Einstein to exist, but their interaction with matter has been observed and has been documented. Who knows, the same may be true of Worm Holes in the future.
