Ways The Universe Could End
We all know the theory surrounding the early development of the universe thanks to the cosmological model of this development called the Big Bang Theory. With the age of the universe pinned at 13.798 billion years ago, the universe has been around for an extremely long time.
There are many theories on how the universe will end or maybe it will never end and will continue expand forever. Dark energy, the equation of state and the shape of the universe all play a role on the fate of the universe.
Check out our latest video which goes over ways the universe could end!
Gravitational Wave Discovery! Evidence of Cosmic Inflation
Baby photos of our universe show huge early growth spurt!
- The lengthening of wavelengths is not strictly due to stretching by the expanding universe but by the way the photons were emitted and absorbed in different frames of reference.
- The effects of gravitational waves have been observed in the decaying orbital periods of some binary star systems, however detectors built to measure gravitational waves stretching and squeezing matter on Earth have not as yet detected them.
- In the video I sometimes use the term Big Bang to refer to the beginning of time as we know it. The Big Bang actually refers to the whole process from the formation of our universe, through inflation, to the expanding mass of plasma in the early universe (not just the first instant).
- Quantum gravity is by no means established by this observation but it is suggestive that General Relativity and Quantum Mechanics are working together here.
Thank you to Professor Geraint Lewis and Henry Reich for comments on earlier drafts of this video (even if I haven’t accepted all of your corrections).
What is the universe made of?
The atoms around you have existed for billions of years — and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms’ long journeys from the Big Bang to the molecules they form today.

How Big Is The Universe?
Beakus were commissioned to create three animated films that explain key concepts about our universe, with humour helping to explain the ‘almost’ unexplainable! Director Amaël Isnard also designed the films.
In ‘How Big Is The Universe?’ ROG astronomer Liz shows us the expanding nature of the Universe and how this affects the light reaching us from distant galaxies, some of which will remain forever hidden from our view.

The Countdown №44 - 5 Essential Facts About Gravity Waves from the Big Bang
On March 17th, physicists with the BICEP2 experiment announced they had detected the remnant of gravity waves in the cosmic background radiation, the light left over from the big bang. While still needing confirmation, the discovery lends weight to the idea that the early universe underwent rapid expansion.

What Is The Cosmic Microwave Background Radiation?
The Cosmic Microwave Background Radiation is the afterglow of the Big Bang; one of the strongest lines of evidence we have that this event happened. UCLA’s Dr. Ned Wright explains.

Why Is This A Special Time For The Universe?
You might be surprised to know that you’re living in a very special time in the Universe. And in the far future, our descendent astronomers will wish they could live in such an exciting time Let’s find out why.

Stanford Professor Andrei Linde celebrates physics breakthrough
Detected primordial gravitational waves! See how looks the excitement of a big discovery in scientists, or more precisely, the emotion after experimental evidences about a theory, inflation theory, over one of the fathers of it. Assistant Professor Chao-Lin Kuo surprises Professor Andrei Linde with evidence that supports cosmic inflation theory.
- Primordial gravitational waves are gravitational waves sent out into space a trillionth of a second after the Big Bang. They could have been detected by analyzing the polarization (B-modes) of the cosmic microwave background.
- Announcement at Harvard-Smithsonian Center for Astrophysics.
- BICEP and Keck Array (BICEP2 2014 Results Release)
- Sean Carroll pre-announcement and update.
- Liam McAllister (Cornell University) at The Reference Frame.
- WIRED: Cosmologists Finally Capture an Elusive Signal From the Beginning of Time.
When a big discovery means a lot. I love seeing scientists as emotional human beings. This is a part of the story that is often left out of the press releases and news stories.

Was the Universe Designed?
A contentious question, especially given recent debates between a certain science guy and a certain creationist. Is there any strength to be found in the Teleological argument, or its fraternal twin the Fine-Tuning augment?
