How Many Fundamental Constants Does It Take To Define Our Universe? (Synopsis)

“The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal.” -Aleister Crowley As we learn more and more about the Universe, we’d like to describe it … Read moreHow Many Fundamental Constants Does It Take To Define Our Universe?

New supernova results: is the Universe not accelerating? (Synopsis)

“Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my luck and instead will spend my life trying to find flaws in this understanding – such is the role of a scientist.” -Brian Schmidt Just a few days ago, a new paper was published in … Read moreNew supernova results: is the Universe not accelerating?

Are The Beginning And End Of The Universe Connected? (Synopsis)

“What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as earth and ice, water, fire and air, a quintessence, pure spirit, resolving into no constituents.” –Jay Griffiths At the earliest times, we can trace the history of our Universe back to an inflationary state, where the energy … Read moreAre The Beginning And End Of The Universe Connected?

Could Dark Energy Be Caused By A Reaction To What’s In The Universe? (Synopsis)

“Another very good test some readers may want to look up… is the Casimir effect, where forces between metal plates in empty space are modified by the presence of virtual particles.” -Gordon Kane If you ask what the zero-point energy of space itself is, you can sum up all of the quantum fluctuations you can … Read moreCould Dark Energy Be Caused By A Reaction To What’s In The Universe? (Synopsis)

Ask Ethan: Will The ‘Great Attractor’ Defeat Dark Energy? (Synopsis)

“We detect motion along this axis, but right now our data cannot state as strongly as we’d like whether the clusters are coming or going.” -Alexander Kashlinsky When dark energy was discovered, and the expansion of the Universe was shown to be accelerating, there was concurrently another puzzle that received much less attention: the problem … Read moreAsk Ethan: Will The ‘Great Attractor’ Defeat Dark Energy? (Synopsis)

Could Dark Energy Be Caused By Frozen Neutrinos? (Synopsis)

“If you’re puzzled by what dark energy is, you’re in good company.” -Saul Perlmutter The accelerated expansion of our Universe was one of the biggest surprise discoveries of all-time, and something that still lacks a good physical explanation. While many models of dark energy exist, it remains a completely phenomenological study: everything appears consistent with … Read moreCould Dark Energy Be Caused By Frozen Neutrinos? (Synopsis)

Ask Ethan: Is the Universe expanding faster than expected? (Synopsis)

“Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.” -Adam Riess Just thirty years ago, scientists argued over the value of the Hubble … Read moreAsk Ethan: Is the Universe expanding faster than expected? (Synopsis)

How Would Our Universe Be Different Without Dark Energy? (Synopsis)

“We’ve known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make … Read moreHow Would Our Universe Be Different Without Dark Energy?
