How Far Away is the Sun? Another Visualization. - Brad BlogSpeed Alright, this one’s a doozy. After the reasonable popularity of last week’s scale picture that illustrated the distance between the Earth and the Moon, I just had to take things to the next logical level. Today I’ve reduced the scale, and increased the image size dramatically, to represent one astronomical unit (AU), or the distance between the earth and the Sun. Frequently Asked Questions in Cosmology Tutorial : Part 1 | Part 2 | Part 3 | Part 4 | Age | Distances | Bibliography | Relativity What is the currently most accepted model for the Universe? The current best fit model is a flat ΛCDM Big Bang model where the expansion of the Universe is accelerating, and the age of the Universe is 13.7 billion years. Back to top. What is the evidence for the Big Bang? The evidence for the Big Bang comes from many pieces of observational data that are consistent with the Big Bang.

The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush. Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water--20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth--Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over--20,000 times over. The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together. The new cloud of water is enough to supply 28 galaxies with water.

Future - Science & Environment - Drake equation: How many alien civilizations exist? Are we alone? It is a question that has occupied mankind for centuries. Today, we live in an age of exploration, where robots on Mars and planet-hunting telescopes are beginning to allow us to edge closer to an answer. openfootage Astronomical &Nightscape Photography by Chris Cook Last Update: December 12, 2015 All the images in this site are © Copyright 1987-2015 by Chris Cook.

The Massey Experience Welcome to The Massey Experience, an online exploration of the ideas, themes, theories and characters that form Neil Turok's 2012 Massey Lectures The Universe Within: From Quantum to Cosmos. The Massey Experience is an immersive, evolving companion to Neil's Massey Lectures which aired on CBC Radio's IDEAS in November 2012. The story is a journey from quantum to cosmos: where we've come from, where we're going and what we've learned along the way. Neil argues that we're on the cusp of yet another major transformation: a coming quantum revolution that will supplant our current digital age. It's the story of science and technology, but it is also the story of who we are: amazing creative humans. You can also explore the Massey Lectures by purchasing The Universe Within from House of Anansi Press.
