Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don’t have all the answers yet so let’s talk about what we know.
Also, we try to make this one not depressing. Tell us if we succeeded.
BY THE WAY. We have a website now. We’ll try to blog from time to time, show you guys how we make the videos and give more insight to our process. Also we sell stuff. We really don’t know where this whole kurzgesagt stuff leads us. But we are really thankful for all the attention and positive feedback and yeah, maybe we can make this our jobs — it would be pretty nice and we could do more content each month. But we’ll see. For now, thank you very much everybody for making this little adventure possible.

Thomas did an aweful good job again. 🙂
Next Video: April. (as soon as we can but we kind of have to make a living and visit college) Topic: Nuclear Energy (probably, if we finish the research in time — if not something else)
Short videos, explaining things. For example Evolution, the Universe, Time, the Stock Exchange or controversial topics like Fracking. Because we love science.
We’re a bunch of Information designers from munich, visit us on our website, twitter, facebook or behance to say hi!
Scientists have traced a unique new map of the first light of the universe, and raised profound questions about the Big Bang.The image of the cosmic microwave background they have released was taken by ESA’s Planck satellite, and its results could have a significant impact on the field of cosmology.
“It turns that most of this image, most of this map, fits beautifully our very simple model. At the same time we find some strange things, and this is where it starts to get interesting, because we see some signs of things that do not fit,” explains ESA’s Planck Project Scientist Jan Tauber.
“Roughly speaking the things that we are finding that are not as we expect are features that are across the whole sky. When you look only at the large features on this map you find that that our best fitting model, our best theory has a problem fitting the data, there is a lack of signal that we would expect to see,” he says.
The news that the early universe is not quite as was thought has left the greatest minds in cosmology spinning with excitement.
George Efstathiou, Professor of Astrophysics, University of Cambridge, is a key member of the Planck Science Team.
“The idea that you can actually experimentally test what happened at the Big Bang still amazes me,” he says.
The Big Bang theory remains intact of course, but the concept of inflation could be put to test by the Planck data.
“We see these strange patterns that are not expected in inflationary theory, the simplest inflationary theories,” explains Efstathiou.
“So there’s a real possibility that we have an incomplete picture. It may be that we have been fooled, that inflation didn’t happen. It’s perfectly possible that there was some phase of the universe before the Big Bang actually happened where you can track the history of the universe to a pre-Big Bang period.”
The Planck mission could test ideas about how the early universe was formed.The puzzle is that at small scales the data fits the theoretical model very nicely, but at larger scales the signal from the cosmic microwave background is much weaker than expected.
Efstathiou is looking for answers: “Can we find a theoretical explanation that links together the different phenomena that we have seen, the different little discrepancies, with inflationary theory? That’s where there’s the potential for a paradigm shift, because at the moment there’s no obvious theoretical explanation that links together these anomalies that we have seen. But if you found a theory that links phenomena that were previously unrelated, then that’s a pointer to new physics.”
It appears that the audacious Planck mission really will shed new light on the dawn of time.
Acquired by ESA’s Planck space telescope, the most detailed map ever created of the cosmic microwave background — the relic radiation from the Big Bang — was released today, revealing the existence of features that challenge the foundations of our current understanding of the Universe.
