Dr. Adam G. Riess is a Professor of
astronomy and physics at the Johns Hopkins University and a member of the
Committee of Science at the Space Telescope Science Institute in Baltimore,
Maryland. He proposed a series of discoveries in the field of cosmology. So in
the year 2011 was awarded with the Nobel. Together with his team, they showed
that the universe is expanding at one ever increasing speed. The universe is
huge and full of galaxies, so it seems to be static, but it is not. The
separation of galaxies ever increases more and more. His research includes
measurements of the cosmological framework with supernovae. These measures,
showed an improvement in the ability to distinguish between a dark energy
constant, dynamic static and cosmological.
Expected that the universe downturn
under the gravity brake applied by its own mass, so this was a huge surprise. An
amazing reason was because the attraction of all the matter in the universe
should act as a retainer natural expansion. Therefore, the rate of growth of
the universe should be decelerating. There are three possible reasons given by
Dr. Riess: power vacuum, dynamic dark energy and relative gravity, showing the
otherwise in Einstein's theory. What began to ask different questions, how old are
the universe and the Earth.
In the end, it seems to me that
there is still much to discover. This was a step forward in science, but this
is a too varied range and great discoveries still wait. I thought it was a very
interesting conference and was a privilege for us as a University that Dr. Riess exposed the research with us. All
of this for me is something new, so I learned the main reason for the conference:
the universe is expanding, totally new concepts to my knowledge and the photos
that he showed. On the other hand, it is interesting to see how as the years
pass still continue questioning theories such as the Einstein, but it is as Dr.
Adam Riess mentioned in the
presentation: "If Einstein was wrong, why not us?" I think that all
of us should be like the universe. We must continue to expand our knowledge and
discover new galaxies which in this case would be our future experiences. These
experiences will lead us to discover more about our internal and external
journey. Let's investigate!
I think it's good for scientists to keep questioning theories that were already thought of fact or true. I mean, it's been so many years and just now we come to realize the sign was wrong.
ReplyDeleteI loved your ending paragraph. we should definitely expand our knowledge the same way the universe seems to keep expanding.
I think in many ways our brains are miniature versions of the universe. Sometimes, we need to look inside to understand what is outside.
ReplyDeleteI think that we can be wrong in some of our theories as scientists, just like he said about Einstein. The reality is that the universe, the matter and the nature, are very complex systems, but is a privilage for me (as a scientist) to know more every day about them. I hope I could be there so hear his exceptional speech.
ReplyDeleteOMG LOVE IT
ReplyDeletethat ending was soooo perfect <3
His research is definitely eye-opening. I wish I could have gone!
