I would also say, that we want to understand the laws of physics better,' Riess said.Īnd, if it happens that a new type of physics is discovered, Riess predicts this will inspire more technological advancements and essentially create a snowball effect of innovation. And to those I would just say, we’re curious. Mostly, everything’s up there, but I understand that what those people care about is happening here on planet Earth. 'I tend to find that there’s almost two kinds of people, those who are completely fascinated about the mystery of what’s out there where do we come from what’s the universe made of how did it start, how old is it what’s going to happen where do we fit in all this? And to those people, they understand immediately, ‘Wow, this is really profound.’ And then, I’ll admit, there are people who are like, ‘Wow, why would I ever care, why even look up? Everything’s down here.’ And it’s not true that everything’s down here. While Riess said it isn’t exactly certain what this new physics could be and, because this is just a hypothesis, more research needs to be done and that’s always exciting. Dark matter makes up about 30% of that and dark energy makes up between 65%-70%.

So far, 96% of the universe is made up of dark and unknown parts, according to Riess. Some examples of newer physics that were discovered in recent years include dark matter and dark energy. The current hypothesis as to why the numbers aren’t matching up for how quickly the universe is expanding could be because there is a new kind of physics of which scientists are unaware. In fact, it opens up a whole new avenue of possibilities to further our knowledge of what’s going on in that big expansion of darkness dotted with galaxies. This newest discrepancy isn’t exactly bad news, according to Riess.

In this most recent study, the universe is believed to be expanding at a Hubble constant value of 73 plus or minus 1 kilometer per second per megaparsec.

The most recent measurement is accurate with a 1 1/2% uncertainty, which, according to Riess, is very accurate. And so in our case, the hard part is measuring how far away things are, and we use the Hubble Space Telescope to look at stars very, very far away and if we can recognize what kind of stars they are, then we can know how luminous they ought to be and then comparing that to how faint they actually are tells us how far away they are,' Riess explained. 'We have to measure how tall, which in this case means how far away things are, and the time stamp which is like measuring something else we call the red shift, and it’s basically how far away, how fast things are expanding away from us. Scientists use cosmic mile markers such as distant galaxies and stars to track how far and how fast the universe has expanded. The same would go for measuring how fast the universe expands. When tracking the growth of a child, one might mark a door frame indicating the child’s height, date and time. Scientists measure the expansion of the universe using the Hubble constant (Ho). How is the expansion of the universe measured? So now we have to really put our thinking caps on and understand why is it that you can’t go from the beginning of the universe to the end with a story that connects the two and something breaks down along the way,' Riess added. We’ve done too many measurements and cross-checked them too much to say it’s bad luck. 'So we’re at a point now where it’s not just bad luck that these don’t match each other.

Which is strange but exciting because in science, any time something doesn’t match your model, you have the potential to learn more about your model or your understanding,' Riess told FOX TV Stations. 'The funny thing is, it doesn’t match the prediction. However, Riess’ team showed the universe is actually expanding 73 plus or minus 1 kilometer per second per megaparsec, which predicts the size of the universe will double in about 10 billion years. Previous measurements predicted the universe was expanding at a rate of 67.5 plus or minus 0.5 kilometers per second per megaparsec, according to NASA. When comparing measurements from previous data and the current data, Riess’ team found that the rate at which the universe is expanding was off. 'You are getting the most precise measurement of the expansion rate for the universe from the gold standard of telescopes and cosmic mile markers,' Riess said.
