Tonight, an emotional victory for more than 100 young women who joined forces against the man they say sexually abused them back when many of them were just little girls. The chairs in the courtroom signaling another bold step forward for women in this historic me too moment as the judge effectively condemned him to a life sentence. Heres abcs Lindsey Davis. Reporter the man accused of sexually abusing girls, one as young as 6 years old finally founds out his fate today. You do not deserve to walk outside of a prison ever again. Reporter crimes so traumatizing that when the former doctor for usa gymnastics was escorted out, the courtroom erupted in cheers. When you heard the judge announce 175 years, what was your reaction . I was so happy. Because i know that hes never going to be going back out into the public and hes not going to be able to harm another girl again. Reporter 17yearold Stephanie Robinson said she also suffered sexual abuse at the hands of nassar. Learning how to deal with it and being able to talk about it. At first i was really afraid to speak about it or even let anyone know this happened to me and i was a victim of this. But now i know im a survivor. Reporter she testified last wednesday. Her father by her side. Im disgusted by your actions. May you never hurt or abuse another person again. Reporter stephanie was one of 156 women and girls who testified at nassars sentencing hearing. Youre pure evil. Reporter over the course of the last seven days. Without my knowledge or consent, i had engaged in my first sexual experience by kindergarten. You hid for years behind Olympic Rings and a spartan head but theres nowhere left for you to hide, larry. I cant even put into words how much i [ bleep ] hate you. Reporter more than 150 women have accused nassar of sexual abuse. Among them, some of the biggest names in usa gymnastics including Gabby Douglas and aly raisman. Treatments with you were mandatory. Lying on my stomach with you on my bed insisting that your inappropriate touch would help to heal my pain. Some of the greatest athletes on earth and theyre fearless and they deliver. One of the most important time of their lives and yet theyre so vulnerable. Reporter many of these young womens testimony so heart breaking and difficult to hear, even nassar broke down as some of his victims spoke. Wow. What have you done . She shook, took off his glazs and at times wiped away tears. Today, it was nassars turn to speak, making one last appeal for leniency. No words for this past several days. No words. They have had an emotional effect on myself and shaken me to my core. I also recognize that what im failing pales in comparison to the pain, trauma and emotional destruction that all of you are feeling. Reporter but the judge wasnt buying it. So highlight his insincerity, she read outloud, nassar ear earlier words in a letter to the court. In the letter, he claimed the victims were after Media Attention and money. Hell hath no fury likeury lie woman scorned. The judge asked. Reporter the judge asked if he wanted to drit withdraw his guilty plea. But he wouldnt even say the word. Do you want to take back your guilty plea . I said my plea. Reporter last november, nassar pleaded guilty to seven counts of first degree criminal Sexual Assault. His accusers say he would use his hand to penetrate them, claiming it was part of treatment. For all those involved for that insult, im horribly sorry. This was like a forest fire out of control. And i pray to the rosary every day for forgiveness. I want them to heal. Reporter the father of three was arrested in 2016 after this woman went public with what she said nassar did to her. This was just after my 15th birthday. I saw him for approximately a year and he abused me between 10 and 13 times during that time frame. He penetrated me vaginally and anally. Reporter she filed a complaint and told her story to the indianapolis star. Within hours, we had women calling the tip line. By the end of the day, we had 12 other survivors and its grown from there. Over 160 now. Reporter she was the last to testify today. You have fashioned for yourself a prison that is far, far worse than any i could ever put you in. And i pity you for that. Reporter but for many, nassars sentencing is not the end. This is bigger than him. This is way bigger than him. This is about the institutions that protected him and to reiterate, all the statements that have been said before me, everyone in the world should be outraged right now. Reporter in claim that usa gymnastics and Michigan State university turned a blind eye to nassars abuse. Who else at msu had received reports of larrys behavior and did not act . Who else helped contribute to the greatest Sexual Assault scandal in history . Reporter three members of the usa gymnastics board have already resigned, including the chairman paul parilla. Reporter he had more than one accomplice. He was not only enabled by msu and usag, but they actually fed him in his crick tims. Reporter in recent days, team usa has pledged to protect athletes saying usa gymnastics will keep their words and experiences at the core of everything we do as with we remained focused on our highest priority the safety, health and well being of our athletes and creating a culture that empowers and supports them. And last week, the Michigan StateUniversity President attended nassars hearings to offer her support in person. I think there are steps being made towards accountability and other steps that will follow. Reporter but tonight, amidst fallout, simon submitted her letter of resignation. Hearing what these young women had to say and the horrors of it over and over again, the president of Michigan State could not survive that. And she should not have survived that. Reporter and both the ncaa and u. S. Olympic committee have announced independent investigations to determine just who knew what and when. Larry can be sentenced, but if these people are still allowed to be out in society and continue to do the same thing that they did to us, that neets going to fix anything. Reporter when we hear the back story and the horrors behind the scene in the shadows, you cant help but think that usa gymnastics put medals above these girls lives. Reporter tonight, the socalled army of survivors is vowing to continue to fight for women everywhere. Im excited to have a little girl one day hopefully and be able to raise her to know that she is powerful and she is strong and she does have a voice. Because, you know, we have all been able to show our strength this week. Reporter for nightline im Lindsey Davis in lansing, michigan. Our thanks to lindsey.

Tonight we take you to the flat Earth International conference where people believe the globe weve been shown our entire lives is a lie. So do they have proof . Heres abs eva pilgrim. Lets ask basic questions. The sky is . In a world where nothing is as it seems. The sky is blue. 1 plus 1 is . 2. Reporter there is at least one truth we thought was indisputable. And the earth is . Flat. Flat. The earth is flat. My reality, my senses tell me that the earth is flat and stationary. Reporter or so i thought. For the people attending the first flat Earth International conference here in carey, north carolina, their earth indisputably is not round. Everybody here can agree on absolutely one thing, which is it is not a globe. Reporter for century, a flat earth was accepted as certainty until science and sailboats said otherwise. You never admit that theres one bigger than yourself. Reporter but it wasnt until 2015 when this guy posted his flat earth clues. Part of a series of clues that help you get around both the design of the flat earth system we live in. Youre kind of like the father of this movement. Dont do that. Reporter you started it all. I did not invent flat earth. All i did was walk up to a door, point at it and say you know what, i think theres some really interesting things on the other side of this. And check it out for yourself. If flat earth is a university, then i would be the freshman recruiter. Reporter people have traveled around actually, mark would say across the flat world to ascend. The first rule of flat club is you dont talk about flat club. Reporter until now. I have a poem about that. Reporter Amy Nicholson wrote a book about her flat earth journey. I havent really come out all the way yet. Im still a little in the closet. This man came from even farther. I mix with quite a lot of flat earthers in new zealand. You know flat earthers, i guarantee it. But you dont know who they are because theyre afraid of talking about it. One, two, three were not crazy reporter like many modern movements this one has grown in large part out of the internet, with rappers ivan jellizing to hundreds of thousands of subscribers. No more living on a cartoon ball. Reporter and Youtube Channels like globe busters reporter encouraging skepticism about what youve been taught. For the serious students here at the conference and this is got to a point now where its becoming real. When it comes to science, you can test. Fire burns, water is wet, fire burns. Reporter the curving horizon, the sloping sea level, the spin of the earth, unless you can see these phenomena with your own eyes, they may not be true. A lot of people are going this is crazy, right . But think about this. For the last 20, 25 generations, this is what we told people. Reporter unlike what weve been told in school, some flat earthers imagine the earth looks like a snow globe, round but not a sphere. The north pole is at the center of most flat earth maps with the ice of antarctica Holding Everything in. Are you sure that is what the earth looks like . Pretty sure. Almost. The basic concept is sound. Absolutely sound. And one thing again, we absolutely know for a fact this aint it. Reporter those iconic blue marble images we see from space, they denounce them as fake. Composite, animation, something that tells you this is not an actual photograph of the earth. Reporter so if you think you have questions, the flat earthers have many, many more. Which is why i thought someone who has actually seen the earth from space might have some answers. 1 plus 1 i 2. Jimmy wh reporter what color is the sky . Blue. Reporter and the earth is . Round. Reporter this professor spent more than 20 days in space and worked on the hubble telesco telescope. Reporter when you looked at the planet, what did it look like . It looks round, folks. It is round. My eyewitness account. And i looked at it as much as i could. It is round. Were in the final countdown. How you doing over there . Reporter hes played himself on the Big Bang Theory but some flat earthers actually believe astronauts are just actors, part of a huge conspiracy going back to those very first steps on the moon. Thats one small step for man, one giant leap for mankind. You dont believe theyve gone to space . No. The rockets go up, sure. Theres nobody in them. Reporter rob skiva is another up with of the celebrity contrarians in the flat earth movement. His popular youtube videos and podcasts take clues from the bibles book of genesis. Reporter theres no way you can get a spinning globe in the bible. I have become skeptically of everything. Rightfully so. Pretty much everything here is a conspiracy theorist. Thats a common trait. But theres little bit conspiracy theorist in all of us. Reporter its why many of them do their own experiments. Theres going to be some sciency people who say that is a real bogo experiment. They have. Reporter thats a little basic. I know. Its so simple it will go right over your head. Reporter the credo for many of these believers is check it out for yourself. Go out and test. Reporter you just want them to ask the questions. Why do you believe what you believe . And go from there . I could tell you something and you just look at me and say im crazy. Reporter a lot of people watching this will say that man is crazy. Im sure they probably do. I would say well, theyre crazy for not testing what they think they believe. Reporter but in a world of disagreements, large and small, for something as clear as this horizon, the interpretation could be infinite. For nightline im eva pilgrim in carey, north carolina.
