Neil deGrasse Tyson on the Biggest Misconceptions We Have About the Universe

“If the sun were hollow you could pour a million Earths inside of it.”

National Universal treasure, star of Cosmos: A Spacetime Odyssey, and Frederick P. Rose Director of the Hayden Planetarium, Neil DeGrasse Tyson, has a knack for taking complex scientific ideas and explaining them in understandable and awe-inspiring ways. Recently, he sat down with Tech Insider to discuss how and why humans have a difficult time perceiving the vastness of our universe.

Here are just a few pieces of science NGT drops in the video below:


  • “We don’t have an intuitive sense of how deep time really goes.”
  • “If the sun were hollow you could pour a million Earths inside of it.”
  • “There are more molecules in a cup of water than there are cups of water in the oceans of the world.”

McDonalds sells a lot of coffee. Over a billion cups a year, to be exact. All that coffee leads to a lot of productive mornings, but it also leads to a lot of waste. Each year, millions of pounds of coffee chaff (the skin of the coffee beans that comes off during roasting) ends up getting turned into mulch. Some coffee chaff just gets burned, leading to an increase in CO2.

Now, that chaff is going to get turned into car parts. Ford is incorporating coffee chaff from McDonalds coffee into the headlamps of some cars. Ford has been using plastic and talc to make its headlamps, but this new process will reduce the reliance on talc, a non-renewable mineral. The chaff is heated to high temperatures under low oxygen and mixed with plastic and other additives. The bioplastic can then be formed into shapes.

For over 20 years, our country has perceived itself as more divided than united, and it's not getting better. Right after the 2016 election, a poll conducted by Gallup found that 77% of Americans felt the country was divided on the most important values, a record high.

The percentage of Americans who agree that we disagree got higher. During the 2018 mid-term elections, a poll conducted by NBC News/Wall Street Journal found that 80% of Americans felt the nation was "mainly" or "totally" divided.

We head into the 2020 presidential election more divided than ever. A new poll from USA Today found that nine out of ten respondents felt it was important to do something about the conflict in our country. We can't keep on living like this forever.

The problem with American Sign Language (ASL) is that over 500,000 people in the U.S. use it, but the country has over 330 million people.

So for those with hearing loss, the chances of coming into contact with someone who uses the language are rare. Especially outside of the deaf community.
