Time Is Not the Same for Everyone #Interstellar (Spoiler Free)

The movie Interstellar involves many interesting scientific concepts, including the fluidity of time. On Earth, time moves at the same speed for all of us – otherwise our watches would constantly need to change how fast they move.  However, time can change in two specific scenarios.

If someone is moving significantly faster than us on Earth

If someone is under the effects of more gravity than us on Earth

Astronauts on the International Space Station (ISS) experience this.  As they orbit the Earth, the gravitational pull keeps them in orbit, and makes them move much faster than we are on Earth.  As a result, they age less than us.

If the same astronauts wanted to head away from Earth at an extremely fast speed – near the speed of light – they would age slower than us during the trip.  If the destination was an object with more significantly more gravity than the Earth – like a black hole – they would continue to age slower while under the effects of increased gravity.

That’s the genius of media – you can enjoy the adventure and emotion presented in the movie, and OPTIONALLY it can spark a light of curiosity that leads one to further research.

Shouldn't that be what science education is about?

R.I.P. Michael Alsbury #SpaceShipTwo

(Note: Please donate to the Mike Alsbury Memorial Fund, as he leaves behind a wife and two small children ages 10 and 17.)

It's been a rough week for space travel. First, an unmanned ISS resupply rocket launched erratically and had to be destroyed by NASA safety operators. Next, the Virgin Galactic spacecraft SpaceShipTwo suffered a mishap that resulted in the loss of life. Pilot Michael Alsbury was killed when SpaceShipTwo crashed in the Mojave Desert while attempting to land.

Heroes like Alsbury put their lives on the line to push forward space research. It's critical that we not take this loss for granted, and they we can continue to push forward to support what Alsbury lived for - taking space exploration to the next level.

The Guardian has a nice writeup of Alsbury's accomplishments. From that article:

Alsbury earned a degree in aeronautical engineering from California Polytechnic State University, San Luis Obispo. He was the recipient of Northrop Grumman’s President’s Award for Innovation-for-Affordability Excellence this year.

Alsbury was a “home-schooled, home-brewed” pilot who earned his way up through the ranks at the company, starting as an engineer. Alsbury had also put himself through commercial pilot school and was certified as a flight instructor.

Scaled Composite, Alsbury's company of 15 years, released a short statement in his honor

Chat with Creators of Sci-Fi Show Extant

The CBS sci-fi show Extant, which recently wrapped up its first season.  It inspired a few posts of mine about the constellation Orion, the speed of sound versus the speed of light, and the idea of being weightless. On a personal level, I enjoyed seeing a prime time sci-fi television show with a Black woman as the lead.

I was lucky enough to be invited on the Black Girl Nerds podcast to speak with Extant creator Mickey Fisher and show runner Greg Walker.  We chatted about the show, diversity in sci fi, bloopers on the set, and other shenanigans. Check it out below!

Ebola Isn't Just Fear Mongering

There have been many accusations that the current Ebola outbreak is another example of fear mongering, or deliberately focusing on the fear involved with an issue. This could not be further from the truth.  It's important to understand that Ebola is a very serious fever that is often fatal in humans. The World Heath Organizations (WHO) defines the current Ebola outbreak as "the largest and most complex Ebola outbreak since the Ebola virus was first discovered in 1976." 

There has been a lot of false information flying around the news, mostly from people that are not versed in science. Check out two scientific sources below for some great facts on this disease:

From Dr. Calelph Wilson's story in Ebony:

"Evidenced-based information is critical.  Social media such as Twitter is a rapid way to access expert information and conversations on Ebola. For example, the National Science & Technology News Service (NSTNS, of which I am a member) recently hosted an Ebola Twitter chat with Professor A.O. Fuller, a virus expert from the University of Michigan. There are a host of Ebola virus related hashtags with very good information. It is critical to avoid sources that claim that Ebola is a hoax, a conspiracy or isn’t real without any basis."

From Dr. Marshall Shepherd's story in the Washington Post:

"I suspect that federal agencies like NIH and CDC have also suffered from gamesmanship. I can’t imagine that they have not been diligently thinking about the Ebola problem for years. However, I can imagine that budget cuts and other stresses on the science infrastructure and funding agencies would affect capability. "

#Ferguson & Chemical War Agents: Wrong

There have been protests for the last few days in Ferguson, MO, due to the unjustified shooting of Michael Brown, an unarmed Black man. I hate to say "another" but it's true -this Mother Jones article focuses on four unarmed Black men shot in the last month!  Michael Brown, Eric Garner, John Crawford, and Ezell Ford join an ever growing list with such names as Rekia Boyd, Tarika Wilson, Sean Bell and Amadou Diallo.

This is an American tragedy, and it pains me to see so many lives wasted. Protests are well justified, and police have heightened the tension by excessively deploying military grade tanks and guns acquired through the controversial 1033 program.  In addition, police are using tear gas (also known as CS gas), which is more dangerous than you may think. According to Discovery Magazine:

"Despite it’s “non-toxic” reputation, CS is prohibited for use in warfare by the Chemical Weapons Convention that was signed by many countries (including the US) in 1993. It is classified as a chemical warfare agent. However, this does not apply to domestic use of it or any tear gas, and police use of CS is legal in many countries, including the United States."

Why would it be listed as a chemical war agent? Here's a list of common CS gas effects, all of which have been mentioned on the #Ferguson twitter hashtag:

  • stinging and burning of the eyes, nose, mouth, and skin
  • excessive tearing
  • blurred vision
  • runny nose
  • salivation (drooling)
  • exposed tissue may develop a rash and a chemical burn
  • coughing and difficulty breathing, including a feeling of choking
  • disorientation and confusion, which may lead to panic

These are the effects of a chemical war agent used against unarmed peaceful protesters in an American city. Also note that these effects are much more intense and possibly deadly for someone with existing respiratory problems.

In a 2013 interview with National Geographic, Sven-Eric Jordt, a professor of pharmacology at Yale University School of Medicine who discovered the connection between tear gas and pain receptors, shared his view on the use of tear gas.

"Law enforcement has to weigh the risk of tear gas injury of bystanders against gaining control in a riot situation, under the assumption that rioters break the law. Governments need to put in place immediate decontamination procedures for areas, and especially residences, when tear gas is used."

Jordt emphasized that such a dangerous war asset should be used to gain control in a riot situation.  All of the footage from Ferguson indicates groups of protesters standing firm and vocalizing their frustration, even despite a few bad apple that choose to loot.  There is no sense of a loss of control. A response with tear gas is just inhumane.

So far, there has been no reporting on any decontamination procedures used by the Ferguson police department, or any assistance to the medical personnel that will be burdened with people seeking treatment.

This needs to stop. I stand in solidarity with Ferguson.
