7 Life Extension Technologies That Could Help You Live To 150

Billions of dollars are going into age research, and many experts believe that we’re on the cusp of beating aging. Here are 7 technologies and strategies to look out for.

 

Caloric restriction or dietary restriction is a diet that decreases your calorie consumption by at least 30%. People on caloric restriction eat very little food along with a regimen of vitamins to make sure they get all the nutrients they need. They say it lowers your body’s metabolism by putting your body into a fasting state.

The theory is that when your body is in a fasting state, it focuses its energy on tissue repair, which means less tissue damage and a longer lifespan.

Experiments with caloric restriction in mice showed up to a 45% increase in lifespan, and similar results were found in experiments with rhesus monkeys.

But studies have started showing similar results from intermittent fasting.

There are different types of intermittent fasting, one involves fasting every day, basically not eating until late in the afternoon. This is actually advocated by the actor Terry Crewes.

This has some noted benefits but the type of fasting that’s of interest to age research involves going for 5 days a month without eating.

Studies tend to show that this puts your body into extreme tissue repair and is even helps prevent cancer.

One of the things that causes the most metabolic wear and tear on your cells is oxidative stress.

Luckily there are antioxidants that bind to the free radicals and prevents them from damaging the cells. Just in case you ever wondered what the whole antioxidant thing was all about.

Now antioxidant supplementation has shown a lot of promise in preventing different types of cancers, but it hasn’t shown to really affect the aging process.

A lot of research in the last couple decades has focused on telomeres.

Well, scientists discovered that these telomeres get shorter every time your cell and chromosomes divide and the theory is that over time throughout your life, this leads to the chromosomes and the DNA becoming frayed, which leads to cells becoming damaged and thus, stop reproducing.

This is a point known as the Hayflick limit.

But, they discovered an enzyme that’s created in cells that reproduce often like skin cells and more so in stem cells called telomerase that actually lengthens and prevents the shortening of telomeres, meaning the cells and tissues survive much longer before hitting the Hayflick limit.

This was a big deal, and won the Nobel Prize for Physiology and Medicine in 2009.

But the drug that’s really got everyone talking these days is metformin.

Metformin is a drug that’s been used since the 1950s to treat diabetes, so it’s nothing new. But researchers started noticing something over the decades.

Patients who took metformin tended to live longer and suffer from fewer age-related illnesses. One study found that diabetics on metformin not only lived longer than diabetics who aren’t on metformin, they lived longer than non-diabetic people as well.

You really can’t talk about aging research without talking about Aubrey De Grey. He’s the founder and head scientist at the SENS Research Foundation and the SENS foundation has pinpointed 7 different categories of cellular damage that leads to aging and has set about fixing them one by one.

But of course, the ultimate option is nanobots.

Swarms of blood-cell size robots that can be programmed to repair tissues, destroy tumors, clean blockages in our arteries and physically connect neurons are the ultimate life expander.

Elon Musk’s 2017 SpaceX Update For Mars

On Friday, Elon Musk spoke to the International Astronautical Conference in Adelaide Australia to update us on his plans for SpaceX. Here’s the nuts and bolts of it.

Friday, Elon took the stage at the International Astronautical Conference in Adelaide Australia and around the world, musketeers gathered around their computers to watch their favorite billionaire visionary slash chief executive stammerer talk about his new plans for Mars.

But that’s not really what they got.

Yes, Elon talked about Mars, but this wasn’t really about Mars so much as it was about the future of SpaceX.

And the first hint of the future of SpaceX is the name he used for their rocket.

Last year, the spaceship he presented was referred to as the ITS, for Interplanetary Transport System.

This was a rocket system specifically designed for voyages to Mars and beyond. This time, the letters ITS were never used. Instead, he went with BFR. For Big F*cking Rocket.

Musk’s new version of the BFR gets smaller, and far, far more versatile.

Satellite deployment, refueling, lunar landing, and shuttling astronauts to the ISS. And as this picture shows, it’s still a pretty big fucking rocket.

This is the future of SpaceX. A one-size-fits all workhorse that can perform a wide variety of functions with only slight modifications to the original design.

In fact, he said that this configuration would make everything before it obsolete, which makes me wonder what is the future of the Falcon Heavy and the Dragon 2?

This workhorse has 31 engines in the first stage as opposed to 42 in the original design. And it’s designed to carry 4400 tons of vehicle mass with 5400 tons of thrust.

He showed in a chart just how much more that is than any other rocket, including the Falcon Heavy. By a long shot.

So maybe the Heavy will just be kept around for special payloads that require it? I don’t know.

But the second stage had a few major changes, including a small delta wing with yaw and pitch controls for better control during re-entry.

He described the crewship as a combination of the Falcon 9 second stage and the Dragon capsule, but bigger.

The crew cabin is designed to carry up to 100 passengers with 40 capsules that Elon says are built for 2 to 3 people each, though you could get 5 in there if you weren’t claustrophobic.

And he says it has as much cabin space as an Airbus 380, which just for reference can carry 853 passengers fully loaded.

One thing that was new was he talked about lunar expeditions and possibly setting up a moon base, which is new for SpaceX but also in line with NASA’s plan to return to the moon.

This obviously positions SpaceX to get some government contracts for lunar missions, which could be a money maker for the BFR.

And back to Mars, he showed a visualization of how the Mars landing would work, using that delta wing shape to slow the craft down in the atmosphere before doing a propulsive landing.

Now he did say that the Mars missions would require producing fuel on Mars, which in rocketspeak is In-Situ Resource Utilization.

Elon’s new timeline put the first trips to Mars in 2022, these are unmanned missions that will carry solar-powered fuel plants to carry out all the stuff I just talked about, along with cargo and food for future missions.

In 2024, he wants to launch 4 ships to Mars, 2 crewed and 2 uncrewed, which are stocked with provisions for a long stay on Mars.

And he showed how a base would start with one landing pad, then becoming multiple landing pads, and growing out a city from there.

Elon himself called these timelines “aspirational” but did say they are already starting to build the first ship so maybe we’ll see these things sooner than we think.

But the big surprise of the night came at the end when Elon channeled his inner Steve Jobs and had one more thing. And suggested that if these rockets could send people to Mars, why not other places on Earth? And unveiled this plan.

It would ferry people to a floating launch pad and launch them to the other side of the world at 27,000 miles per hour, where it would propulsively land less than 30 minutes later.
Basically make long-distance trips as much of a time cost as commuting in bad traffic.

==================

From the concepts of George Lemaitre and Edwin Hubble, the Big Bang Theory developed to explain the expansion of our universe, the development of the four fundamental forces and the standard model of particle physics.

Another theory, called Ekpyrotic Theory, attempts to explain the holes in the Big Bang Theory by merging general relativity with string theory.

TRANSCRIPT:

SETI, or the Search for Extraterrestrial Intelligence, has access to telescopes all around the world, constantly scanning the sky for signals of alien communication.

Processing all of this information is a gargantuan task that would require a massive supercomputer that SETI can’t quite afford. So they came up with a brilliant idea.

It’s called SETI at home. It’s a program you can install on your computer that processes tiny parts of that data in the background.

Spreading that data across thousands of computers around the world, they’re able to crank through mountains of information, without the mountainous cost of a supercomputer.

But back in the 70’s none of that existed. Signals from space had to be printed out and processed by hand.

Which is exactly what astronomer Jerry Ehman was doing on August 18th, 1977. He was going over reams of printouts when he found a massive spike in a certain frequency of radio wave.

It was a spike 30 times higher than the background noise, and it was so noteworthy, he literally wrote “Wow” on the page.

It has since become known as the wow signal, and it’s still confusing scientists 40 years later.

The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971.

Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky.

When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from.

In 1956 on the grounds of Ohio Wesleyan University, construction crews broke ground on a massive telescope the size of three football fields to monitor the sky for radio signals from deep space.

It was officially known as the Ohio State University Radio Observatory, because it was actually run by Ohio State, but it was more well known by its nickname. The Big Ear.

The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971.

Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky.

When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from.

So a popular misconception with the wow signal is that 6EQUJ5 is some kind of alien code that we received but it’s actually just a measure of signal strength.

Ehrman and others immediately started pointing telescopes at the spot where the signal originated, which is in the constellation Sagittarius, but nothing has ever shown up.

So, it’s not a star or galaxy or pulsar or black hole because we’d pick up more signals from that location. As far as we know, and we’ve looked there a lot at this point, there’s nothing there.

At least, no cosmic body that would normally produce a radio stream like that.

But the mystery actually gets deeper. Because the frequency that this signal was found on was 1420 MHz. And if you were paying attention in last week’s video about the Voyager missions, 1420 mHz is the frequency that hydrogen atoms expel photons during hyperfine transitions.

(also known as 21-centimeter line or hydrogen line)

This same frequency was used by Carl Sagan and Frank Drake when creating the Pioneer and Voyager plaques as a way to communicate with an alien species should they ever come across the spacecraft.

A Matryoshka Brain is considered a Type 2 stellar engine, a machine that is powered by a star. The idea of a Matrioshka Brain is to stack multiple Dyson Spheres inside each other to collect all the energy coming out of a star and connect those spheres into a massive computer. It’s thought that civilizations that create a Matryoshka brain would upload their consciousnesses into the computer and live in the computer as a simulation.

Partial Transcript:

For hundreds, even thousands of years, the horse was humanity’s go-to form of transportation. And in 13 years, that all changed.

Right now, we are on the cusp of a technological disruption that will make the switch from horses to cars look like switching from Coke to Pepsi.

So we talk a lot on this channel about exponential growth, artificial intelligence, the singularity, and that’s a lot of fun, but there is a dark side to all this change, one that really needs to be talked about because the way we respond to it is going to significantly alter our future as a species.

The BBC released a report just a few weeks ago that said that 30% of jobs are going to go away in the next 10 years because of automation.

In the U.S., we’ve heard a lot over the last election about the proverbial coal miners and our current president specifically campaigning to bring back coal jobs.

But coal is just one of hundreds of industries that are taking advantage of employees that can work 24/7, never need a bathroom break, never sleep, never make a mistake and work twice as fast. Oh, and you don’t have to pay them.

Factories already decimated by outsourcing are now losing even more jobs to automation. And as automation becomes more sophisticated, more industries are at risk.

The transportation sector actually makes up 25% of the jobs in the United States, if you can believe that. A full quarter of the population. And autonomous cars… They’re pretty much here, guys.

Famously, the Tesla Model 3, going into production this year, will have autonomous capability, though it may not have the software available, it will have the hardware ready for it.

But less famously, there are a lot of other car companies trying to beat Tesla to market with this. Nissan has a fully self-driving prototype in development that they took a drive in on Fully Charged and it was spooky how good it was.

Cadillac is so bullish on self-driving technology, they spent millions of dollars to create a lidar map of every highway in the United States using their own proprietary system.

This way their cars won’t just rely on sensors and GPS to find their way, the Cadillac system will contain a 3D map of everything, including the roadsigns.

Google’s working on a car, Apple supposedly is working on a car, but the people who are really big on this technology are the service providers.

Uber made over 2 billion dollars last year. Imagine how much they could make if they didn’t have to pay their drivers…

Uber has been working for years on a transportation fleet of autonomous cars, and even Ford has made some intentions known of pivoting in a similar direction.

Many are predicting that cars will go from a retail industry to a service industry, with Peter Diamandis saying that in ten years, car ownership will be an outdated idea.

The fact of the matter is, you can be for automation or against it, you can agree with its use or not, but this is happening. And we need to be ready for it.

Some people are talking about a basic minimum income, a flat amount of money that everybody in a society makes, as a safety net to keep people above water. This is an interesting idea that’s even being tested in some places.

There is a coming change on a fundamental and massive level in this world. One that is filled with amazing advancements and technological wonders. The question is, will we be able to change with it?

Why Is The Speed Of Light The Speed Of Light?


You may be familiar with the speed of light, but the reason it exists and how we discovered it is pretty fascinating.

Transcript:

So when we talk about the speed of light, the first thing to remember is that light is just a sliver of the entire electromagnetic spectrum, ranging from gamma rays to radio waves.

So we’re really talking about the speed of electromagnetism.

James Clerk Maxwell was the genius who first described the properties of electromagnetism into physics equations.

From these equations, we can calculate the speed of light 299,792 kilometers per second.

Einstein was able to prove his theory of special relativity that the closer you get to the speed of light, the more time slows down for a person in that relative frame.

And if you were to go the speed of light, time would stop altogether.

So if you were able to travel faster than light through spacetime, time itself would actually flip. Time would go backward. And that would break causality.

The effect would precede cause, which is impossible. The speed of light is the speed of causality.

The other prediction that supports a speed limit is the idea that inertia increases as velocity approaches the speed of light.That means mass increases.

So mass is a speed impediment. Nothing that has mass can go the speed of light.

But if you are massless, you can only go the speed of light, because you have no speed impediments. And photons are massless particles.

Particles that must travel at the speed of light and because they are traveling at the speed of light, time stands still from its point of view.

So really, that video I talked about earlier is all wrong, from the perspective of the photon, that journey would have occurred instantly.

So when you look at a star at night, that massless photon might have traveled a million light-years to reach you, but its experience was instantaneous.

Now there is another theory that’s a little controversial but starting to gain some ground.

It says that the speed of light is actually caused by quantum vacuum fluctuations.

See, quantum field theory claims that empty space is actually not empty at all but filled with quantum fluctuations and virtual particles popping in and out of existence.

And two different teams of researchers have calculated c using electromagnetic properties of the quantum vacuum, so it could be that the quantum foam of virtual particles and fluctuations may be slowing the speed of light.

But what if the speed of light wasn’t the speed of light?

What if Galileo was right and the speed is infinite?

Then nothing would exist. Because matter is made of energy, it would take infinite energy to create any mass. Time and space wouldn’t exist because all things communicate with each other instantaneously. Cause and effect wouldn’t exist.

But if the speed of light were slower, that might be even cooler. Because then we could see all the way back to the big bang.

The speed of light, of course, is just one of many constants in the universe, like gravity, the specific charges and masses of the fundamental particles, quantum effects, and the list goes on.

A whole handful of very specific constants that if they were just a little bit different, we would never exist.
