The Andromeda galaxy and everything else in the known universe, including us, could be part of an advanced simulation. Indeed, this is the most probable scenario, SpaceX CEO Elon Musk said on comedian Joe Rogan’s podcast on Sept. 7, 2018.

Elon Musk thinks we’re all probably trapped in a “Matrix”-like pseudo existence.

The universe is 13.8 billion years old, so any civilizations that may have arisen throughout the cosmos have had loads and loads of time to hone their technological know-how, the SpaceX founder and CEO explained early this morning (Sept. 7) during a long, wide-ranging and very entertaining appearance on comedian Joe Rogan’s popular podcast, “The Joe Rogan Experience.”

“If you assume any rate of improvement at all, then games will be indistinguishable from reality, or civilization will end. One of those two things will occur,” Musk said. “Therefore, we are most likely in a simulation, because we exist.” [13 Ways to Hunt Intelligent Aliens]

“I think most likely — this is just about probability — there are many, many simulations,” he added. “You might as well call them reality, or you could call them multiverse.”

The “substrate” on which these simulations are running, whatever it may be, is probably quite boring, at least compared to the simulations themselves, Musk further told Rogan.

“Why would you make a simulation that’s boring? You’d make a simulation that’s way more interesting than base reality,” Musk said, citing the video games and movies that humanity makes, which are “distillation[s] of what’s interesting about life.”

The billionaire entrepreneur is far from alone in this interpretation; a number of physicists, cosmologists and philosophers find the simulation hypothesis compelling. If even one advanced alien civilization with a predilection for creating simulations has ever arisen out there, the reasoning goes, then it could theoretically pop off thousands — or perhaps even millions or billions — of “fake” universes. And it would be hard for the inhabitants of these digital realms to figure out the truth, because all the evidence they could gather would likely be planted by the creators. 

Indeed, the simulation idea is one of many possible explanations for the famous Fermi paradox, which basically asks, “Where is everybody?” (“Everybody” being aliens, of course.)

SpaceX's 1st 'Block 5' Rocket: A Tale of 2 Launches

CAPE CANAVERAL, Fla. — Back in May, I stood near a massive blue countdown clock as the minutes and seconds ticked away to zero. I was surrounded by fellow space reporters, a small group of whom traveled to Florida all the way from Bangladesh. The excitement built and built — and then the launch scrubbed. The Falcon 9 just wasn’t ready to fly that day. But the next day would be a different story. 

We all returned to our same viewing spot, adjacent to the countdown clock, and stared across the water at the sleek black-and-white Falcon 9 perched atop its launchpad, Pad 39A at Kennedy Space Center. This time, everything proceeded as expected: When the clock hit zero, smoke billowed and bright flames lit up the sky as the Falcon roared to life. The sound waves that washed over us several seconds later were noticeably louder than expected, even for this experienced launch-watcher. That’s because this wasn’t an ordinary Falcon, but a souped-up version. 

Known as the Block 5, this is the final variant of SpaceX’s workhorse — meaning there will be no more major design changes. The design will stay the same from now on to help SpaceX achieve a major goal: rapid reusability. [See all our photos from the Block 5’s two launches]

The company already reuses the first stages of its spacecraft, but this iteration will take that to the next level. Previous versions of the Falcon 9 could be used only two or three times, which is an incredible accomplishment, but not enough for SpaceX founder Elon Musk. His plan is to make rockets more like commercial airplanes, capable of flying many times with no action (other than refueling) taken in between flights. According to Musk, the Block 5, which is a culmination of more than 10 years of development, will do just that.

To work toward that goal, SpaceX engineers outfitted this turbocharged Falcon with some sweet upgrades over its predecessors. The design changes — which include improved engines, a more durable interstage (the piece that connects the rocket’s two stages), titanium grid fins and a new thermal protection system — will help the booster hold up better to launch stresses. According to SpaceX, each Block 5 can fly 10 times or more times before requiring light refurbishments, and as many as 100 times before the booster is retired.

Musk has said that we will see a Block 5 launch, land and relaunch within the same day sometime next year. As the months tick away and the aerospace company focuses on its big task for the year, launching the first uncrewed test flight of the commercial crew program, that goal remains a lofty one. However, a more reasonable goal — one that SpaceX is close to achieving — is to see the same Block 5 booster launch more than two times in a year. 

Although it hasn’t reached that goal yet, I watched it get closer when I saw the same booster launch again. [Photos: SpaceX Launches, Lands 1st ‘Block 5’ Falcon 9 Rocket]

Following the first Block 5 launch on May 11, which placed Bangladesh’s first satellite — the Bangabandhu-1 — in orbit, SpaceX officials said they didn’t know when the recovered booster would fly again, as they would most likely take it apart and inspect it to make sure it performed as expected. So, it was a bit of a surprise when the company announced that the Bangabhandu-1 booster would fly again on Aug. 7, just 12 weeks later. 

That second launch, at Cape Canaveral’s Pad 40, may have been more of a spectacle than the first. It’s like with each launch the booster tries to outshine itself. Sitting in folding chairs on a causeway across the water from the launchpad, a group of space reporters waited. The Milky Way was barely visible overhead. One spectator even brought a telescope, and we peeked at Mars — which shined above like a glowing copper orb — before turning the scope to the launchpad. 

The Falcon appeared upside down in the viewfinder but stood ready to launch. We could see what looked like breath emanating from the rocket as the last of the cryogenic fuels that power the rocket were loaded. As the clock hit zero, the night sky lit up bright orange as the Falcon roared to life. Its engines were just as unexpectedly loud as they were the first time. But unlike its first trip to space, which was a bit more dramatic with several holds and a scrub, this flight went off right at the beginning of the window.

As the Falcon climbed to space, the glow from its engines could be seen for several minutes. Surprisingly, after the booster separated from the upper stage and started its descent, far in the distance, we could see the Falcon’s engines ignite for the first of its multiple planned landing burns. Cheers erupted over the loudspeaker as confirmation came in that the booster had touched down on the drone ship a second time.

SpaceX’s successful launch and landing of the Block 5 booster (on the company’s East Coast-based drone ship “Of Course I Still Love You“) with so little time in between is a huge step toward quicker re-flight times.

In another surprising twist, and before the second landing was confirmed a success, the SpaceX launch webcast seemed to suggest that this booster would fly a third time before the end of the year. (Good thing it stuck its landing). Though which mission that booster will be used on hasn’t been announced yet.

A few days after its second flight, the booster stood proudly perched on the deck of the drone ship as it made its way back to port. I stood with a crowd of rocket enthusiasts on the docks, welcoming B1046 (a designation given by SpaceX to identify the booster), some of the space buffs tracking the ship it rode in on to ensure they would get the first glimpse as it peeked over the horizon.

Elon Musk, Tesla, stock, private, buyout

He stunned investors on Tuesday with a tweet saying he had already lined up the funding, and he told employees that it would relieve the electric car company of the “enormous pressure” of Wall Street’s expectations.

In a letter to Tesla workers that was posted on the company’s blog, Musk called his idea the “best path forward.”

“As a public company, we are subject to wild swings in our stock price that can be a major distraction for everyone working at Tesla, all of whom are shareholders,” he wrote.

He also said trading its stock publicly “means that there are large numbers of people who have the incentive to attack the company.” Musk has complained repeatedly about short-sellers, who profit when Tesla stock drops.

Musk, the CEO and largest shareholder, said on Twitter that the private funding valued Tesla at $420 per share. Tesla is already the most valuable automaker in the United States.

Musk’s tweet caused shares to spike

The plan would need shareholder approval, but Musk’s tweet sent Tesla stock spiking by almost 9%. Trading in Tesla was later halted for more than an hour before Tesla posted Musk’s letter to employees on its blog. It finished up 11%, at $379.

The stock had climbed slightly earlier in the day after the Financial Times reported that Saudi Arabia has quietly built a big stake in the company.

At first, Tesla had declined comment on Musk’s tweet, even as he casually engaged Twitter followers with more posts about his plans.

Musk said that he hoped all current investors would stay with Tesla even if it went private. He said he would create a special fund to allow that. Fidelity, the investment firm, has such a fund for its stake in SpaceX, a separate private company also run by Musk.

He pledged to hold on to his stake in the company, about 20%, no matter what. He said he was “super appreciative” of Tesla shareholders, and vowed to “ensure their prosperity in any scenario.”
