In the ongoing search for extraterrestrial intelligence, it’s easy to become discouraged sometimes, what with all the evidence stacking up for why we’ve never heard from aliens in all the vastness of the cosmos.
Now an astrophysicist from Germany has come up with another sound reason for our frustrating lack of close encounters, and it makes an awful lot of sense when you think about it.
Michael Hippke, an independent researcher affiliated with the Sonneberg Observatory in Germany, says one of the challenges for alien civilisations seeking to explore space would be generating sufficient thrust to escape the gravitational forces of their home planets.
But wait a second, humans developed the ability to launch spacecraft into and across our Solar System last century, so why couldn’t advanced extraterrestrial lifeforms pull off the same trick?
The problem, according to Hippke, are the planets these (hypothetical) beings may (hypothetically) be calling home.
One planet type astronomers and astrophysicists think could offer good prospects for habitability is a Super-Earth – these are rocky exoplanets with significantly higher mass than Earth’s, which could give them thicker atmospheres capable of fostering and shielding alien life on or within their surfaces.
There’s just one drawback with this Super-Earth scenario, but it’s a biggie.
“On more-massive planets, spaceflight would be exponentially more expensive,” Hippke told Space.com.
In his new research, Hippke calculated the amount of thrust alien spacecraft would need to escape the gravitational pull of Super-Earths and even larger, higher-mass worlds.
If conventional rocket fuel were being used, the calculations show it doesn’t take long for the resource to go beyond ‘expensive’ and border on the impossible.
For a launch like the classical Apollo moon mission, a rocket lifting off from a Super-Earth would need approximately 400,000 metric tonnes of fuel in order to take off, which as Hippke writes in his paper, is about the “mass of the Pyramid of Cheops, and is probably a realistic limit for chemical rockets regarding cost constraints”.
Because of this constraint, Hippke calculates chemical rocket launches using conventional fuel would be possible but impractical on Super-Earths, but if the alien world were to get even bigger and have a higher mass, you’d need to start looking at alternative rocket propulsion systems, like nuclear propulsion.
That’s because as the worlds get larger and their mass becomes greater, it gets to the point where chemical fuel would be almost ridiculously underpowered, where “a sizeable fraction of the planet” in fuel amounts would need to be used for every launch, significantly limiting the number of flights possible on alien worlds.
Of course, this being extraterrestrials we’re talking about, it’s entirely possible they may be able to come up with a vastly different alien technology to help get them off-world.
But up until they do that and fly into our field of vision, at least we’ve got another reasonable explanation for why we haven’t met any aliens yet – much as we long to see the day when we do.

A Taos Close Encounter of the Hunters and Aliens Kind
© Jesse Moya/Taos News
Bow hunters Josh Brinkley and Daniel Lucero, dressed in camouflage gear, looked a little uncomfortable sitting in chairs at a local newspaper.
The Santa Fe County residents had just come into Taos after several days in rugged terrain near Cerro de la Olla, also called Pot Mountain, northwest of town near Ute Mountain.
They had a strange tale to tell and they weren’t sure of their reception.
“We’re a couple of guys that don’t believe in much, but we believe now,” Brinkley said.
They went hunting for elk.
They encountered aliens or something else so strange they don’t know what to call it.
Brinkley, 41, said he’s been going to the Pot Mountain area hunting for 15 years. He had never seen anything particularly odd.
He said he works construction and on movie sets. He’s a family guy who doesn’t want anyone to think he’s crazy.
He and Lucero have worked together for eight years.
They say they aren’t prone to seeing things and didn’t particularly believe in aliens.
Opening morning of bow hunting season was Sunday (Sept. 1). The two men had gone a couple of days early to scout the area for elk. Lucero, 26, had never been there.
They set up along the tree line on different sides of a field and waited. After three hours and no elk, Brinkley became restless. It was about 9:30 a.m.
“I take off walking, creeping around through the woods, looking for elk,” Brinkley said.
He reached the top of the mountain where there’s a caldera, a kind of wide bowl left behind by a collapsed volcano. He went to the edge on the southwest side. As he walked to the edge he noticed two figures on his side of the caldera. He thought at first they were hunters. But, they were “very tall shapes of these beings, standing side by side, staring right at me,” he said.
He walked toward them across the brushy field. He estimates they were about 35 yards away. As a bow hunter, where measuring distance is critical to hitting a target, he said he’s pretty adept at it. He went around the bush and looked again. The figures were gone.
He looked around and didn’t see them. “Figured I would talk to them. They were gone, just gone,” Brinkley said.
He thought more about what he had seen: With their lower half concealed by bushes in the caldera, he had only seen them from the waist up. “The shape that would be like their heads, it looked like they had huge hoods on. It looked like two ribbons coming off either side to a point at the top and bottom (like a banana). The right side was black, left side was white and a little shiny. Torsos were kind of black, I couldn’t see many details. It definitely looked like clothes. In middle of the oval was just gray.”
He thought maybe it was the back of hunters’ heads. “But it looked too strange, too crazy.”
Later, he drew what he could remember of them in a leather bound sketchbook he carries with him. And he drew what he saw next.
Brinkley hurried back to where Lucero was still waiting. Still no elk. “I was a little weirded out,” he told his friend.
He told Lucero he had seen a couple of hunters and that’s probably what had scared off the elk. He couldn’t bring himself at first to say what he might have just imagined.
They went back to camp. “I couldn’t take it any more,” Brinkley said. “I told him what I saw was weird. They were too tall, their heads were too big to be hunters.”
“Anyone who knows me knows I don’t tell these weird stories.”
Lucero said he had known something was up when Brinkley had walked quickly and noisily up to his position at the field. Normally his friend is quiet, a hunter’s slower, more measured speed through the bushes.
After Brinkley told him, Lucero felt a little weird, too. “I didn’t know what to believe,” Lucero said.
Brinkley kind of wrote off what he saw.
A Strange Structure
On Labor Day (Sept. 2), they headed out again to hunt early in the morning and hiked all around the area. No elk. They got back to their Jeep at about 2:30 p.m.
“We couldn’t figure out why there was no elk,” Brinkley said.
They decided to drive to the other side of the mountain and see if there were other hunters or four-wheelers scaring off the elk. As they drove, the men saw no signs of any wildlife at all, they said.
They drove about 10 minutes, when they saw it. They both work with movie sets. At first they thought it was a movie base camp. “It’s this big tent structure, like a circus tent, 50-60 feet tall. Coming off the left of it was this long building, almost like what you would build for an archery lane for target practice. It was a third the height, but really long, maybe a couple hundred feet.”
They were about a quarter mile away and couldn’t see the bottom of the structure.
They watched it for about a minute as they drove.
“What is it,” he asked Lucero, “a base camp for a movie? Or are they building an alien ship set?”
They drove down a little hill, lost sight of the structure for at most five seconds, Brinkley said.
“When we topped the hill, it was gone. Just gone.”
Lucero said he was watching it the whole time while Brinkley drove except for those few seconds. “There was no dust, there was nothing,” Lucero said.
They drove around the area searching for what they had seen until dark.
“I just know it was real,” Brinkley said. “It was huge and white and then gone.”
When the two men reached a place with cell signal, they told a few friends what they had seen. They thought about calling the Air Force. A friend put them in touch with Peter Davenport, longtime executive director of the National UFO Reporting Center in Washington state.
Davenport confirmed they had called him. “It was a dramatic story,” he said. “If it is true, it is profoundly unsettling.”
He said out of the thousands of calls he gets every year about supposed alien sightings, they rarely describe seeing aliens on the ground.
They aren’t the first hunters to see something they can’t explain. Four hunters in Challis, Idaho, in 2000 described having a large triangular craft hover a couple of hundred feet above them before moving off over the mountains.
After listening to some 350,000 phone calls over 25 years, Davenport thinks he can tell those that are credible.
This was one of them, he said.
Brinkley and Lucero said they weren’t drinking and weren’t on drugs.
The hardest thing is telling their story. “People probably think we are insane,” Brinkley said
He said he didn’t believe in UFOs. “I sure do now,” he said.
Lucero said he doesn’t know about aliens. “I just know I’ve never seen anything that big just disappear.”
“The two aliens, you can say I imagined that. But you cannot explain something that big just — gone,” Brinkley said.
After telling their strange tale, the hunters did what they came to do – go try one more time to find elk.
New Mexico Hunters Have ET Encounter on Pot Mountain
Let’s answer a few of the obvious questions right away. Yes, there really is a Pot Mountain in New Mexico. No, it has nothing to do with marijuana. Yes, that may absolve the two ET-spotting hunters from accusations that they were high when they claim to have seen two tall big-headed, half-black/half-white aliens on Pot Mountain. No, they weren’t trying to be politically correct with that description. Yes, one saw the creatures and both saw something that was either their tent or their means of transportation. And no, they didn’t take any pictures. However, it’s an interesting story and UFO expert believes their sincerity in telling it.
“We’re a couple of guys that don’t believe in much, but we believe now.”
Josh Brinkley and Daniel Lucero were still in their bow-hunting camouflage clothing when they told their story to the Taos News. The friends and co-workers have been hunting together for elk for years, but this was Lucero’s first time on Cerro de la Olla – an inactive volcanic mountain northwest of Taos named Mountain of the Pot or Pot Mountain because of its pot shape. Brinkley brought him there a few days before the September 1 opening day of elk season to scout for some good spots. However, he was alone and wondering why there were no elk around when he had his first close encounter.
“[I noticed the] very tall shapes of these beings, standing side by side, staring right at me. The shape that would be like their heads, it looked like they had huge hoods on. It looked like two ribbons coming off either side to a point at the top and bottom (like a banana). The right side was black, left side was white and a little shiny. Torsos were kind of black, I couldn’t see many details. It definitely looked like clothes. In middle of the oval was just gray.”
Brinkley estimated the creatures were 35 feet from him. As he walked around a bush to get a better look, they disappeared. He told the Taos News that he returned to Lucero but hesitated before telling him about the unbelievable encounter with the two tall beings. They returned to the same area the next day and still saw no elk. That’s when both hunters had a close encounter of the tent kind.
“It’s this big tent structure, like a circus tent, 50-60 feet tall. Coming off the left of it was this long building, almost like what you would build for an archery lane for target practice. It was a third the height, but really long, maybe a couple hundred feet.”
As they drove around to get closer, they lost sight of the structure for less than five seconds. When they had a view again of where it was … it wasn’t.
“When we topped the hill, it was gone. Just gone. There was no dust, there was nothing, I just know it was real. It was huge and white and then gone.”
They had no further encounters. In addition to the Taos News, they told their story to Peter Davenport, the executive director of the National UFO Reporting Center, who was intrigued by the witnesses claiming to see actual alien creatures and added this comment to the report of the call.
“NUFORC was impressed with what we perceived to be the apparent sincerity of the caller during the telephone conversation with him.”
One discrepancy between the two accounts – NUFORC says there were three witnesses while the Taos News says there were only Brinkley and Lucero. That might be cleared up with an official written account to NUFORC by the witnesses, but that hasn’t happened yet.
What did Josh Brinkley and Daniel Lucero see? Taos is well-known as a center for New Age beliefs, but it and New Mexico in general have had their share of strange incidents and alien encounters, ranging from the mysterious Taos hum to the Roswell UFO crash to extraterrestrials living in caverns near Dulce to the alleged 1948 ‘flying saucer’ crash in Hart Canyon near Aztec with 14 to 16 small humanoid corpses found in the wreckage.
Is the incident on Pot Mountain just a good title for a major motion picture or a real close encounter? It would have helped their case to have photos instead of drawings and another witness who is not also a friend and co-worker. It would have also helped if there were footprints of the ETs and imprints or other evidence of the mysterious tent.
Keep looking up … unless hunting season has started.
