What are the strongest scientific evidences proving the Apollo moon landings were real?

Independent, third‑party measurements and physical samples provide the clearest scientific proof that Apollo landed humans on the Moon: Apollo returned about 382 kg (842 lb) of lunar rock and soil tha...

Which planet has the largest volcano in the solar system?

Mars hosts the largest known volcano in the Solar System: Olympus Mons, a shield volcano about 21–22 km high and roughly 370–700 km across, covering some 300,000 km² — far larger than any terrestrial ...

What evidence do moon-landing hoax proponents cite about the flag waving and shadows in Apollo photos?

Moon‑landing hoax proponents point mainly to two visual puzzles in Apollo photos and film: the U.S. flag appears to “wave” as it’s planted, and shadows in still images fall non‑parallel or show bright...

What were the measured radiation doses for each Apollo 11 astronaut during the mission?

NASA’s mission dosimeters and later analyses show Apollo astronauts received small cumulative doses on the order of tenths of a rad (0.18–0.46 rad commonly reported), roughly comparable to a couple of...

Did the Apollo 11 flag actually move after astronauts left in July 1969?

There is broad agreement in available reporting that Apollo 11’s flag was planted, briefly appeared to “wave” in TV footage because of handling, and very likely did not remain upright after the lunar ...

Are there documented responses from GPS/satellite engineers to flat-Earth objections?

There is consistent, though not exhaustive, public documentation from engineers and domain experts saying GPS and satellite systems depend on a spherical Earth and would not work on a flat-Earth model...

Is the moon made out of cheese

The short answer: no — the Moon is not made of cheese; it is a rocky body whose composition has been measured directly by sample-return missions and remotely by spacecraft and telescopes (available so...

Is Jupiter the only gas giant in the solar system?

Jupiter is not the only gas giant in the Solar System: mainstream sources group Jupiter and Saturn as the Solar System’s gas giants and often place Uranus and Neptune in a related but distinct “ice gi...

Can mass objects travel the speed of light?

Objects with nonzero rest mass cannot be accelerated to light speed because the Lorentz factor γ → ∞ as v → c, which makes kinetic energy diverge and would require infinite energy to reach c . Modern ...

Did NASA or the Lunar Reconnaissance Orbiter (LRO) specifically image the Apollo 11 flag in 2009 and later?

NASA’s Lunar Reconnaissance Orbiter (LRO) began returning images of Apollo sites in July 2009 and has since captured higher-resolution passes that show lunar module descent stages, rover tracks and, i...

How was Olympus Mons on Mars discovered and measured?

Astronomers first recognized Olympus Mons as a bright albedo patch called Nix Olympica in 19th‑century telescopic maps, but its true size and nature — a 600–700 km wide shield volcano rising ~21–22 km...

What evidence supports the claim that JWST detected an object from another universe?

No credible evidence in the provided reporting shows JWST has detected an object “from another universe”; available sources document JWST discoveries of interstellar visitors (3I/ATLAS), very distant ...

What are scientific explanations for why the horizon appears flat to the naked eye?

The horizon looks flat to human eyes primarily because of perspective and the enormous scale of Earth: an Earth radius of ~6,400 km compared with a person’s height makes the local tangent line essenti...

Have later lunar images or experiments confirmed how flags behave on the Moon?

Later imagery and missions confirm that most Apollo flags remained standing into the 21st century but are likely degraded and color‑bleached; NASA’s Lunar Reconnaissance Orbiter imagery shows at least...

How do lunar laser ranging experiments using Apollo retroreflectors confirm the landings?

Lunar laser ranging (LLR) uses laser pulses fired from Earth that return from corner-cube retroreflector arrays left on the Moon by Apollo 11, 14 and 15 (and later robotic missions), enabling round‑tr...
