10 Facts About Universe Became A Myths According to science

10 facts about universe all of us thought were true, but it’s a myth according to science, Here are some of the most common myths, misconceptions, and inaccuracies I’ve encountered that should be cleared for you.

MYTH: There are only three phases of matter: solid, liquid, and gas

Solid, Liquid and Gas ?? you forgot one, A big one: plasma.

It’s easy to assume solids are the most abundant form of matter in the cosmos, since we all live on a giant rock. But plasma is vastly more abundant – stars, including our sun, are gigantic orbs of glowing plasma.

There are many more phases of matter as well, like supercritical fluids, which occur on Venus’ surface. But solid, liquid, gas, and plasma are the main ones.

MYTH: The vacuum of space is always cold

If you’re in total darkness at the coldest spot in the known universe, the vacuum of space can get down to -454 degrees Fahrenheit. i don’t wanna imaging that 🙁

But in sunlight near Earth, temperatures can swing to a boiling 250 degrees Fahrenheit. That’s why astronauts wear reflective white spacesuits. i don’t wanna imaging that too 🙁

MYTH: Nothing can go faster than light

light can move at 299,792,458 meters per second in a vacuum. But it slows down when it travels through different substances. For example, light moves 25% slower through water and 59% slower through diamond.

Particles like electrons, neutrons, or neutrinos can outpace photons of light in such materials — though they have to bleed off energy as radiation when they do.

What about light in a vacuum? Even then, the expanding fabric of space once exceeded light-speed during the Big Bang.

Physicists also think two quantum-entangled particles might be able to “move” or teleport their states instantly, no matter how much distance separates them.

MYTH: Summer is warm because the Earth is closer to the sun

When it is summer in the Northern Hemisphere, the Earth is not closer to the sun. In fact, it’s quite the opposite: The planet is at its farthest point from the sun during the summer.It is warmer during the summer because Earth is tilted. During its orbit, our home planet’s tilt allows the sun’s energy to hit us more directly.

MYTH: Astrology can predict your personality or your future

Where the sun, planets, and moon were located when you were born? based on the answer of this Question, some people can predict your personality or your future.

That’s what astrology claims to do — and as much as 2% of people strongly buy into it.

Yet thorough scientific investigations of astrology have repeatedly failed to back up any predictions from an astrological sign or horoscope.

In a seminal 1985 study published in the journal Nature, scientists used a nonbiased, double-blind protocol and worked in conjunction with some of the top astrologers in the US to test the predictive power of astrological signs.

The results? The astrological predictions were no better than chance.

MYTH: The sun is yellow

You’d be forgiven for thinking the afternoon sun looks yellow – but the light it gives off is technically white.

The Earth’s atmosphere makes the star appear yellow. The gases bend the light in an effect called Rayleigh scattering, which is what also makes the sky appear blue and causes sunsets to blaze into brilliant oranges and reds.

It also doesn’t help that astronomers classify the sun as a yellow main-sequence G-type star, or “yellow dwarf” — which has nothing to do with color.

MYTH: The asteroid belt is dangerous

Movie scenes of spaceships flying through a dense field of tumbling, colliding rocks are not realistic.

The asteroid belt — a zone 200 million to 300 million miles from the sun — is an incredibly lonely and desolate void.

In fact, if you pulled all the asteroids in that belt together, they’d be only about 4% of the mass of Earth’s moon.

That’s why NASA gets excited when it catches even one asteroid colliding with another.

MYTH: Going into space makes you weightless

Most scientists agree that space begins 62 miles up, where the Earth’s atmosphere is more or less a vacuum.

Yet going past this point does not magically make you weightless. If you were in an accelerating rocket, you would feel many times Earth’s gravity. It’s only when you start falling that you’d feel weightless.

To orbit something is to fall forever around that object. The moon around the Earth, the Earth around the sun, the solar system around the Milky Way — they’re all falling toward one another in a crazy cosmic dance.

If you were 250 miles above the Earth, you’d have to travel 17,500 mph around the planet to experience continuous free-fall — the same speed as the International Space Station and its inhabitants.

MYTH: A nuclear weapon could destroy an asteroid

Isn’t nice to defend our planet by nuking the asteroid threatening us?, in fact nuking an asteroid would not vaporize the rock.

Most asteroids are heaps of rubble, so a powerful blast would probably just break everything apart further. That’s like turning a single bullet into a shotgun blast — not a good idea if you’re trying to save the planet 😀 .

However, some researchers think a well-directed, smartly designed nuclear attack could irradiate an asteroid’s surface, vaporize some of the rock, and shoot off gases that’d push an asteroid on off-course. Phew.

MYTH: There’s a “dark side” of the moon.

It’s easy to think the far side of the moon is dark, since we never see it. But it goes through the same lunar phases as the near side, which faces the Earth — in reverse.

When there’s a new (and very dark) moon on the near side, for example, that means there’s a full moon on the far side. We just can’t see it from our vantage point.

So yes, there is a “dark side” of the moon — but it’s always moving and sometimes faces Earth directly.
