What if we blew up the Moon? If the moon exploded, the night sky would change. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
Likewise, What would happen if the Moon disappeared for 5 seconds?
Thereof, What if a nuke went off in space? If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.
What if Earth had two suns?
The Earth’s orbit could be stable if the planet rotated around the two stars. The stars would have to be close together, and the Earth’s orbit would be further away. … Most likely, beyond the habitable zone, where the heat of the suns wouldn’t be enough to keep our water in a liquid state.
Can we nuke the sun?
The sun is a nuclear furnace that has a mass more than 300,000 times the mass of the Earth. It is an ongoing thermonuclear reaction on such a huge scale that the human brain literally has trouble conceptualizing it. Originally Answered: What would happen if we nuked the sun? Absolutely nothing.
What would happen if the Sun died?
After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. … While the Sun won’t become a red giant for another 5 billion years, a lot can happen in that time.
What would happen if the Sun went out?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.
Is Nagasaki still radioactive?
The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies. … Roughly 80% of all residual radiation was emitted within 24 hours.
Can you survive a nuclear blast in a fridge?
GEORGE LUCAS IS WRONG: You Can’t Survive A Nuclear Bomb By Hiding In A Fridge. … “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said.
Do explosions make sound in space?
Sound needs a medium to travel (such as air), but space generally doesn’t have it. Therefore, sound can’t really propagate in space. So you can’t hear an explosion or any other sound in space.
What if Earth had 100 moons?
What would happen if we had blue sun?
What if Earth had ring?
Earth’s hypothetical rings would differ in one key way from Saturn’s; they wouldn’t have ice. Earth lies much closer to the sun than Saturn does, so radiation from our star would cause any ice in Earth’s rings to sublime away. Still, even if Earth’s rings were made of rock, that might not mean they would look dark.
What would happen if we nuked the Earth’s core?
Originally Answered: What would happen if a nuke was detonated in the Earth’s core? Nobody Would Die™ The energies in the core, and the presence of radioactive and heavy metals are already so great that any device that magically placed there would make a blip.
What would happen if the Sun exploded?
The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
What would happen if nuked the Sun?
Nothing, it’s sort of constantly nuking itself. Large solar flares, natural explosions on the surface of the Sun, can release about 22 million times the energy that would be produced by setting off our entire global nuclear arsenal.
How long will humans last?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
What will happen in 1 billion years?
In about one billion years, the solar luminosity will be 10% higher than at present. This will cause the atmosphere to become a “moist greenhouse”, resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end, and with them the entire carbon cycle.
How cold would Earth be without the sun?
And without sunlight, the Earth would get very, very cold. Earth’s surface temperature now averages about 57 degrees Fahrenheit, but by the end of the first week without the sun, the average surface temperature would be below the freezing point.
How cold would the Earth be after 1 year without the sun?
In a year, it would dip to –100°. The top layers of the oceans would freeze over, but in an apocalyptic irony, that ice would insulate the deep water below and prevent the oceans from freezing solid for hundreds of thousands of years.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
Is Chernobyl still burning?
The power plant itself, and the cities of Chernobyl, and Pripyat survived “unscathed”. President Volodymyr Zelensky disclosed on 26 April that the fires had ravaged about 11.5 thousand hectares.
Where is the most radioactive place in the world?
2 Fukushima, Japan Is The Most Radioactive Place On Earth
Fukushima is the most radioactive place on Earth. A tsunami led to reactors melting at the Fukushima nuclear power plant. Even though it’s been nine years, it doesn’t mean the disaster is behind us.
Do people still live in Chernobyl?
To this day, more than 7,000 people live and work in and around the plant, and a much smaller number have returned to the surrounding villages, despite the risks. … Since 2016, a new safe containment unit with a rounded roof covers the remains of Reactor Number Four at the Chernobyl Nuclear Power Plant.
