What if there is no sun?
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..
How fast is the Milky Way moving towards Andromeda?
402,000 kilometers per hourCurrently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years.
What if Moon didn’t exist?
Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That’s because the Earth’s rotation slows down over time thanks to the gravitational force — or pull of the moon — and without it, days would go by in a blink.
What would happen if we nuked the moon?
The W25 would be carried by a rocket toward the shadowed side of the Moon where it would detonate on impact. The dust cloud resulting from the explosion would be lit by the Sun and therefore visible from Earth.
Are galaxies moving faster than light?
As dark energy causes the universe to expand ever-faster, it may spur some very distant galaxies to apparently move faster than the speed of light. … Over and over (and over and over) we’re told the supreme iron law of the universe: Nothing — absolutely nothing — can go faster than the speed of light. Done.
How fast is the Earth moving through space?
30 kilometers per secondAs schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.
Is the Milky Way moving through space?
The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).
What direction is the Milky Way moving?
Weather it rotates clockwise or counter-clockwise it depends on how you could look at it. In space there is no up or down. The MilkyWay rotates in the direction in which the arms trail the rotation movement. Also keep in mind the solar system’s ecliptic plane is not in the same general plane of the Galaxy.
What if Earth stopped spinning?
If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. … This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.
Why does the moon not spin?
The Moon does not rotate. The Moon does spin on its axis, completing a rotation once every 27.3 days; the confusion is caused because it also takes the same period to orbit the Earth, so that it keeps the same side facing us.
Will Earth ever stop spinning?
The Earth will never stop rotating. Earth rotates in the purest, most perfect vacuum in the whole universe—empty space. Space is so empty, so devoid of anything to slow the Earth down, that it just spins and spins, practically without friction.
How fast are we hurtling through space?
1700 km/hrYet we know — at a cosmic level — we’re not so stationary after all. For one, the Earth rotates on its axis, hurtling us through space at nearly 1700 km/hr for someone on the equator.
Can we survive without moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
What would happen if everyone jumped at once?
What if we all jumped at once? Because people are spread somewhat equally around the planet’s spherical surface , if we all jumped in place, nothing much would happen — all our lift-offs and impacts would cancel each other out, resulting in zero net force on the Earth, according to work by physicist Rhett Allain.
How fast is the universe expanding in mph?
Credit: ESA/Hubble & NASA, RELICS; Acknowledgement: D. Coe et al.) Already mindbogglingly large, the universe is actually getting bigger all the time. Some of the nearest galaxies to ours are receding at a rate surpassing 240,000 kilometers per hour (150,000 miles per hour).
