What would happen if a rock hit Earth at the speed of light?
It wouldn’t annihilate the earth completely, but it would wipe out everything on the surface of our planet, leaving it a glowing rock with a surface temperature of about 5,000–6,000º C, or a bit hotter than the surface of the sun. We would all die, of course.
What would happen if a golf ball hit the Earth at the speed of light?
The golf ball would require infinite energy to decelerate, from the speed of light to any number smaller than the speed of light. As any physicist will tell you, the earth will not supply infinite deceleration, so the golf ball will pass clean through the earth.
What would happen if something hit you at the speed of light?
It travels at a steady rate of 186,282 miles (299,792 kilometers) per second. Even if it were physically possible to propel ourselves to such speeds (spoiler alert: it isn’t), as you gain the necessary momentum to match the speed of light, your mass would become infinite.
What if a needle hit the earth?
The mass of our planet is an immense 5.9 x 10^24 kg. The needle is moving at the speed of light, or around 300,000,000 m/s. And such a wave of kinetic energy, combined with the impact of the collision, will probably destroy our planet and all life on it.
Is it physically possible to stop time?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. To phrase this tenet in a more friendly manner, it means that a light beam’s speed remains unchanged even if the observer moves relative to it.
What happens if a grain of sand hits the earth at light speed?
The likelyhood that a grain of sand, moving at or near the speed of light, would actually make it to the surface of the earth is so remote as to be ignored. A grain of sand moving at that speed, and hitting the atmosphere, would be destroyed before ever reaching the surface.
How big was the impact of the asteroid that hit Earth?
According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.
Will the Near Earth object 2004 MN4 ever hit Earth?
For a while astronomers thought it might. On Christmas Eve 2004, Paul Chodas, Steve Chesley and Don Yeomans at NASA’s Near Earth Object Program office calculated a 1-in-60 chance that 2004 MN4 would collide with Earth. Impact date: April 13, 2029.
What would happen if there was no sunlight for a year?
The combination of dust from the impact and soot from the forest fires will remain in the Earth’s atmosphere for a year or so, blocking the light of the Sun. Without sunlight, much of the Earth’s plantlife, on land and in the sea, will die.
Does the Earth Move at the speed of light?
Gradually you see days and nights becoming shorter, getting repeated in shorter spans of time. Soon, the Sun appears to rise one hour after Sunset and so on… Taking this fast forward, we see that the Earth’s rotational speed has come very close to the speed of light. BUT it does not touch the speed of light.
