What is the 2nd fastest thing in the universe?
The second and third fastest things in the universe are matter going at 99% of the speed of light, or like 99.9 or 99.99 and on, percent of the speed of light.
However the number one fastest thing in the universe belongs to 2 things, photons, which carry light, and gravitons, which carry gravity..
Why is light so much faster than sound?
Light travels much faster than sound, partly because it does not need to travel through a medium. Light can travel through a vacuum at the rate of…
What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
Which is faster than light?
Tachyons are hypothetical particles that travel faster than light. According to Einstein’s special theory of relativity – and according to experiment so far – in our ‘real’ world, particles can never travel faster than light. … Taken together, all these virtual particles make up the quantum vacuum.)
What is the 30 30 rule for lightning?
Use the 30/30 rule! Go indoors if you see lightning and can’t count to 30 before hearing thunder. Stay inside for 30 minutes after hearing the last clap of thunder.
Can you hear thunder and see lightning at the same time?
Since light travels faster than sound, the thunder is heard after the lightning. If you see lightning and hear thunder at the same time, that lightning is in your neighborhood. … Lightning from this area is called positive lightning.
Is a missile faster than a bullet?
Wall said the test missile was traveling 3,200 feet per second, which equates to 2,182 miles an hour. … In comparison, a 9mm bullet travels at about 900 feet per second.
Is light faster than darkness?
/ FromQuarkstoQuasars. Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. … In this respect, darkness has the same speed as light. However, in some instances, darkness actually moves faster than light.
Can humans travel a light year?
As of January 25, 2020, Voyager spaceprobe, the farthest human-made object from Earth, is 200 AU away. … Light in a vacuum travels around 300,000 kilometres (186,000 mi) per second, so 1 light-year is about 9.461×1012 kilometers (5.879 trillion miles) or 63,241 AU.
What color Diffracts the most?
redIn the visible wavelengths of the electromagnetic spectrum, red, with the longest wavelength, is diffracted most; and violet, with the shortest wavelength, is diffracted least. Because each color is diffracted a different amount, each color bends at a different angle.
Does light make sound?
Light itself does not make any sound but it can be converted to material vibration through being absorbed by matter. So if a molecule floating in the air absorbed a photon and started to move it would be producing a vibration by bumping into other molecules.
What do light and sound have in common?
Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. … Sound is a form of mechanical energy caused by vibrations of matter. Light is electromagnetic energy caused by interacting electric and magnetic fields.
What came first sound or light?
Light came first. Sound is produced by vibrations in matter, initially there was all energy then after Big-Bang some of it changes to matter, only after that there is chance of producing sound. Molecules vibrate, then sound is produced, initially everything was energy how sound can be produced.
What comes first thunder or light?
If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. We can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder.
Which travel faster sound or light?
The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.
Are light and sound the same thing?
Light and sound are not on the same spectrum. Light belongs to the electromagnetic spectrum but sound does not. … Sound however, is a longitudinal wave – a wave that vibrates in the direction that it is travelling. Sound requires a medium to travel through whereas electromagnetic waves like visible light do not.
What is the fastest thing in the world?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
Does anything travel faster than light?
For one thing, while nothing has ever been observed travelling faster than light, that does not mean it is not theoretically possible to break this speed limit in very special circumstances. … There are galaxies in the Universe moving away from one another at a velocity greater than the speed of light.
Is light faster than electricity?
Light travels through empty space at 186,000 miles per second. The electricity which flows through the wires in your homes and appliances travels much slower: only about 1/100 th the speed of light.
Can anything travel faster than sound?
Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space.
Is lightning hotter than the sun?
Lightning is four times hotter than the sun. … A return stroke of lightning, that is, a bolt shooting up from the ground to a cloud (after a stream of electricity came downward from a cloud) can peak at 50,000 degrees Fahrenheit (F). The surface of the sun is around 11,000 degrees F.
