How big is space

1. 1. How big is space ???????
2. 2. The distance from Cheddar to Bristol is approximately 32 km or 20 miles. The distance from Lands End to John O’Groats is 1664 Km or 1040 miles. Planet Earth’s circumference is 39840 Km or 24900 miles. The distance from the Earth to our moon is 382,260 Km or 237,001.2 miles. This is the furthest that humans have travelled away from Earth. The distance to Venus (our closest planet) is 42,000,000 Km or 26,000,000 miles at it’s closest point. Some Facts
3. 3. Speed of light = 1 079 252 848.8 km/hr There are 8766 hrs in 1 year A light year is the distance light travels in 1 year 1 light year = 9 460 730 472 580.8 km Nine trillion four hundred and sixty billion seven hundred and thirty million four hundred and seventy two thousand five hundred and eighty thousand point eight kilometres
4. 4. 1 light year = 9 460 730 472 580.8 km After the sun our nearest star is Proxima centauri 4.24 light years away. 4.24 ly = 40 113 497 203 742 .592km Forty trillion one hundred and thirteen billion four hundred and ninety seven million two hundred and three thousand seven hundred and forty two point five nine two kilometres = 24 925 371 582 298 . 496 miles Twenty four trillion nine hundred and twenty five billion three hundred and seventy one million five hundred and eighty two thousand two hundred and ninety eight point four nine six miles
5. 5. Proxima centauri is 24 925 371 582 298 . 496 miles away Space shuttle on average travels at 17 500 mph To reach Proxima centauri it would take the space shuttle: 1 424 306 947 hours 59 346 122 days 162 480 years !!! The object furthest away that is visible without a telescope is the Triangulum galaxy which is 3.14 million light years away. How long would the space shuttle take to reach that?!?
6. 6. The Universe 24 gigaparces or 78 billion light years across Spherical Hyperbolic Flat If the universe has a shape and size, what is beyond the universe?!?
7. 7. Assuming that the universe does have a shape and size. This means that it would be: 737,936,976,861,302,400,000,000 Km from one side to the other! Seven hundred and thirty seven sextillion, nine hundred and thirty six quintillion, nine hundred and seventy six quadrillion, eight hundred and sixty one trillion, three hundred and two billion, four hundred million kilometres. or 458,532,778,933,183,890,960,460.8 miles How do you think that you say this number?
