Ds (7) wants to know if anything is faster than thunder and lightning? Anyone know? TIA!

a curry-eating cheetah ?

the fastest thing in the world is light

bossykate Thu 05-May-05 16:11:59

um, thunder goes at the speed of sound and lightning goes at the speed of light? so i suppose nothing goes faster than lightning?

calling the mnet scientists on this one...

light is the fastest thing at just under three hundred thousand kilometres per second!
nothing else in the physical world approaches that. sound, ie thunder is only 330 metres per secoond. i suppose you could always say theological stuff is faster.

the fastest cake in the world is:


ha ha sorry couldnt resist

Thank you! He liked the joke too! I knew someone here would know

WWW, has he got the Guiness book of world records?

I started getting it for xmas when i was about 7 and it's Fab.

Ds1 got it last yr and I spent hours looking up all sorts of stuff.

Light isn't the fastest thing now:

Speed of light broken with basic lab kit

Electric signals can be transmitted at least four times faster than the speed of light using only basic equipment that would be found in virtually any college science department.

Scientists have sent light signals at faster-than-light speeds over the distances of a few metres for the last two decades - but only with the aid of complicated, expensive equipment. Now physicists at Middle Tennessee State University have broken that speed limit over distances of nearly 120 metres, using off-the-shelf equipment costing just $500.

Thank you toothache, I will show him that tomorrow!

stitch Thu 05-May-05 20:39:37

wow toohache. but what about relativity? and the whole mass thing? doesnt mass increase exponentially with speed? and thats why only photons can go that fast cos they have no mass? as i remember it, electrons do have a mass, tiny, but they do.
can you do a link to the article please?

get him Guiness Book of Records

then you can look up the cat one. Someone trained cats to deliver the post. The experiment failed as the cats proved thoroughly undisciplined.

makes me laugh every time.

Sorry but I just don't belive that anything moves faster than light.

WWW tell yor ds that the light moves a lot faster than the sound of the thunder, that is why yu see the flash of light before you hear the thunder.

You can also tell him that supersonic jets go faster than the speed of sound.

enid, we went to the post box this afternoon and had a loooong conversation about how letters are delivered, he thought they went right down into the ground under the letterbox, bless! God, do I HAVE to buy TGBORecords, it's sooo full of boring stuff, with the odd gem. May do.

essential for 7 year olds.

sorry it must be done.

emma go and have a little rest , footballers wives on in a minute

lol sobernow, Joan Rivers said (I paraphrase) 'you want to see a man move? Tell him you want to get married and have babies - they leave skidmarks' Thanks hmb!

Toothache Thu 05-May-05 20:44:13

Stitch - Technically it is still light..... just that they have accelerated it faster than the conventional 'speed of light' of 2.87x10 to the power of 6 m/s (if I remember correctly!!).

It's on the New Scientists website. I'll try a link.

stitch Thu 05-May-05 20:44:58

ever since they cut out yuri gagarin as the first man in space, and subsituted it with the first american in space, i dont believe anything in it

emmatmg Thu 05-May-05 20:45:08

WWW, it's great.

I still love it, but then before my maternal amnesia set in I used to be a data bank of useless information, so maybe that's why I like it.

emmatmg Thu 05-May-05 20:46:32

I think I will enid, can feel the easy watching/sleep mode kicking in as I type......ideal for for such pap TV.

Speed of Light Broken

happymerryberries Sat 07-May-05 07:19:39

This is 3 years old and has not, to my knowledge , been repeated by anyone. If someone had over turned Einstein it would have been published in a journal like 'Nature' and not the new scientist, which while good is realy more a general interest magasine than a scientific journal.

Breaking the speed of light would have turned all of 20th centuary physics on its head!
