If Einstien's Theory of Relativity/ Euclidian Geometry?

Question

If Einstien's theory of Relativity proves that Euclidian Geometry is not always correct depending on the strength of a gravitational field, then why isn't only non-euclidian geometry applied universally? Is it because Euclidian Geometry is right most of the time?

Answer 1

most of the time you are working on a scale when the differences between those two will be so small as to me immeasurable. Since Euclidian geometry is so much easier to work with, we use that. The same is true with Newtonian physics. For every day purposes there is no reason to use relativity. It's only when you start working on extremely massive scales ( galaxies ) and/or speeds approaching the speed of light that it matters at all.

Answer 2

Because while relativity will always give the correct answer in all cases, in most applications (ie those we directly experience) relativity reduces to to euclidian/newtonian. It's kind of like how many decimal places do you need for pi? Usually, 3.14 is good enough, so there is no point in going out a million decimal places or more. Using euclidian geometry is like 3.14 for pi. You could compute all those extra decimal places, but typically what would be the point?

Answer 3

Euclidean geometry relies on entities that do not exist in reality - such as "plain" "point" "straight line" and so forth. When these entities are assumed, Euclidean geometry works perfectly.
When we need a straight line, for instance, we can use a laser. It is certainly "straight" enough to do most anything we need to do. However, A laser on the earth's surface is bent toward the surface due to the earth's gravity in an arc equal to a circle with a diameter of one light year.
As you can see, Euclidean geometry works fine for most every endeavor we choose to attempt - when we seek the true workings of the universe, however, we cannot assume "straight lines" and "points" and "plains."

Answer 4

Ahhh, Einstein is incorrect because, he did not take darkish count into result. E=MC squared ok, the position is the darkish count in that formula? / idea... so,, he's precise to an quantity, in his formula/idea....: yet he's finally incorrect. My my. the international does favor more beneficial scientists. huge, severe call for, DAMMITT! do not human beings recognize that lifestyles is, :actually IS what we make of it? ok, So enable's all keep sucking oil and gas from less than our feet...... UM, WHAT MAKES OUR floor... enable's keep taking it... till our floor crumbles.WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE... do not human beings opt for to work out different planets? properly? in the adventure that they do.... Then that is time mor eople cared about living in this one. it is unhappy, how insignifigant, the international has made NASA, at the same time as... We, I propose they...are the in effortless words ones who actual recognize what's happening.

Answer 5

yes its because the effects of relativity are generally small under most circumstances, so any error in euclidean geometry is negligible.

Answer 6

A theory does NOT prove anything. It must first become a law, and it is not, therefore Euclidean geometry still applies.
