Am I ignorant as I say; 1- Time is different for different people and depends upon velocity of them. 2- Gravity isnt as we see n believe it to be its due to curving of space time. 3- Mass isnt the constant quantity. 4- Energy can be created and destroyed from and to mass respectively. 5- Light isnt wave alone it shows particle behavior too. 6- Earth isnt flat. Its round. 7- Black hole radiates radiation called hawking radiation. 8- Everything is relative except physical constant and speed of light. 9- There is speed limit of c. No one can go faster than that. 10- You can go in past simply known as time travel. 11- Gravity affects time. 12- There are extra dimensions except these three we can observe. 13- There is parallel universe at the time when we arent able to find boundary of our universe. 14- Most of the part of universe if filled with dark matter or energy to explain accelerating universe. 15- There is entropy which is ever rising thing which is simply the degree of disorder. After many billions of year its often said that the broken glass tends to rearrange in original shape. That is when universe starts contracting. 16- Light is e-m wave. In it there are mutually perpendicular to fields magnetic and electric field. They oscillate and move in the speed of c. 17- Light can be bent.( we studied it always travel straight) 18- Light travel in the form of tiny packets called quanta. 19- Photon of light cant ever be come at rest.( Mo=0) 20- When you add heat to the object, its temperature maynt change. 21- When ice floating in water melts then the level of water remains same. 22- Steel is more elastic than rubber. 23- Water is more elastic than air. 24- There are another two forces governing the universe weak and strong nuclear force along with e-m force and g.f. 25- There happens time dilation and length contraction. 26- There are anti matter of matter but our universe is matter dominated.( quark- anti quark, electron- positron, proton- anti proton, neutron- anti neutron..) 27-There are proton and neutron in nucleus which actually repel each other but they co exist in nucleus due to nuclear force. 28- Moon is falling towards us. 29- Heat can flow from colder body to higher body if external work is done. 30- You can even find the area under curve exactly which seems impossible. 31- you can convert many org. compound into ethanol n drink it.ie CH3- CH2- NH2------HONO(0-5)---------->CH3- CH2- OH CH3- CH2- Cl-----------ag. KOH-------------->CH3- CH2- OH CH3- CHO------------------[H]------------->CH3- CH2- OH etc. 32- F= ma, a= F/m, acceleration produced in body is directly proportional to the force applied and inversely proportional to mass isnt actual statement of second law. It is stated as the force applied in directly proportional to change in momentum of the object. F= k dP/dT = k dmv/dt= k m dv/dt= kma= ma k= 1 33- second law is real law of motion. Third law and first law can be derived from Newtons second law of motion. 34. 0/0, as there is 0 in the numerator isnt 0, as there is 0 in the denominator isnt infinity, as there are same number in numerator and denominator isnt 1. 35. If man has velocity of 5m/s and train has 150 m/s in same direction then the relative velocity isnt exactly 145 m/s.
