Observatory There are a great deal of problems with this due to different errors in the readings , so to start with I've simply taken the average reading on each day . I've used this to calculate the variance from the average at each 5 minute interval during each day , and then averaged all these . together This doesn't get a nice result of the diurnal magnetometer reading cycle so I've excluded everything outside one

The extreme gravity bends light as it passes through and blurs the details of the event horizon , the region closest to the black hole . Astronomers using the Event Horizon Telescope EHT just conducted test observations aimed at
As it’s name suggests, dark matter is dark! That means it’s largely invisible to us and only detectable through its interaction with gravity. One of the leading theories to explain the stuff that makes up the majority of the matter in the Universe are WIMPs, Weakly Interacting Massive Particles. They are just theories though and …
