The first two images are tesseracts and the second two are 4D spheres. 1 Dimension: in a universe with one dimension, particles can only move in a line so from left to right not up and down. _____________________________
2 Dimensions: this is made up of an infinite amount of 1D universe and particles would be able to to move in two dimensions, up down left and right. Now if there was an organism living in a 2 dimensional it would see things in 1 dimension just like we see things in 2 dimensions and our brain is what is able to interpret depth by using two eyes and our brain. When we hold our finger in front of our face and move it, we can see that it appears to have moved relative to the background. Our brains see this difference and this allows us to estimate how far away they are. In a 2D universe there would be no background as such to see the “finger” moving against so it would be seen in 1D although it’s impossible to visualise anything in 1 dimension.
3 Dimensions: we live in 3 spatial dimensions in our universe which is made up of an infinite amount of 2D universes. We see things in 2 dimensions. A common misconception is that time is the 4th dimension but it doesn’t really make sense because it is present in every spatial dimension.
4 Dimensions: this is almost impossible to try and visualise. There are some people who claim they can think in 4 and even more dimensions. Now, a 4th dimensional organism would see things in 3 dimensions. If they came to our universe then they would be seeing absolutely every line of every shape but it wouldn’t be possible for a 4D being to like in 3D, it would be like us living in 2D. Above I have some 4D shapes to give you an idea of how we can represent them. It’s better to watch the inks though.

Bill Nye reading mean tweets
Hello! I'm a person, and I find physics (specifically astrophysics) to be incredibly interesting, and I'd like to know more about it. Have any idea on what I should read/watch to get more educated on the subject? I don't know where to start ^^".
Well I get a lot of my updates in the science world from here, http://www.sciencedaily.com/news/space_time/astrophysics/ just look under the astrophysics section then when you get to understand some of the key concepts the look up papers on science direct and google scholar for the best free papers :)

New Horizons: Enhanced false-color mosaic of Pluto, July 14th 2015
New Horizons scientists use enhanced color images to detect differences in the composition and texture of Pluto’s surface. When close-up images are combined with color data from the Ralph instrument, it paints a new and surprising portrait of the dwarf planet. The “heart of the heart,” Sputnik Planum, is suggestive of a source region of ices. The two bluish-white “lobes” that extend to the southwest and northeast of the “heart” may represent exotic ices being transported away from Sputnik Planum. Four images from New Horizons’ Long Range Reconnaissance Imager (LORRI) were combined with color data from the Ralph instrument to create this enhanced color global view. The images, taken when the spacecraft was 280,000 miles (450,000 kilometers) away, show features as small as 1.4 miles (2.2 kilometers).

Hubble Peers into the Heart of a Galactic Maelstrom
This NASA/ESA Hubble Space Telescope image shows Messier 96, a spiral galaxy just over 35 million light-years away in the constellation of Leo (The Lion). It is the nearest group containing both bright spirals and a bright elliptical galaxy (Messier 105).

High above the crowded streets of Addis Ababa, among fields where farmers lead oxen dragging wooden ploughs, sits Ethiopia’s space programme.
Perched at the top of the 3200m-high Mount Entoto, two metal domes house telescopes, each a metre in diameter. In operation for only a few months, they have propelled Ethiopia into an elite club of African countries to have embarked on a space programme.
Its programme is aimed at giving the country a technological boost that will aid its already rapid development.
“Science is part of any development cycle,” says Abinet Ezra, spokesman for the Ethiopian Space Science Society. “Without science and technology nothing can be achieved.
“Our main priority is to inspire the young generation to be involved in science and technology.”
The society, funded by Ethiopian-Saudi business tycoon Mohammed Alamoudi, was set up in 2004 to promote astronomy. But its supporters have had a tough ride setting up the space programme.
For the past decade, a handful of enthusiasts - including Solomon Belay, director of the observatory and a professor of astrophysics - battled with the authorities to convince them that, in a country that is still one of the poorest in the world, where malnutrition is still a threat, the exploration of space is not a luxury. Ethiopian strongman Meles Zenawi, who died in 2012, considered them dreamers.
“People said we were crazy,” says Belay.
The R39-million space observatory is, above all, a symbol. The site at Entoto, often hidden by clouds during the rainy season and close to the lights of Addis Ababa, struggles to compete with the world’s major observatories, including the far larger Southern African Large Telescope in South Africa.
But Ethiopia has plans, including to build a far more powerful observatory in the northern mountains around Lalibela, far from city lights.
The government hopes to launch a national space agency - and to put an Ethiopian satellite in orbit within five years, for the monitoring of farmland and to boost communications.
“We are using space applications in everyday activities, for mobile phones, weather - space applications are fundamental,” says Kelali Adhana, the International Astronomical Union chief for East Africa, based in Ethiopia. “We cannot postpone it, otherwise we allow ourselves to live in poverty.”
At Ethiopia’s Institute of Technology, in the northern town of Mekelle, scientists plan to test the first Ethiopian rocket to go more than 30km, although that is still far from the 100km frontier beyond which the Earth’s atmosphere gives way to space proper.

What are Perseid Meteors, and why should you be excited for them this year? Let us tell you!
The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus.
Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, forecasters say the show could be especially awesome this year because the Moon is nearly new when the shower peaks on Aug. 12-13.
The best place to view the event is away from city lights around midnight. Under a clear, dark sky forecasters predict meteor rates as high as 100 per hour on peak night. So, get outside, look up and enjoy the show!
If your area has poor visibility on the peak night, we’ve got you covered! We’ll be hosting a live broadcast about the meteor shower from 10 p.m. EDT Wednesday, Aug. 12, to 2 a.m. Thursday, Aug. 13. In addition to footage from our live skycam, the program will highlight the science behind the Perseids, as well as our research related to meteors and comets. Tune in on NASA TV or our UStream Channel.
I love space. I've been to space camp in Huntsville Alabama and I am planning on going every summer. I look forward to be an astronaut for nasa on the sls that is planned to be launched 2018. And the manned mission 2030. So yeah I won't let anything get in my way.
